Placenta Accreta Spectrum Disorders - The Impact of the Creation of a Multidisciplinary Team on Maternal Outcomes in Portugal / Patologia do espectro do acretismo placentário - O impacto da criação de uma equipa multidisciplinar nos desfechos maternos em Portugal

Abstract Objective To describe a cohort of placenta accreta spectrum (PAS) cases from a tertiary care institution and compare the maternal outcomes before and after the creation of a multidisciplinary team (MDT). Methods Retrospective study using hospital databases. Identification of PAS cases with pathological confirmation between 2010 and 2021. Division in two groups: standard care (SC) group - 2010-2014; and MDT group - 2015-2021. Descriptive analysis of their characteristics and maternal outcomes. Results During the study period, there were 53 cases of PAS (24 - SC group; 29 - MDT group). Standard care group: 1 placenta increta and 3 percreta; 12.5% (3/24) had antenatal suspicion; 4 cases had a peripartum hysterectomy - one planned due to antenatal suspicion of PAS; 3 due to postpartum hemorrhage. Mean estimated blood loss (EBL) was 2,469 mL; transfusion of packed red blood cells (PRBC) in 25% (6/24) - median 7.5 units. Multidisciplinary team group: 4 cases of placenta increta and 3 percreta. The rate of antenatal suspicion was 24.1% (7/29); 9 hysterectomies were performed, 7 planned due to antenatal suspicion of PAS, 1 after intrapartum diagnosis of PAS and 1 after uterine rupture following a second trimester termination of pregnancy. The mean EBL was 1,250 mL, with transfusion of PRBC in 37.9% (11/29) - median 2 units. Conclusion After the creation of the MDT, there was a reduction in the mean EBL and in the median number of PRBC units transfused, despite the higher number of invasive PAS disorders.

A EBL média foi de 1.250 mL, com transfusão de PRBC em 37,9% (11/29) - mediana de 2 unidades. Conclusão Após a criação da MDT, houve redução na média de EBL e na mediana do número de unidades de PRBC transfundidas, apesar do maior número de PAS invasivos.

Tratamiento del embarazo ectópico implantado en cicatriz de cesárea: estudio de cohorte 2018-2022, Lima, Perú / Treatment of ectopic pregnancy implanted on cesarean scar: cohort study 2018-2022, Lima, Peru

Objetivos: Describir las características clínicas y el tratamiento del embarazo ectópico implantado en la cicatriz de cesárea, así como las complicaciones y el pronóstico obstétrico. Materiales y métodos: Estudio de cohorte retrospectivo de gestantes con diagnóstico de embarazo ectópico implantado en la cicatriz de cesárea según los criterios de la Sociedad de Medicina Materno-Fetal, atendidas entre enero de 2018 y marzo de 2022 en dos instituciones de alta complejidad, pertenecientes a la seguridad social, ubicadas en Lima, Perú. Se hizo un muestreo consecutivo. Se midieron variables sociodemográficas y clínicas de ingreso, diagnóstico, tipo de tratamiento, complicaciones y pronóstico obstétrico. Se hace un análisis descriptivo. Resultados: Se incluyeron 17 pacientes, de 29.919 partos. De estas, el 41,2 % recibió tratamiento médico y el resto recibió tratamiento quirúrgico. Se realizó un manejo local exitoso con metotrexato en el saco gestacional en dos pacientes con ectópico tipo 2. Cuatro de las pacientes requirieron histerectomía total. Seis pacientes experimentaron una gestación después del tratamiento, y 4 de ellas culminaron el embarazo con una madre y un neonato saludables. Conclusiones: El embarazo ectópico implantado en la cicatriz de una cesárea es una entidad poco frecuente, para la cual se cuenta con alternativas de manejo médico y quirúrgico con aparentes buenos resultados. Se requieren más estudios con mayor calidad metodológica de asignación aleatoria que ayuden a caracterizar la seguridad y la efectividad de las diferentes alternativas terapéuticas para las mujeres con sospecha de esta patología.

Objectives: To describe the clinical characteristics and treatment of ectopic pregnancy arising in the cesarean section scar, as well as its complications and obstetric prognosis. Material and methods: Retrospective cohort study of pregnant women with the diagnosis of a scar pregnancy in accordance with Maternal-Fetal Medicine Society criteria, seen between January 2018 and March 2022 in two high complexity institutions of the social security system, located in Lima, Peru. Consecutive sampling was used. Baseline sociodemographic and clinical variables were measured, including diagnosis, type of treatment, complications and obstetric prognosis. A descriptive analysis was performed. Results: Out of 29,919 deliveries, 17 patients were included. Of these, 41.2 % received medical management and the rest were treated surgically. Successful management with intra-gestational sac methotrexate was performed in two patients with ectopic pregnancy type 2. Four patients required total hysterectomy. Six patients became pregnant after the treatment and 4 completed their pregnancy with healthy mother and neonate pairs. Conclusions: Ectopic pregnancy implanted in a cesarean section scar is an infrequent occurrence for which medical and surgical management options are available with apparently good outcomes. Further studies of better methodological quality and random assignment are needed in order to help characterize the safety and effectiveness of the various therapeutic options for women with suspected scar pregnancy.

Ruptura uterina asociada con útero didelfo y placenta acreta. Reporte de caso / Uterine rupture associated with uterus didelphus and placenta accreta. A case report

Resumen ANTECEDENTES: Las malformaciones müllerianas son consecuencia de una alteración en la formación de los conductos de Müller durante el desarrollo del feto. El momento en que sucede la alteración determina el tipo de malformación. La clasificación actual es la de la American Society for Reproductive Medicine ASMR que se asocia con múltiples complicaciones obstétricas, entre las más graves está la ruptura uterina. CASO CLÍNICO: Paciente primigesta de 23 años, con 39.1 semanas de embarazo, sin antecedentes personales patológicos para el padecimiento actual, sin control prenatal, con dolor abdominal intenso generalizado y disminución de los movimientos fetales desde 12 horas previas a su valoración. Al ingreso de la paciente al hospital su feto se encontró muerto; hemoglobina de 7.9 g/dL, tensión arterial de 96-53 mmHg, taquicárdica, con datos clínicos de irritación peritoneal. En la laparotomía exploradora el feto se encontró muerto, en la cavidad abdominal. Hemoperitoneo de 1300 mL, útero didelfo, con ruptura uterina hacia el fondo. Datos de acretismo placentario. Por lo anterior, se procedió a la histerectomía obstétrica, con sangrado de 2000 cc. Fue necesaria la reanimación y la permanencia de 24 horas en la unidad de cuidados intensivos. La TAC abdomino-pélvica se reportó sin alteraciones renales, con una tumoración adherida cerca del peritoneo parietal sugerente de riñón ectópico. El puerperio trascurrió sin contratiempos por lo que fue dada de alta del hospital. CONCLUSIÓN: En el embarazo, las malformaciones müllerianas son causa de complicaciones obstétricas graves, entre ellas la ruptura uterina. El diagnóstico oportuno es decisivo para la prevención de complicaciones y el control prenatal.

Abstract BACKGROUND: Müllerian malformations are the consequence of an alteration in the formation of the Müllerian ducts during fetal development. The time at which the alteration occurs determines the type of malformation. The current classification is that of the American Society for Reproductive Medicine ASMR, which is associated with multiple obstetric complications, among the most serious of which is uterine rupture. CLINICAL CASE: A 23-year-old primigravid patient, 39.1 weeks pregnant, with no personal pathological history for the current condition, without prenatal control, with severe generalized abdominal pain and decreased fetal movements for 12 hours prior to her evaluation. On the patient admission to the hospital her fetus was found dead; hemoglobin 7.9 g/dL, blood pressure 96-53 mmHg, tachycardic, with clinical data of peritoneal irritation. At exploratory laparotomy the fetus was found dead, in abdominal cavity. Hemoperitoneum of 1300 mL, didelphic uterus, with uterine rupture towards the fundus. Data of placental accretism. Therefore, obstetric hysterectomy was performed, with bleeding of 2000 cc. Resuscitation and a 24-hour stay in the intensive care unit was necessary. The abdomino-pelvic CT scan showed no renal alterations, with an adherent tumor near the parietal peritoneum suggestive of ectopic kidney. The puerperium was uneventful, and she was discharged from the hospital. CONCLUSION: In pregnancy, Müllerian malformations are a cause of serious obstetric complications, including uterine rupture. Timely diagnosis is decisive for the prevention of complications and prenatal management.

Is There a Place for Family-centered Cesarean Delivery during Placenta Accreta Spectrum Treatment? / Existe um lugar para cesariana centrada na família durante o tratamento do espectro da placenta acreta?

ABSTRACT Objective Placenta accreta spectrum (PAS) is a cause of massive obstetric hemorrhage and maternal mortality. The application of family-centered delivery techniques (FCDTs) during surgery to treat this disease is infrequent. We evaluate the implementation of FCDTs during PAS surgeries. Methods This was a prospective, descriptive study that included PAS patients undergoing surgical management over a 12-month period. The patients were divided according to whether FCDTs were applied (group 1) or not (group 2), and the clinical outcomes were measured. In addition, hospital anesthesiologists were surveyed to evaluate their opinions regarding the implementation of FCDTs during the surgical management of PAS. Results Thirteen patients with PAS were included. The implementation of FCDTs during birth was possible in 53.8% of the patients. The presence of a companion during surgery and skin-to-skin contact did not hinder interdisciplinary management in any case. Conclusion Implementation of FCDTs during PAS care is possible in selected patients at centers with experience in managing this disease.

Resumo Objetivo O espectro da placenta acreta (do inglês placenta accreta spectrum - PAS) é causa de hemorragia obstétrica maciça e mortalidade materna. A aplicação de técnicas de parto centrado na família (do inglês family-centered delivery techniques - FCDTs) durante a cirurgia para tratar esta doença é pouco frequente. Avaliamos a implementação das FCDTs durante as cirurgias do PAS. Métodos Estudo prospectivo e descritivo que incluiu pacientes com PAS submetidos a tratamento cirúrgico durante um período de 12 meses. Os pacientes foram divididos de acordo com a aplicação de FCDTs (grupo 1) ou não (grupo 2), e os resultados clínicos foram medidos. Além disso, anestesiologistas hospitalares foram entrevistados para avaliar suas opiniões sobre a implementação das FCDTs durante o manejo cirúrgico do PAS. Resultados Foram incluídos 13 pacientes com PAS. A implementação de FCDTs durante o parto foi possível em 53,8% das pacientes. A presença do acompanhante durante a cirurgia e o contato pele a pele não prejudicou o manejo interdisciplinar em nenhum caso. Conclusão A implementação de FCDTs durante o atendimento do PAS é possível em pacientes selecionados em centros com experiência no manejo dessa doença.

Placenta Accreta Spectrum Prenatal Diagnosis Performance: Are Ultrasound False-positive Results Acceptable in Limited-resources Settings? / Desempenho do diagnóstico pré-natal do espectro da placenta acreta: Os resultados falso-positivos do ultrassom são aceitáveis em ambientes com recursos limitados?

Abstract Objective The immediate referral of patients with risk factors for placenta accreta spectrum (PAS) to specialized centers is recommended, thus favoring an early diagnosis and an interdisciplinary management. However, diagnostic errors are frequent, even in referral centers (RCs). We sought to evaluate the performance of the prenatal diagnosis for PAS in a Latin American hospital. Methods A retrospective descriptive study including patients referred due to the suspicion of PAS was conducted. Data from the prenatal imaging studies were compared with the final diagnoses (intraoperative and/or histological). Results A total of 162 patients were included in the present study. The median gestational age at the time of the first PAS suspicious ultrasound was 29 weeks, but patients arrived at the PAS RC at 34 weeks. The frequency of false-positive results at referring hospitals was 68.5%. Sixty-nine patients underwent surgery based on the suspicion of PAS at 35 weeks, and there was a 28.9% false-positive rate at the RC. In 93 patients, the diagnosis of PAS was ruled out at the RC, with a 2.1% false-negative frequency. Conclusion The prenatal diagnosis of PAS is better at the RC. However, even in these centers, false-positive results are common; therefore, the intraoperative confirmation of the diagnosis of PAS is essential.

Resumo Objetivo Recomenda-se o encaminhamento imediato de pacientes com fatores de risco para espectro placentário acreta (PAS, na sigla em inglês) para centros especializados, favorecendo assim o diagnóstico precoce e o manejo interdisciplinar. No entanto, erros diagnósticos são frequentes, mesmo em centros de referência (CRs). Buscou-se avaliar o desempenho do diagnóstico pré-natal para PAS em um hospital latino-americano. Métodos Um estudo descritivo retrospectivo incluindo pacientes encaminhados por suspeita de SAP foi realizado. Os dados dos exames de imagem do pré-natal foram comparados com os diagnósticos finais (intraoperatórios e/ou histológicos). Resultados Foram incluídos 162 pacientes no presente estudo. A idade gestacional mediana no momento da primeira ultrassonografia suspeita de PAS foi de 29 semanas, mas as pacientes chegaram ao CR de PAS com 34 semanas. A frequência de resultados falso-positivos nos hospitais de referência foi de 68,5%. Sessenta e nove pacientes foram operadas com base na suspeita de PAS com 35 semanas e houve 28,9% de falso-positivos no CR. Em 93 pacientes, o diagnóstico de PAS foi descartado no CR, com frequência de falso-negativos de 2,1%. Conclusão O diagnóstico pré-natal de PAS é melhor no CR. Entretanto, mesmo nestes centros, resultados falso-positivos são comuns; portanto, a confirmação intraoperatória do diagnóstico de SAP é essencial.

Consenso Colombiano de Tratamiento del Espectro de Acretismo Placentario (EAP) / Colombian Consensus on the Treatment of Placenta Accreta Spectrum (PAS)

RESUMEN Introducción: el espectro de acretismo placentario (EAP) es una condición asociada a sangrado masivo posparto y mortalidad materna. Las guías de manejo publicadas en países de altos ingresos recomiendan la participación de grupos interdisciplinarios en hospitales con recursos suficientes para realizar procedimientos complejos. Sin embargo, algunas de las recomendaciones de estas guías resultan difíciles de aplicar en países de bajos y medianos ingresos. Objetivos: este consenso busca formular recomendaciones generales para el tratamiento del EAP en Colombia. Materiales y métodos: en el consenso participaron 23 panelistas, quienes respondieron 31 preguntas sobre el tratamiento de EAP. Los panelistas fueron seleccionados con base en la participación en dos encuestas realizadas para determinar la capacidad resolutiva de hospitales en el país y la región. Se utilizó la metodología Delphi modificada, incorporando dos rondas sucesivas de discusión. Para emitir las recomendaciones el grupo tomó en cuenta la opinión de los participantes, que lograron un consenso mayor al 80 %, así como las barreras y los facilitadores para su implementación. Resultados: el consenso formuló cinco recomendaciones integrando las respuestas de los panelistas. Recomendación 1. Las instituciones de atención primaria deben realizar búsqueda activa de EAP en pacientes con factores de riesgo: placenta previa e historia de miomectomía o cesárea en embarazo previo. En caso de haber signos sugestivos de EAP por ecografía, las pacientes deben ser remitidas de manera inmediata, sin tener una edad gestacional mínima, a hospitales reconocidos como centros de referencia. Las modalidades virtuales de comunicación y atención en salud pueden facilitar la interacción entre las instituciones de atención primaria y los centros de referencia para EAP. Se debe evaluar el beneficio y riesgo de las modalidades de telemedicina. Recomendación 2. Es necesario que se definan hospitales de referencia para EAP en cada región de Colombia, asegurando el cubrimiento de la totalidad del territorio nacional. Es aconsejable concentrar el flujo de pacientes afectadas por esta condición en unos pocos hospitales, donde haya equipos de cirujanos con entrenamiento específico en EAP, disponibilidad de recursos especializados y un esfuerzo institucional por mejorar la calidad de atención, en busca de tener mejores resultados en la salud de las gestantes con esta condición. Para lograr ese objetivo los participantes recomiendan que los entes reguladores de la prestación de servicios de salud a nivel nacional, regional o local vigilen el proceso de remisión de estas pacientes, facilitando rutas administrativas en caso de que no exista contrato previo entre el asegurador y el hospital o la clínica seleccionada (IPS). Recomendación 3. En los centros de referencia para pacientes con EAP se invita a la creación de equipos que incorporen un grupo fijo de especialistas (obstetras, urólogos, cirujanos generales, radiólogos intervencionistas) encargados de atender todos los casos de EAP. Es recomendable que esos grupos interdisciplinarios utilicen el modelo de "paquete de intervención" como guía para la preparación de los centros de referencia para EAP. Este modelo consta de las siguientes actividades: preparación de los servicios, prevención e identificación de la enfermedad, respuesta ante la presentación de la enfermedad, aprendizaje luego de cada evento. La telemedicina facilita el tratamiento de EAP y debe ser tenida en cuenta por los grupos interdisciplinarios que atienden esta enfermedad. Recomendación 4. Los residentes de Obstetricia deben recibir instrucción en maniobras útiles para la prevención y el tratamiento del sangrado intraoperatorio masivo por placenta previa y EAP, tales como: la compresión manual de la aorta, el torniquete uterino, el empaquetamiento pélvico, el bypass retrovesical y la maniobra de Ward. Los conceptos básicos de diagnóstico y tratamiento de EAP deben incluirse en los programas de especialización en Ginecología y Obstetricia en Colombia. En los centros de referencia del EAP se deben ofrecer programas de entrenamiento a los profesionales interesados en mejorar sus competencias en EAP de manera presencial y virtual. Además, deben ofrecer soporte asistencial remoto (telemedicina) permanente a los demás hospitales en su región, en relación con pacientes con esa enfermedad. Recomendación 5. La finalización de la gestación en pacientes con sospecha de EAP y placenta previa, por imágenes diagnósticas, sin evidencia de sangrado vaginal activo, debe llevarse a cabo entre las semanas 34 y 36 6/7. El tratamiento quirúrgico debe incluir intervenciones secuenciales que pueden variar según las características de la lesión, la situación clínica de la paciente y los recursos disponibles. Las opciones quirúrgicas (histerectomía total y subtotal, manejo quirúrgico conservador en un paso y manejo expectante) deben incluirse en un protocolo conocido por todo el equipo interdisciplinario. En escenarios sin diagnóstico anteparto, es decir, ante un hallazgo intraoperatorio de EAP (evidencia de abultamiento violáceo o neovascularización de la cara anterior del útero), y con participación de personal no entrenado, se plantean tres situaciones: Primera opción: en ausencia de indicación de nacimiento inmediato o sangrado vaginal, se recomienda diferir la cesárea (cerrar la laparotomía antes de incidir el útero) hasta asegurar la disponibilidad de los recursos recomendados para llevar a cabo una cirugía segura. Segunda opción: ante indicación de nacimiento inmediato (por ejemplo, estado fetal no tranquilizador), pero sin sangrado vaginal o indicación de manejo inmediato de EAP, se sugiere realizar manejo en dos tiempos: se realiza la cesárea evitando incidir la placenta, seguida de histerorrafia y cierre de abdomen, hasta asegurar la disponibilidad de los recursos recomendados para llevar a cabo una cirugía segura. Tercera opción: en presencia de sangrado vaginal que hace imposible diferir el manejo definitivo de EAP, es necesario extraer el feto por el fondo del útero, realizar la histerorrafia y reevaluar. En ocasiones, el nacimiento del feto disminuye el flujo placentario y el sangrado vaginal se reduce o desaparece, lo que hace posible diferir el manejo definitivo de EAP. Si el sangrado significativo persiste, es necesario continuar con la histerectomía haciendo uso de los recursos disponibles: compresión manual de la aorta, llamado inmediato a los cirujanos con mejor entrenamiento disponible, soporte de grupos expertos de otros hospitales a través de telemedicina. Si una paciente con factores de riesgo para EAP (por ejemplo, miomectomía o cesárea previa) presenta retención de placenta posterior al parto vaginal, es recomendable confirmar la posibilidad de dicho diagnóstico (por ejemplo, realizando una ecografía) antes de intentar la extracción manual de la placenta. Conclusiones: esperamos que este primer consenso colombiano de EAP sirva como base para discusiones adicionales y trabajos colaborativos que mejoren los resultados clínicos de las mujeres afectadas por esta enfermedad. Evaluar la aplicabilidad y efectividad de las recomendaciones emitidas requerirá investigaciones adicionales.

ABSTRACT Introduction: Placenta accreta spectrum (PAS) is a condition associated with massive postpartum bleeding and maternal mortality. Management guidelines published in high income countries recommend the participation of interdisciplinary teams in hospitals with sufficient resources for performing complex procedures. However, some of the recommendations contained in those guidelines are difficult to implement in low and medium income countries. Objectives: The aim of this consensus is to draft general recommendations for the treatment of PAS in Colombia Materials and Methods: Twenty-three panelists took part in the consensus with their answers to 31 questions related to the treatment of PAS. The panelists were selected based on participation in two surveys designed to determine the resolution capabilities of national and regional hospitals. The modified Delphi methodology was used, introducing two successive discussion rounds. The opinions of the participants, with a consensus of more than 80 %, as well as implementation barriers and facilitators, were taken into consideration in order to issue the recommendations. Results: The consensus drafted five recommendations, integrating the answers of the panelists. Recommendation 1. Primary care institutions must undertake active search of PAS in patients with risk factors: placenta praevia and history of myomectomy or previous cesarean section. In case of ultrasound signs suggesting PAS, patients must be immediately referred, without a minimum gestational age, to hospitals recognized as referral centers. Online communication and care modalities may facilitate the interaction between primary care institutions and referral centers for PAS. The risks and benefits of telemedicine modalities must be weighed. Recommendation 2. Referral hospitals for PAS need to be defined in each region of Colombia, ensuring coverage throughout the national territory. It is advisable to concentrate the flow of patients affected by this condition in a few hospitals with surgical teams specifically trained in PAS, availability of specialized resources, and institutional efforts at improving quality of care with the aim of achieving better health outcomes in pregnant women with this condition. To achieve this goal, participants recommend that healthcare regulatory agencies at a national and regional level should oversee the process of referral for these patients, expediting administrative pathways in those cases in which there is no prior agreement between the insurer and the selected hospital or clinic. Recommendation 3. Referral centers for patients with PAS are urged to build teams consisting of a fixed group of specialists (obstetricians, urologists, general surgeons, interventional radiologists) entrusted with the care of all PAS cases. It is advisable for these interdisciplinary teams to use the "intervention bundle" model as a guidance for building PAS referral centers. This model comprises the following activities: service preparedness, disease prevention and identification, response to the occurrence of the disease, and debriefing after every event. Telemedicine facilitates PAS treatment and should be taken into consideration by interdisciplinary teams caring for this disease. Recommendation 4. Obstetrics residents must be instructed in the performance of maneuvers that are useful for the prevention and treatment of massive intraoperative bleeding due to placenta praevia and PAS, including manual aortic compression, uterine tourniquet, pelvic packing, retrovesical bypass, and Ward maneuver. Specialization Obstetrics and Gynecology programs in Colombia must include the basic concepts of the diagnosis and treatment of PAS. Referral centers for PAS must offer online and in-person training programs for professionals interested in improving their competencies in PAS. Moreover, they must offer permanent remote support (telemedicine) to other hospitals in their region for patients with this condition. Recommendation 5. Patients suspected of having PAS and placenta praevia based on imaging, with no evidence of active vaginal bleeding, must be delivered between weeks 34 and 36 6/7. Surgical treatment must include sequential interventions that may vary depending on the characteristics of the lesion, the clinical condition of the patient and the availability of resources. The surgical options (total and subtotal hysterectomy, one-stage conservative surgical management and watchful waiting) must be included in a protocol known by the entire interdisciplinary team. In situations in which an antepartum diagnosis is lacking, that is to say, in the face of intraoperative finding of PAS (evidence of purple bulging or neovascularization of the anterior aspect of the uterus), and the participation of untrained personnel, three options are considered: Option 1: In the absence of indication of immediate delivery or of vaginal delivery, the recommendation is to postpone the cesarean section (close the laparotomy before incising the uterus) until the recommended resources for safe surgery are secured. Option 2: If there is an indication for immediate delivery (e.g., non-reassuring fetal status) but there is absence of vaginal bleeding or indication for immediate PAS management, a two-stage management is suggested: cesarean section avoiding placental incision, followed by uterine repair and abdominal closure, until the availability of the recommended resources for safe surgery is ascertained. Option 3: In the event of vaginal bleeding that prevents definitive PAS management, the fetus must be delivered through the uterine fundus, followed by uterine repair and reassessment of the situation. Sometimes, fetal delivery diminishes placental flow and vaginal bleeding is reduced or disappears, enabling the possibility to postpone definitive management of PAS. In case of persistent significant bleeding, hysterectomy should be performed, using all available resources: manual aortic compression, immediate call to the surgeons with the best available training, telemedicine support from expert teams in other hospitals. If a patient with risk factors for PAS (e.g., myomectomy or previous cesarean section) has a retained placenta after vaginal delivery, it is advisable to confirm the possibility of such diagnosis (by means of ultrasound, for example) before proceeding to manual extraction of the placenta. Conclusions: It is our hope that this first Colombian consensus on PAS will serve as a basis for additional discussions and collaborations that can result in improved clinical outcomes for women affected by this condition. Additional research will be required in order to evaluate the applicability and effectiveness of these recommendations.

Achados na ressonância magnética do espectro do acretismo placentário: ensaio iconográfico / Magnetic resonance imaging findings in placenta accreta spectrum disorders: pictorial essay

Resumo Acretismo placentário é uma condição caracterizada pela implantação anormal da placenta, que pode ser subdividida em três espectros de acordo com o seu grau de invasão: placenta acreta (ultrapassa a decídua basal e adere ao miométrio), placenta increta (penetra o miométrio) e placenta percreta (invasão da serosa uterina ou de tecidos/órgãos adjacentes). A incidência de acretismo placentário aumentou significativamente nas últimas décadas, principalmente em função da elevação das taxas de cesarianas, sendo este o seu principal fator de risco. A sua identificação pré-natal precisa permite um tratamento ideal com equipe multidisciplinar, minimizando significativamente a morbimortalidade materna. Os exames de escolha são a ultrassonografia e a ressonância magnética (RM), sendo a RM um método complementar indicado quando a avaliação ultrassonográfica é duvidosa, para pacientes com fatores de risco para acretismo placentário ou quando a placenta tem localização posterior. A RM é preferível também para avaliar invasão de órgãos adjacentes, oferecendo um campo de visão mais amplo, o que melhora o planejamento cirúrgico. Diversas características na RM são descritas no acretismo placentário, incluindo bandas hipointensas em T2 intraplacentárias, protuberância uterina anormal e heterogeneidade placentária. O conhecimento desses achados e a combinação de mais de um critério aumentam a confiabilidade do diagnóstico.

Abstract Placenta accreta spectrum disorders are characterized by abnormal adhesion of the placenta that can be subdivided into three categories according to degree of invasion: placenta accreta (passing through the decidua basalis and adhering to the myometrium); placenta increta (penetrating the myometrium); and placenta percreta (invading the uterine serosa or adjacent tissues or organs). The incidence of placenta accreta has increased significantly in recent decades, mainly because of an increase in the rates of cesarean section, which is its main risk factor. Accurate prenatal identification makes it possible to institute the ideal treatment with a multidisciplinary team, significantly minimizing maternal morbidity and mortality. The examinations of choice are ultrasound and magnetic resonance imaging (MRI). When the ultrasound evaluation is inconclusive, as well as when the patient has risk factors for the condition or the placenta is in a posterior location, MRI is indicated. In cases of placental invasion of the adjacent pelvic organs, MRI is also preferable because it provides a broader field of view, which improves surgical planning. Numerous features of placenta accreta spectrum disorders are discernible on MRI, including dark intraplacental bands, uterine bulging, and heterogeneous placenta. Knowledge of these findings and the combination of two or more of them increase confidence in the diagnosis.

Placenta accreta in early pregnancy: case report / Placenta acreta en un embarazo temprano: reporte de caso

ABSTRACT First trimester placenta accreta is an uncommon event. There are few cases reported in the literature, several associated with uterine rupture and all of them with risk factors. This pathology can be life-threatening for the mother. At such an early stage of pregnancy, abnormal placentation is diagnosed mainly due to massive hemorrhage during uterine curettage. It is of extreme importance to diagnose it before delivery or uterine evacuation, to prevent associated morbidity and mortality. We present the case of a patient with placenta accreta in early pregnancy who consulted for abnormal uterine bleeding. We describe the clinical history, imaging and management of the patient.

RESUMEN La placenta acreta del primer trimestre es un evento poco común. Hay pocos casos publicados en la literatura, varios asociados a rotura uterina y en todos ellos con factores de riesgo. Esta patología puede poner en peligro la vida de la madre. En una etapa tan temprana del embarazo, la placentación anormal se diagnostica principalmente debido a una hemorragia masiva durante el legrado uterino. Es de extrema importancia diagnosticarla antes del parto o de la evacuación uterina, para prevenir la morbimortalidad asociada. Presentamos el caso de una paciente con placenta acreta en embarazo temprano quien consultó por hemorragia uterina anormal. Describimos la historia clínica, las imágenes y el manejo realizado a la paciente.

Ligadura de arterias hipogástricas previo al alumbramiento o a la histerectomía obstétrica modificada en inserción anómala de placenta / Ligation of hypogastric arteries prior to delivery or modified obstetric hysterectomy in anomalous insertion of the placenta

Resumen: OBJETIVO: Evaluar las ventajas de practicar o no la ligadura de arterias hipogástricas antes del alumbramiento o previo a la histerectomía modificada en el tratamiento quirúrgico de la inserción anómala de la placenta. MATERIALES Y MÉTODOS: Estudio de serie de casos, retrospectivo, transversal y comparativo efectuado en la Unidad Médica de Alta Especialidad, Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, de 2013 a 2019. Criterios de inclusión: pacientes con inserción anómala de placenta a quienes se practicó o no ligadura de arterias hipogástricas antes del alumbramiento o previo a la histerectomía modificada. Criterios de exclusión: pacientes que no finalizaron el embarazo en el hospital o la información en el expediente estaba incompleta. Parámetros de estudio: sangrado transoperatorio, transfusión sanguínea, morbilidad posoperatoria e ingreso a cuidados intensivos. Los desenlaces se analizaron con estadística descriptiva e inferencial. RESULTADOS: Se evaluaron 285 pacientes; 57% (n = 164) con placenta previa, 27% (n = 78) marginal y 15% (n = 43) normoinserta. El espectro de placenta acreta se encontró en 34% (n = 91) de la muestra. En el grupo de placenta previa la aplicación de la técnica disminuyó el sangrado transoperatorio (p = 0.005) y la transfusión sanguínea (p = 0.05). En pacientes con espectro de placenta acreta hubo una reducción del sangrado transoperatorio (p < 0.01), menores transfusión sanguínea (p = 0.01), ingreso a cuidados intensivos (p < 0.001) y días de estancia en cuidados intensivos (p = 0.0001). CONCLUSIONES: La ligadura de arterias hipogástricas antes del alumbramiento o previo a la histerectomía modificada en el tratamiento quirúrgico de la inserción anómala de la placenta mostró un máximo beneficio en los grupos de placenta previa y espectro de placenta acreta.

Abstract OBJECTIVE: To evaluate the advantages of performing and not performing "Hypogastric artery ligation prior to delivery or modified hysterectomy" in the surgical management of anomalous placental insertion. MATERIALS AND METHODS: A retrospective, cross-sectional, comparative, retrospective case series study conducted at the Unidad Médica de Alta Especialidad, Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, from 2013 to 2019. Inclusion criteria: patients with abnormal placental insertion who underwent hypogastric artery ligation before delivery or before modified obstetric hysterectomy, compared with those who did not have hypogastric artery ligation. Exclusion criteria: patients who did not terminate the pregnancy in the hospital or the information in the file was incomplete. Study parameters: transoperative bleeding, blood transfusion, postoperative morbidity and admission to intensive care. Outcomes were analyzed with descriptive and inferential statistics. RESULTS: 285 patients were evaluated; 57% (n = 164) with placenta previa, 27% (n = 78) marginal and 15% (n = 43) normoinsert. The placenta accreta spectrum was found in 34% (n = 91) of the sample. In the placenta previa group, the application of the technique decreased transoperative bleeding (p = 0.005) and blood transfusion (p = 0.05). In patients with placenta accreta spectrum there was a reduction of transoperative bleeding (p < 0.01), lower blood transfusion (p = 0.01), intensive care admission (p < 0.001) and days of intensive care stay (p = 0.0001). CONCLUSIONS: Hypogastric artery ligation before delivery and before modified hysterectomy in the surgical treatment of anomalous placental insertion showed maximum benefit in the placenta previa and spectrum of placenta accreta groups.

Acretismo placentário e suas complicações / Placental accretism and its complications

Acretismo é um termo genérico que significa uma invasão trofoblástica anormal da placenta em parte ou, mais raramente, na totalidade do miométrio, podendo inclusive chegar à serosa. Esse evento ocorre mais comumente em uma região de cicatriz uterina prévia, onde há um defeito na decidualização. A principal consequência disso é a necessidade frequente de histerectomia puerperal, acarretando grande morbidade materna. Este artigo apresenta o caso de uma gestante com placenta percreta, com acometimento vesical e de colo uterino que necessitou de histerectomia total. Além disso, no pós-operatório, apresentou fístula vesicoabdominal. O objetivo deste artigo é demonstrar as complicações do acretismo placentário e as maneiras de tentar reduzi-lo. O aumento nas proporções de nascimentos via parto cesariana, sem que haja evidências claras de que isso interfira na queda da mortalidade e/ou morbidade materna e neonatal, sugere que estejam sendo indicadas muito mais cesarianas que o necessário. Para redução nas taxas de cesariana e, consequentemente, das complicações dela, como nos casos de acretismo, é necessário repensar a cultura do cuidado da prática clínica em obstetrícia.(AU)

Accretism is a generic term that means an abnormal trophoblastic invasion of the placenta in part or, more rarely, in the entire myometrium, which may even reach the serosa. This event most commonly occurs in a region of previous uterine scar, where there is a decidualization defect. The main consequence of this is the frequent need for puerperal hysterectomy, causing great maternal morbidity. This article presents the case of a pregnant woman with placenta percreta, with bladder and uterine cervix involvement, who required hysterectomy. In addition, postoperatively, presented a vesico-abdominal fistula. The purpose of this article is to demonstrate the complications of placental accretism and ways to try it. The increase in the proportion of births via cesarean delivery, without clear evidences that this interferes with the decrease in maternal and neonatal mortality and/or morbidity, suggests that much more cesarean sections are being indicated than necessary. To reduce cesarean rates and consequently, its complications, as in cases of accretism, it is necessary to rethink the culture of care in clinical practice in obstetrics.(AU)

Reporte de caso: placenta percreta con previa embolización de vasos anómalos / Case Report: Placenta Percreta With Previous Embolization of Anomalous Vessels / Relato de caso: placenta percrete com embolização prévia de vasos anómalos

Resumen: el acretismo placentario es una de las complicaciones obstétricas más temidas. Se entiende como el proceso de inserción placentaria anormal, secundario a un procedimiento quirúrgico, lo que ocasiona un error de decidualización en el área cicatricial que lleva a la profundización anormal del trofoblasto. La frecuencia de esta patología ha ido en aumento debido al incremento en la tasa de cesáreas en los últimos años. El caso se presenta en el hospital Universitario Clínica San Rafael en Bogotá, se trata de una paciente de 36 años, gestación de 37,1 semanas, con antecedente de cesárea previa, en quien se evidenció percretismo placentario; luego del nacimiento, se dejó placenta in situ y así el servicio de cirugía endovascular realizó embolización de vasos anómalos, lo que disminuyó el sangrado en la histerectomía diferida. Se comprobó evolución favorable y seguimiento de la paciente hasta ser dada de alta de la institución sin complicaciones. Actualmente existen diversos abordajes terapéuticos, entre ellos la histerectomía posterior de la cesárea y el manejo médico hasta involución de la placenta e histerectomía diferida, todos encaminados a disminuir complicaciones asociadas, entre las cuales las más frecuentes son la hemorragia, los requerimientos de transfusión y los días de hospitalización e infección, con el fin de disminuir la morbimortalidad materna extrema.

Abstract: placental accretism is one of the most feared obstetric complications. It is understood as the process of abnormal placental insertion, secondary to a surgical procedure, which causes a decidualization error in the scar area leading to abnormal deepening of the trophoblast. The freguency of this pathology has been increasing due to the increase in the rate of cesarean sections in recent years. The case is presented in the hospital Universitario Clínica San Rafael in Bogotá, it is a 36-year-old patient, 37,1 weeks gestation, with a history of previous cesarean section, with an evident case of placenta percreta; after birth, placenta was left in place and thus the endovascular surgery service performed embolization of anomalous vessels, which reduced bleeding in the deferred hysterectomy. A favorable evolution was verified, and the patient was followed up until she was discharged from the institution without complications. Currently, there are several therapeutic approaches, including hysterectomy after cesarean section and medical management up to placental involution and delayed hysterectomy, all aimed at reducing associated complications, among which the most frequent are hemorrhage, transfusion requirements and days of hospitalization and infection, in order to reduce extreme maternal morbimortality.

Resumo: o acretismo placentário é urna das complicações obstétricas mais temidas. Entende-se como o processo de inserção placentária anormal, secundário a um procedimento cirúrgico, que causa um erro de decidualização na área cicatricial levando ao aprofundamento anormal do trofoblasto. A frequência dessa patologia vem aumentando devido ao aumento da taxa de cesarianas nos últimos anos. O caso é apresentado no Hospital Universitário Clínica San Rafael, em Bogotá, é uma paciente de 36 anos, 37,1 semanas de gestação, com história de cesariana anterior, na qual foi evidenciado percretismo placentário; após o nascimento, a placenta foi deixada in situ e, portanto, uma cirurgia endovascular foi feita para que fosse possível embolizar os vasos anómalos, o que diminuiu o sangramento na histerectomia tardia. Evolução favorável e acompanhamento da paciente até receber alta da instituição sem complicações. Atualmente, existem várias abordagens terapêuticas, incluindo histerectomia pós-cesariana e manejo médico até involução placentária e histerectomia tardia, todas com o objetivo de reduzir as complicações associadas, dentre as quais as mais comuns são sangramento, necessidade de transfusão e dias de internação e infecção, a fim de reduzir a mortalidade materna extrema.

Placental magnetic resonance imaging: normal appearance, anatomical variations, and pathological findings / Ressonância magnética placentária: aspecto normal, variações anatômicas e achados patológicos

Abstract Placental magnetic resonance imaging (MRI) has been increasingly requested, especially for the evaluation of suspected cases of placental adhesive disorders, generally known as placenta accreta. Abdominal radiologists need to become familiar with normal placental anatomy, anatomical variations, the current terminology, and major placental diseases that, although rare, are important causes of maternal and fetal morbidity and mortality. The aim of this didactic pictorial essay is to illustrate various findings on placental MRI, as well as to emphasize the importance of communication between radiologists and obstetricians in the search for best practices in the management of the affected patients.

Resumo A ressonância magnética placentária tem sido cada vez mais solicitada, sobretudo na avaliação de casos suspeitos de acretismo. Os radiologistas abdominais precisam se familiarizar com a anatomia placentária normal, variações anatômicas, terminologias atuais e principais doenças placentárias que, embora raras, são causas importantes de morbimortalidade materno-fetal. O objetivo deste ensaio é ilustrar, de maneira didática, diferentes achados placentários e enfatizar a importância da comunicação entre radiologistas e obstetras na busca da melhor conduta para as pacientes.

Peripartum Hysterectomies over a Fifteen-year Period / Histerectomias periparto ao longo de um período de quinze anos

Abstract Objective To determine the indications and outcomes of peripartum hysterectomies performed at Hospital de Clínicas de Porto Alegre (a university hospital in Southern Brazil) during the past 15 years, and to analyze the clinical characteristics of the women submitted to this procedure. Methods A cross-sectional study of 47 peripartum hysterectomies from 2005 to 2019. Results The peripartum hysterectomies performed in our hospital were indicated mainly due to placenta accreta or suspicion thereof (44.7% of the cases), puerperal hemorrhage without placenta accreta (27.7%), and infection (25.5%). Total hysterectomies accounted for 63.8% of the cases, andwefound no differencebetween total versus subtotal hysterectomies in the studied outcomes. Most hysterectomies were performed within 24 hours after delivery, and they were associated with placenta accreta, placenta previa, and older maternal age. Conclusion Most (66.0%) patients were admitted to the intensive care unit (ICU). Those who did not need it were significantly older, and had more placenta accreta, placenta previa, or previous Cesarean delivery.

Resumo Objetivo Determinar as indicações e os desfechos das histerectomias periparto realizadas no Hospital de Clínicas de Porto Alegre nos últimos 15 anos, bem como analisar as características clínicas das mulheres submetidas a esse procedimento. Métodos Estudo transversal de 47 histerectomias periparto realizadas no período de 2005 a 2019. Resultados Em nosso hospital, as histerectomias periparto foram indicadas principalmente por acretismo placentário ou sua suspeita (44,7% dos casos), hemorragia puerperal sem acretismo placentário (27,7%), e infecção (25,5%). Histerectomias totais corresponderam a 63,8% dos casos, e não encontramos diferença entre histerectomia total e subtotal para os desfechos estudados. Amaioria das histerectomias foi realizada dentro de 24 horas após o parto, o que estava associado a acretismo placentário, placenta prévia, e idade materna mais avançada. Conclusão A maioria (66,0%) das mulheres necessitou de internação em unidade de terapia intensiva (UTI); aquelas que não necessitaram eram significativamente mais velhas, e tinham mais acretismo placentário, placenta prévia, ou cesárea prévia.

Placental adhesion disorder: magnetic resonance imaging features and a proposal for a structured report / Desordem de adesão placentária: sinais na ressonância magnética e proposta de laudo estruturado

Abstract Placental adhesion disorder encompasses the various types of abnormal placentation that occur when the chorionic villi penetrate the uterine wall. Placenta accreta has become more common, mainly because of the increasing rates of cesarean section. Although ultrasound is the first-line imaging modality for evaluation of the placenta, it plays a limited role in cases of posterior placenta accreta and inconclusive findings. In such cases, magnetic resonance imaging (MRI) is indicated, mainly because it is a more accurate means of identifying placental invasion of extrauterine structures in high-risk pregnant women. In this review article, we present the ten major and minor MRI features of placental adhesion disorder, as described in the international literature. In addition, we propose a template for structured reports of MRI examinations of the placenta. We have also devised a guided questionnaire in order to identify risk factors in patients scheduled to undergo such examinations, with the objective of facilitating the multidisciplinary treatment planning needed in order to minimize maternal morbidity and mortality.

Resumo A desordem de adesão placentária é um tipo de placentação anormal que ocorre quando há penetração das vilosidades coriônicas na parede uterina. O acretismo placentário tornou-se mais frequente, principalmente devido às taxas crescentes de cesarianas. A ultrassonografia é a modalidade de imagem de primeira linha para avaliação placentária, apresentando papel limitado nos casos de placenta posterior e achados duvidosos. Nesses casos, a ressonância magnética (RM) está indicada e é bastante eficaz, principalmente para identificar a disseminação extrauterina da placenta em gestantes de alto risco. Neste artigo de revisão apresentamos os dez principais sinais de desordem de adesão placentária pela RM descritos na literatura. Junto a isso, propomos um modelo de relatório estruturado e um questionário direcionado com o intuito de identificar os possíveis fatores de risco da paciente a ser submetida ao exame de RM da placenta, atendendo às expectativas dos especialistas envolvidos no planejamento do tratamento multidisciplinar necessário para minimizar a morbimortalidade materna.

Placenta mórbidamente adherente asociada a malformaciones congénitas: reporte de caso / Morbidly adherent placenta associated with congenital malformations: a case report

INTRODUCCIÓN: Las alteraciones en la placentación son causa importante de morbilidad materna y neonatal y, en ocasiones, de mortalidad. La literatura científica menciona la posible asociación entre acretismo placentario y alteraciones en los parámetros bioquímicos para aneuploidía, sin descripciones de casos en que coincidan estos dos hallazgos. OBJETIVO: Este es un reporte de caso de una gestante con placenta percreta y producto con trisomía 13 REPORTE DE CASO: Gestante de 34 años, gesta 4 cesáreas 2, abortos 1, vivos 2, con embarazo de 20.4 semanas, sin antecedentes de importancia, con hallazgos en ecografía de iii nivel de alteraciones morfológicas en el sistema nervioso central, onfalocele, malformación cardiaca y deformidades en miembros. Con doppler de placenta que evidencia placenta mórbidamente adherida variedad percreta; hallazgos ecográficos confirmados con el estudio anatomopatológico. CONCLUSIONES: La trisomía 13 es una condición genética que debido a las múltiples malformaciones asociadas se considera incompatible con la vida, la placenta mórbidamente adherida se ha asociado con morbimortalidad neonatal y fetal, la no evidencia en la literatura de estas dos condiciones asociadas puede ser debido a la interrupción temprana de las gestaciones en las que se confirma el primer diagnóstico.

BACKGROUND: Alterations in placentation are an important cause of maternal and neonatal morbidity and, sometimes, deaths. The scientific literature mentions the possible association between placental accreta and alterations in the biochemical parameters for aneuploidy, without descriptions of cases in which these two findings coincide. OBJECTIVE: This is a case report of a pregnant woman with placenta percreta and trisomy 13, in which an ultrasound and pathological analysis were made. The use of keywords, in different databases, did not yield information that directly comply with these associations. CASE REPORT: A 34-year-old pregnant woman, G4C2A1V2 with a 20.4-week pregnancy, without significant medical records, with findings at III level ultrasound of morphological alterations of the central nervous system, omphalocele, cardiac malformation and limb deformities. Also, with placental Doppler that evidences morbidly adhered placenta variety percreta; ultrasound findings confirmed with the pathological study. CONCLUSION: The morbidly adhered placenta has been associated with neonatal and fetal mortality, in which some of the identified causes of fetal death are congenital anomalies. This way this case report allows for the first time to describe the association of placental accreta with aneuploidy, type trisomy 13, demonstrated by the morphological alterations of the pathological and karyotype study.

Espectro de placenta acreta

El espectro de placenta acreta (EPA) consiste en una placenta anormalmente adherida al útero que causa hemorragias puerperales severas y sorpresivas, con elevadas cifras de morbimortalidad materna. El tratamiento es quirúrgico y por décadas ha sido la histerectomía la primera opción; sin embargo, en los últimos años aparecen alternativas quirúrgicas para evitar las complicaciones de la histerectomía y preservar la fertilidad de las pacientes. Se realiza una revisión de ensayos controlados, aleatorios y estudios observacionales sobre EPA, con énfasis en lo referente a las alternativas terapéuticas. El manejo quirúrgico del EPA amerita un trabajo multidisciplinario con enfoque preventivo. La histerectomía de emergencia sigue siendo la primera opción en casos de hemorragia severa e inestabilidad hemodinámica, quedando las medidas conservadoras como alternativas válidas, en los casos en que hubo solicitud previa de la paciente, consentimiento informado y ausencia de compromiso hemodinámico. La existencia de múltiples alternativas quirúrgicas conservadoras para el manejo del EPA refleja la ausencia de una técnica ideal y confiable, obligando a afinar nuestro juicio clínico

Placenta accreta spectrum (PAS) is an abnormal placentation that causes unexpected severe postpartum hemorrhage and high morbidity and mortality. Treatment is surgical and hysterectomy has been the first option for decades; however, in the last few years, surgical alternatives try to avoid the severe complications of hysterectomy while preserving woman's fertility. We performed a review of controlled, randomized and observational studies of PAS, with emphasis on therapeutic alternatives. PAS surgical management is a real challenge and merits multidisciplinary and preventive care. Emergency hysterectomy is still the first option in cases of severe hemorrhage and hemodynamic instability, but conservative management is a valid alternative at patient's request, if she gives her informed consent and there is no hemodynamic compromise. The existence of multiple surgical and conservative alternatives in PAS management reflects the absence of an ideal and reliable technique, and requires critical judgment.

Emergency obstetric hysterectomy: a two-year observational study at tertiary care center in Berhampur, Odisha, India

Background: Emergency obstetric hysterectomy is an unequivocal marker of severe maternal morbidity and, in many respects, the treatment of last resort for rupture uterus, severe postpartum hemorrhage (PPH) and other such life-threatening conditions. In no other gynaecological or obstetrical surgery is the surgeon in as much a dilemma as when deciding to resort to an emergency hysterectomy. On one hand it is the last resort to save a mother’s life, and on the other hand, the mother’s reproductive capability is sacrificed. This study is conducted with an aim to determine the frequency, demographic characteristics, indications, and feto-maternal outcomes associated with emergency obstetric hysterectomy in a tertiary care centre.Methods: We conducted a prospective, observational, and analytical study over a period of two years, from September 2017 till September 2019. A total of 56 cases of emergency obstetric hysterectomy (EOH) were studied in the Department of Obstetrics and Gynecology, MKCG Medical College, Berhampur.Results: The incidence of EOH in our study was 12 following vaginal delivery and 44 following caesarean section. The overall incidence was 56 per 21,128 deliveries. Uterine rupture (37.5%) was the most common indication followed by atonic postpartum hemorrhage (25%) and placenta accrete spectrum (10.7%). The most frequent sequelae were febrile morbidity (25.7%) and disseminated intravascular coagulation (21.4%). Maternal mortality was 17.1% whereas perinatal mortality was 51.7%.Conclusions: A balanced approach to EOH can prove to be lifesaving at times when conservative surgical modalities fail and interventional radiology is not immediately available. Our study highlights the place of extirpative surgery in modern obstetrics in the face of rising rates of caesarean section and multiple pregnancies particularly in urban settings in developing countries.

Rotura uterina en el segundo trimestre por acretismo placentario, en gestante con sutura compresiva uterina previa

Postpartum hemorrhage can be a life-threatening condition. Successful approaches have been described using uterine compression sutures to control postpartum hemorrhage, in some cases by a combination of techniques. Procedures to reduce blood loss consist of uterine massage, medical treatment, uterine tamponade and hysterectomy. The uterine compression suture, or B-Lynch technique, has been proposed to control postpartum hemorrhage in such cases of uterine atony, preserving fertility. Although report of complications of this procedure is scarce, the appearance of necrosis, pyometra, uterine rupture and, more recently, exaggerated and abnormal invasion of the placenta (placenta accreta) in a subsequent pregnancy has been described. It is necessary to inform patients on potential complications of the procedure and the need of postoperative follow-up to confirm their absence. We present a case of second trimester uterine rupture due to placenta accreta in a patient with previous uterine compression suture.

La hemorragia posparto puede ser una afección potencialmente mortal. Se han descrito técnicas exitosas que utilizan suturas de compresión uterina para controlar la hemorragia postparto, en algunos casos utilizando una combinación de técnicas. Los procedimientos para reducir la pérdida sanguínea varían desde masaje uterino, tratamiento médico, taponamiento uterino e histerectomía. La sutura compresiva uterina, o técnica de B-Lynch, se ha propuesto para controlar la hemorragia posparto en aquellos casos de atonía uterina, preservando la fertilidad. Aunque el reporte de complicaciones de este procedimiento es escaso, se ha descrito la aparición de necrosis, piometra, rotura uterina y, más recientemente, invasión exagerada y anormal de la placenta (acretismo placentario) en el embarazo subsiguiente. En necesario informar a las pacientes sobre las complicaciones potenciales del procedimiento y la necesidad de seguimiento postoperatorio para confirmar la ausencia de complicaciones. Se presenta un caso de rotura uterina en el segundo trimestre por acretismo placentario en gestante con sutura compresiva uterina previa.

Trastornos del espectro de placenta acreta / Disorders of Placenta Accreta Spectrum

RESUMEN El antecedente de cesáreas es el factor de riesgo más importante en el desarrollo de los trastornos del espectro de placenta acreta. La elevación global del indicador de cesárea ha llevado aparejado un aumento en la incidencia de estos trastornos. Sin embargo, deben considerarse entre los riesgos, otras condiciones antenatales asociadas con un daño quirúrgico menos extenso de la pared uterina, tal es el caso de los legrados. Se realiza una revisión de la literatura sobre el tema de los trastornos del espectro de placenta acreta para profundizar sobre su grave repercusión en el embarazo y se recomienda, como parte de la atención prenatal, la pesquisa de placentación acreta en toda gestante con antecedentes de legrados uterinos. La placenta acreta es casi siempre una condición enteramente iatrogénica y en lo que respecta al aborto, profesionales de la salud y paciente podríamos contribuir a la disminución de su incidencia(AU)

ABSTRACT A history of C-sections is the most important risk factor for the development of placenta accreta spectrum disorders. The global elevation of caesarean section indicator has led to increase the incidence of these disorders. However, other antenatal conditions should be considered among the risks, associated with less extensive surgical damage of the uterine wall, such as curettage. A literature review on the subject of placental accreta spectrum disorders is carried out to deepen on the serious impact on pregnancy. Screening of placenta accreta is recommended in all pregnant women with a history of uterine curettage, as part of prenatal care. Placenta accreta is generally an entirely iatrogenic condition. Health professionals and patients could contribute to the reduction of this condition incidence, in regards to abortion(AU)
