Rudimentary horn pregnancy: clinical analysis of 12 cases and literature review / 中华妇产科杂志

Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

Uterine rupture; An obstetric tragedy still with us. A six year review of cases in a specialist hospital, NorthWest Nigeria

Uterine rupture is a major cause of perinatal and maternal morbidity and mortality, it usually has a devastating outcome if not promptly attended to. The study determined the trends, risk factors, feto-maternal outcomes following uterine rupture as seen at ASYBSH. Method: The study was a retrospective review of cases of uterine rupture managed at the ASYBSH between March 2015 and February 2021. Records of the theatre and labour wards were searched and the folders of patients with uterine rupture were retrieved. Relevant information such as socio-demographic variables, booking status, clinical presentations were retrieved and entered into a structured profoma. Results: Deliveries in the hospital during the period were eleven thousand four hundred and twenty (11,420), out of which one hundred and fifty-six (156) were complicated by uterine rupture giving an overall incidence of 1.36 percent or one in every seventy-four (74) deliveries. Uterine rupture occurred mainly among women of low socio-economic status and high parity. The major predisposing factors were injudicious use of oxytocin (62.8%) prolonged obstructed labour (19.8%), previous caesarean section scar (8.5%), use of misoprostol (5.3%), fundal pressure (2.4%) and unexplained factors (1.2%) Conclusion: Uterine rupture remains a devastating obstetric calamity with a high incidence. Injudicious use of oxytocin, prolonged obstructed labour and previous caesarean section scar were the three leading predisposing factors identified in this study

Attempted vaginal birth after cesarean: assessment of morbidity and predictors of success / Parto tras cesárea anterior: análisis de la morbimortalidad materno-fetal

Objective: Determining the appropriate approach for delivery after previous cesarean is a very controversial issue. Our objective was to establish whether pregnant women with a previous cesarean have an increased maternal and fetal morbidity and mortality after attempting vaginal delivery as well as to determine which factors may influence the achievement of a vaginal birth after cesarean. Materials and methods: A retrospective observational cohort study including 390 patients (196 cesarean group and 194 nulliparous group) was carried out. We compared neonatal and maternal outcomes between groups. Afterward, a multivariate logistic regression was applied for our second objective. Results: There were higher rates of uterine rupture (2% vs. 0%, p: 0.045) and puerperal hemorrhage (9.7% vs. 3.1%, p: 0.008) in the cesarean group and lower vaginal delivery rate (58.2% vs. 77.8%, p < 0.0005). We found that the induced onset of labor (OR = 2.9) and new born weight (OR = 1.0001) were associated with an increased risk of cesarean section. Conclusions: Our findings stress the need for further investigations in this field, which might provide a basis for a better management of patients with a previous cesarean.

Objetivo: Determinar el abordaje adecuado del tipo de parto tras una cesárea previa es un tema muy controvertido. Nuestro objetivo fue establecer si las gestantes con cesárea previa presentan mayor morbimortalidad materna y fetal tras intentar parto vaginal, así como determinar qué factores pueden influir en conseguir un parto vaginal posterior a la cesárea. Material y métodos: Estudio observacional de cohortes retrospectivo incluyendo 390 pacientes (196 con cesárea previa, 194 nulíparas). Comparamos los datos sobre los resultados neonatales y maternos. Posteriormente se aplicó un modelo de regresión logística multivariante. Resultados: Hubo mayores tasas de ruptura uterina (2% vs. 0%; p = 0.045) y hemorragia puerperal (9.7% vs. 3.1%, p: 0.008) en el grupo de cesárea anterior, así como una tasa de parto vaginal mas baja (58.2% vs. 77.8%, p < 0.0005). La inducción del parto (OR = 2,9) y el peso del recién nacido (OR = 1.0001) se asociaron a un mayor riesgo de cesárea. Conclusión: La probabilidad de parto vaginal en estas pacientes disminuye cuanto mayor sea el peso del recién nacido y con partos inducidos.

Parto vaginal exitoso y resultados maternos y perinatales en pacientes con antecedente de cesárea y prueba de trabajo de parto: estudio de corte transversal / Successful vaginal delivery and maternal and perinatal outcomes in patients with a history of cesarean section and labor trial: cross-sectional study

Objetivos: determinar la proporción de parto vaginal exitoso en mujeres con cesárea previa, describir las complicaciones maternas y perinatales, y realizar una aproximación a los factores asociados al parto vaginal. Materiales y métodos: estudio de corte transversal descriptivo. Se incluyeron mujeres con antecedente de un parto por cesárea, con edad gestacional mayor a 24 semanas y fetos únicos vivos que tuvieron prueba de parto vaginal, atendidas en una institución pública de alta complejidad en 2019. Se excluyeron aquellas pacientes con antecedente de más de una cesárea o miomectomía. Muestreo consecutivo. Se midieron variables sociodemográficas, obstétricas, vía del parto y complicaciones maternas y perinatales. Se hace análisis descriptivo y un análisis exploratorio multivariado de los factores asociados al parto vaginal exitoso. Resultados: de 286 gestantes incluidas, el porcentaje de éxito de parto vaginal fue del 74,5 %. Se identificaron complicaciones maternas en el 3,2 % de los partos vaginales y en el 6,8 % de las cesáreas. El 1,3 % de los recién nacidos tuvo alguna complicación. Hubo 2 muertes perinatales. Se encontró asociación entre parto vaginal exitoso y tener antecedente de parto vaginal (OR: 2,7; IC 95 %: 1,15-6,29); puntaje de Bishop mayor de 6 (OR: 2,2; IC 95 %: 1,03-4,56); inicio de trabajo de parto espontáneo (OR: 4,5; IC 95 %: 2,07-9,6); y edad materna menor de 30 años (OR: 2,28; IC 95 %: 1,2-4,2). Conclusiones: el parto vaginal es una opción segura para considerar en pacientes con cesárea anterior, especialmente si inician trabajo de parto espontáneo o han tenido un parto vaginal previamente. Se requieren cohortes prospectivas para confirmar estos hallazgos.

Objectives: To determine the proportion of successful vaginal deliveries in women with prior cesarean section; to describe maternal and perinatal complications; and to examine the factors associated with vaginal delivery. Materials and methods: Descriptive cross-sectional study of women with a history of cesarean delivery, gestational age of more than 24 weeks, singleton live fetuses, with prior vaginal delivery who received care in a high complexity public institution in 2019. Patients with a history of more than one cesarean section or myomectomy were excluded. Consecutive sampling was used. Sociodemographic and obstetric variables, delivery route and maternal and perinatal complications were measured. A descriptive analysis as well as a multivariate exploratory analysis of the factors associated with successful vaginal delivery were carried out. Results: Among 286 pregnant women included, the percentage of successful vaginal deliveries was 74.5 %. Maternal complications were identified in 3.2 % of vaginal delivery cases and in 6.8 % of cesarean births. Complications occurred in 1.3 % of all live neonates; there were 2 perinatal deaths. An association was found between successful vaginal delivery and a history of prior vaginal delivery (OR: 2.7; 95 % CI: 1.15-6.29); a Bishop score greater than 6 (OR: 2.2; 95 % CI: 1.03-4.56); spontaneous labor initiation (OR: 4.5; IC 95 % CI: 2.07-9.6); and maternal age under 30 years (OR:2.28; 95 % CI: 1.2-4.2). Conclusions: Vaginal delivery is a safe option to consider in patients with prior cesarean section, in particular in cases of spontaneous labor initiation or prior vaginal delivery. Prospective cohorts are needed in order to confirm these findings.

Rotura uterina: da suspeita ao tratamento / Uterine rupture: from suspicion to treatment

A rotura uterina durante a gravidez ou trabalho de parto é uma grave complicação obstétrica ainda responsável por elevada morbimortalidade materna e perinatal. É importante o diagnóstico diferencial de outras hemorragias da segunda metade da gravidez, como o descolamento prematuro da placenta e a placenta prévia. O diagnóstico é feito baseado em uma associação de sinais bem comuns da rotura uterina. O tratamento sempre é cirúrgico, mas varia de acordo com a classificação da emergência. A prevenção é realizada por meio da atenção obstétrica cuidadosa e com implementação das boas práticas de assistência ao parto.(AU)

Uterine rupture during pregnancy or labor is a serious obstetric complication still responsible for high maternal and perinatal morbidity and mortality. Differential diagnosis of other hemorrhages in the second half of pregnancy, such as placental abruption and placenta previa, is important. The diagnosis is made based on an association of very common signs of uterine rupture. Treatment is always surgical but varies according to the classification of the emergency. Prevention is carried out through careful obstetric care and the implementation of good childbirth care practices.(AU)

Associação entre a técnica de fechamento uterino na cesárea e a istmocele: uma visão global / Association between uterine closure technique after cesarean and isthmocele: an overview

A istmocele (ou "defeito cicatricial de cesariana") é uma alteração anatômica na parede uterina responsável por formar um "nicho", que é visualizado como uma área hipoecoica por histerografia ou por outros métodos de imagem, devido a uma cicatrização inapropriada de uma cesárea anterior. Essa modificação leva a complicações ginecológicas e obstétricas. Este estudo pretendeu analisar, entre os fatores de risco, a relação da istmocele com a técnica de fechamento uterino, comparando a sutura em camada simples com a dupla. Foi realizada uma revisão de literatura por meio de pesquisa bibliográfica em diferentes bases de dados eletrônicos. Foram encontrados 31 artigos, todavia apenas 13 estudos foram incluídos no presente estudo após avaliação criteriosa. A técnica de fechamento uterino é um dos fatores de risco possível de prevenir, sendo que a sutura em camada simples é associada a maior chance de se desenvolver a istmocele. A sutura de camada simples (ancorada) incluindo o endométrio está relacionada a menor espessura miometrial residual, associada a probabilidade de ruptura uterina e a istmocele, que a camada dupla não ancorada com a exclusão do endométrio.(AU)

The isthmocele is an anatomical alteration in the uterine wall responsible for forming a "niche", which is visualized as a hypoechoic area by hysterography or other imaging methods, due to inappropriate healing of a previous cesarean section. This modification leads to gynecological and obstetric complications. This study aimed to analyze among the risk factors the relation of isthmocele and the uterine closure technique comparing the single- and double-layer suture. It was conducted an electronic based search in different electronic databases. The research led to the retrieval of 31 articles; however only 13 studies were included in the present research after careful reading. The uterine closure technique is one of the possible risk factors to be modified; the single-layer suture is associated with a greater chance of developing isthmocele. The locked single-layer suture including the decidua is related to the decreased residual myometrial thickness, associated with the likelihood of uterine rupture and the isthmocele, than the double-layer unlocked excluding the decidua.(AU)

Facteurs de risque et prise en charge de la rupture utérine dans une structure de 1ere référence du Mali: cas du district sanitaire de Bougouni / Risk factors and management of uterine rupture in a 1st reference structure in Mali: case of the Bougouni health district

L'objectif était d'évaluer les facteurs de risque de la RU et de proposer les aspects thérapeutiques. Matériels et méthodes : Nous avons réalisé une étude cas-témoins au centre de santé de Référence de Bougouni en 2019. Résultats : De janvier au 31 décembre 2019; sur 1161 accouchements 43 RU ont été enregistrées soit 3,7% correspondant à une RU pour 27 accouchements. Les patientes de 35 ans et plus ont été plus touchée par la RU (44,2%) avec ORaIC95%= 6,3 [1,5 - 26,3]. Les évacuations obstétricales avaient un ORaIC95%=25,6 [7,8- 83,7]. La totalité des patientes étaient des femmes au foyer (97,7%) des cas versus (82,3%) des témoins avec ORaIC95%= 8,9 (1,1-69). Les Paucipares et multipares avaient respectivement un ORaIC95%= 6,2 [1,8 - 20,3] et 4,1[1,3 - 12,9]. La cicatrice utérine (20,9%) des cas contre 8,1 % les témoins avait un ORaIC95%= 2,9 [1,1 - 8,7]. En effet l'absence de CPN étaient un facteur de risque, ORaIC95%= 3,0 [1,3 ­ 6,9]. Le délai de la RU était ˂ 6 heures chez 95%. En effet 34 RU complètes (79,1%) et 9 RU incomplètes (20,9%) ont été notées. Seulement 2,3 % des cas avaient accouché par voie basse. Le traitement de la RU reposait sur la chirurgie (100%) complétée par celui du choc (51,2%) des cas et de l'infection (100%) des cas. Conclusion: La RU est fréquente dans nos pays sous médicalisés. Sa prévention efficace passe par des stratégies visant à agir sur les facteurs de risque

The objective was to assess the risk factors for and to suggest therapeutic aspects. Materials and methods: We carried out a case-control study at the Bougouni Reference health center in 2019. Results: From January to December 31, 2019; out of 1161 deliveries, 43 uterine rupture were recorded, 3.7% corresponding to one uterine rupture for 27 deliveries. Patients 35 years and older were more affected by uterine rupture (44.2%) with ORaIC95% = 6.3 [1.5 - 26.3]. Obstetric evacuations had an ORaIC95% = 25.6 [7.8-83.7]. All of the patients were housewives (97.7%) versus (82.3%) controls with ORaIC95% = 8.9 (1.1-69). Pauciparous and multiparous had an ORaIC95% = 6.2 [1.8 - 20.3] and 4.1 [1.3 - 12.9], respectively. The uterine scar (20.9%) of cases versus 8.1% of controls had a 95% ORaIC95% = 2.9 [1.1 - 8.7]. Indeed the absence of ANC was a risk factor, ORaIC95% = 3.0 [1.3 - 6.9]. The time to uterine rupture was ˂ 6 hours in 95%. In fact 34 complete uterine rupture (79.1%) and 9 incomplete uterine rupture (20.9) were noted. Only 2.3% of cases gave birth vaginally. Treatment of uterine rupture was based on surgery (100%) supplemented by shock (51.2%) of cases and infection (100%) of cases. Conclusion: Uterine rupture is common in our countries under medical care. Its effective prevention involves strategies aimed at acting on risk factors.

Risk Factors Associated with Uterine Rupture and Dehiscence: A Cross-Sectional Canadian Study / Fatores de risco associados à ruptura uterina e deiscência: Um estudo transversal canadense

Abstract Objective To compare maternal and perinatal risk factors associated with complete uterine rupture and uterine dehiscence. Methods Cross-sectional study of patients with uterine rupture/dehiscence from January 1998 to December 2017 (30 years) admitted at the Labor and Delivery Unit of a tertiary teaching hospital in Canada. Results There were 174 (0.1%) cases of uterine disruption (29 ruptures and 145 cases of dehiscence) out of 169,356 deliveries. There were associations between dehiscence and multiparity (odds ratio [OR]: 3.2; p=0.02), elevated maternal body mass index (BMI; OR: 3.4; p=0.02), attempt of vaginal birth after a cesarian section (OR: 2.9; p=0.05) and 5-minute low Apgar score (OR: 5.9; p<0.001). Uterine rupture was associated with preterm deliveries (36.5 ± 4.9 versus 38.2 ± 2.9; p=0.006), postpartum hemorrhage (OR: 13.9; p<0.001), hysterectomy (OR: 23.0; p=0.002), and stillbirth (OR: 8.2; p<0.001). There were no associations between uterine rupture and maternal age, gestational age, onset of labor, spontaneous or artificial rupture of membranes, use of oxytocin, type of uterine incision, and birthweight. Conclusion This large cohort demonstrated that there are different risk factors associated with either uterine rupture or dehiscence. Uterine rupture still represents a great threat to fetal-maternal health and, differently from the common belief, uterine dehiscence can also compromise perinatal outcomes.

Resumo Objetivo Comparar os fatores de risco maternos e perinatais associados à ruptura uterina completa e deiscência uterina. Métodos Estudo transversal de pacientes com ruptura/deiscência uterina no período de janeiro de 1998 a dezembro de 2017 (30 anos) internadas na Unidade de Parto de um hospital universitário terciário no Canadá. Resultados Ocorreram 174 (0,1%) casos de transtorno uterino (29 rupturas e 145 deiscências) em 169.356 partos. Houve associações entre deiscência e multiparidade (razão de chances [RC]: 3,2; p=0,02), índice demassa corporal (IMC)materno elevado (RC: 3,4; p=0,02), tentativa de parto vaginal após cesariana (RC: 2,9; p=0,05) e baixa pontuação Apgar em 5minutos (RC: 5,9; p<0,001). A ruptura uterina foi associada a partos prematuros (36,5 ± 4,9 versus 38,2 ± 2,9; p=0,006), hemorragia pós-parto (RC: 13,9; p<0,001), histerectomia (RC: 23,0; p=0,002) e natimorto (RC: 8,2; p<0,001). Não houve associação entre ruptura uterina e idade materna, idade gestacional, início do trabalho de parto, ruptura espontânea ou artificial de membranas, uso de ocitocina, tipo de incisão uterina e peso ao nascer. Conclusão Esta grande coorte demonstrou que existem diferentes fatores de risco associados à ruptura ou à deiscência uterina. A ruptura uterina ainda representa uma grande ameaça à saúde materno-fetal e, diferentemente da crença comum, a deiscência uterina também pode comprometer os desfechos perinatais.

Investigación de incidencia y complicaciones de histerectomía de emergencia en periparto / Investigation of Incidence and Complications of Emergency peripartum hysterectomy

Introducción: La histerectomía periparto de emergencia es una cirugía de alto riesgo, que se realiza mayoritariamente después de un parto vaginal o cesárea. Dada la importancia de las complicaciones y la mortalidad de las embarazadas para el sistema de salud, el presente estudio tuvo como objetivo investigar la incidencia y las complicaciones de la histerectomía periparto de emergencia en los hospitales generales y docentes de la Universidad de Ciencias Médicas de Zahedan. Materiales y Métodos: En este estudio descriptivo-analítico transversal, luego de obtener la aprobación del Comité de Ética, se investigó la historia clínica de las pacientes con histerectomía periparto de emergencia ingresadas en el hospital Ali ibn Abitaleb de Zahedan para la interrupción del embarazo durante 2017-2018. fueron estudiados. Después de evaluar las características demográficas, incluida la edad, la educación y la ocupación, se investigaron las causas y las complicaciones de la histerectomía de emergencia. Finalmente, los datos fueron analizados por el software SPSS.Resultados: De 2438 casos, se investigaron 50 casos de histerectomía. La edad media de las madres y el número medio de embarazos fue de 31,06 ± 5,21 y 5,72 ± 2,31, respectivamente. En este estudio, se registraron 35 cesáreas (70%) y 15 partos vaginales normales (30%), y solo el 2% condujo a una histerectomía de emergencia. Las causas más comunes de histerectomía de emergencia incluyeron placenta accreta (28%), atonía uterina (24%) y rotura uterina (20%). Las complicaciones también incluyeron fiebre (24%), coagulopatía (14%) e infección de la herida (12%). Conclusión: la placenta accreta y la atonía uterina son las causas más importantes de histerectomía. Las complicaciones más comunes de la histerectomía de emergencia son fiebre, coagulopatía e infecciones de heridas. Una disminución en el parto por cesárea electiva y un mayor fomento del parto vaginal natural podrían reducir significativamente la incidencia de histerectomía periparto y la mortalidad materna

Introduction: The emergency peripartum hysterectomy is a high-risk surgery, which is mostly performed after vaginal delivery or Caesarean section. Given the importance of complications and mortality of pregnant mothers for the health system, the present study aimed to investigate the incidence and complications of emergency peripartum hysterectomy in general and teaching hospitals of Zahedan University of Medical Sciences. Materials and Methods: In this cross-sectional descriptive-analytic study, after obtaining the Ethics Committee approval, the medical record of patients with emergency peripartum hysterectomy admitted to Ali ibn Abitaleb hospital of Zahedan for pregnancy termination during 2017-2018 were investigated. were studied. After evaluating demographic characteristics, including age, education, and occupation, causes, and complications of emergency hysterectomy were investigated. Finally, data were analyzed by SPSS software. Results: Out of 2438 cases, 50 cases of hysterectomy were investigated. The mean age of mothers and the average number of pregnancies was 31.06±5.21 and 5.72±2.31, respectively. In this study, 35 caesarean sections (70%) and 15 normal vaginal delivery (30%) were recorded, with only 2% leading to emergency hysterectomy. The most common causes of emergency hysterectomy included placenta accreta (28%), uterine atony (24%), and uterine rupture (20%). The complications also included fever (24%), coagulopathy (14%), and wound infection (12%). Conclusion: Placenta accreta and uterine atony are the most important causes of hysterectomy. The most common complications of emergency hysterectomy are fever, coagulopathy, and wound infections. A decrease in elective caesarean delivery and further encouraging to natural vaginal delivery could significantly reduce the incidence of peripartum hysterectomy and maternal mortality

A scary complication: single-center study on management and outcome of cesarean scar pregnancy

Abstract A cesarean scar pregnancy (CSP) is a scary and life-threatening complication of cesarean section (CS). Nevertheless, the incidence of CS is constantly growing. The CSP incidence is 0,15% of pregnancies after CS which represents 6,1% of all ectopic pregnancies in women with condition after CS. Therefore, it should be more present in the clinical daily routine. From mild nonspecific symptoms to hypovolemic shock, diagnosis and therapy must be performed quickly. With the progressive growth of the scar pregnancy, a uterine rupture involves the risk of severe bleeding, and an emergency hysterectomy could be necessary. Prolongation of pregnancy has been successful only in a few cases.We report 11 cases from our hospital in the past 10 years. In the discussion, treatment options of this complication with an increasing incidence, which is associated with serious morbidity and mortality, are presented based on the current literature. Treatment options include drug therapy, but also surgical or combined procedures with radiological intervention.

Reporte de caso: ruptura uterina durante trabajo de parto, en útero sin cicatriz previa / Case review: uterine rupture during labor, in uterus without previous scar

Resumen La ruptura uterina es una complicación obstétrica poco frecuente con una alta morbilidad y mortalidad materna e infantil. El diagnóstico precoz y el tratamiento inmediato son factores pronósticos importantes tanto para la madre como para el feto. Se presenta el caso de una paciente multigestante, con alto riesgo por diabetes gestacional compensada y déficit de proteína S sin manejo, con embarazo a término y adecuado control prenatal, que ingresa hemodinámicamente estable, con cambios cervicales iniciales, feto en presentación longitudinal, cefálico con monitoreo fetal categoría ACOG 1 para conducción del trabajo de parto, y presenta ruptura uterina espontánea, dando lugar a un hemoperitoneo materno y sufrimiento fetal agudo con posterior tratamiento quirúrgico de urgencia mediante una cesárea e histerectomía, por atonía uterina sin control del sangrado con maniobras farmacológicas. Este caso es muy significativo por la falta de factores de riesgo y su presentación clínica atípica, tanto en síntomas y signos como en la ubicación de la ruptura. MÉD. UIS.2021;34(1): 107-12.

Abstract Uterine rupture is a rare obstetric complication with high maternal and infant morbidity and mortality. Early diagnosis and immediate treatment are important prognostic factors for both mother and fetus. The study presents the case of a multigravida patient, with high risk for compensated gestational diabetes, and uncontrolled protein S deficiency. The patient, who was full-term and had adequate prenatal control, was admitted hemodynamically stable, with initial cervical changes, fetus in longitudinal presentation, andcephalic with monitoring category ACOG 1. The patient spontaneous uterine rupture, which leads to maternal hemoperitoneum and acute fetal distress. Cesarean section and hysterectomy were performed as emergency surgical treatments due to uterine atony without bleeding control with pharmacological maneuvers. This case is great significance due to the lack of risk factors and the atypical clinical presentation, evidenced in the signs and symptoms and the rupture's location. MÉD.UIS.2021;34(1): 107-12.

A propósito de un caso: presentación atípica de rotura uterina / A case report: unusual presentation of uterine rupture

RESUMEN La rotura del útero gestante se define como una solución de continuidad patológica de la pared uterina, situada con mayor frecuencia en el segmento inferior. La rotura de un útero intacto es muy rara, su incidencia está estimada entre 1/5700 y 1/20000 embarazos. Su prevalencia ha aumentado dado el incremento de parto vaginal con cesárea anterior. Actualmente oscila entre el 0.3 y el 1 %, siendo mayor en mujeres en las que tiene lugar un intento de parto vaginal tras cesárea (0,78%) que en aquellas en las que se lleva a cabo una cesárea electiva (0,22%). En cuanto a su diagnóstico, suele ser precoz, dada la clínica de gravedad con la que debutan. En este caso se presenta una evolución atípica de rotura uterina, donde la paciente se mantiene asintomática hasta que acude a urgencias cinco días después del parto con fiebre y dolor abdominal; gracias a la ecografía abdominal y trans-vaginal se pudo establecer rápidamente el diagnóstico y así proceder a su inmediata reparación quirúrgica.

ABSTRACT Rupture of the pregnant uterus is defined as a solution of pathological continuity of the uterine wall, most often located in the lower segment. The rupture of an intact uterus is very rare, its incidence is estimated between 1/5700 and 1/20000 pregnancies. Its prevalence has increased given the increase in vaginal delivery with previous caesarean section. Currently, it ranges between 0.3 and 1%, being higher in women with a vaginal delivery after caesarean section (0.78%) than in those who undergo an elective caesarean section (0.22%). Their diagnosis is usually early given by the severity of the debut. In this case, there is an atypical evolution of uterine rupture where the patient remains asymptomatic until she goes to the emergency room five days after delivery with fever and abdominal pain; Because of the abdominal and transvaginal ultrasound, the diagnosis could be quickly established and thus proceed to immediate surgical repair.

Ruptura uterina em primípara: relato de caso / Uterine rupture in primiparous: case report

Introdução: A ruptura uterina é uma complicação grave, devido ao risco de morte materna e perinatal. Em países desenvolvidos, essa complicação obstétrica afeta 3,5/1.000 mulheres com cesárea anterior e 6/10.000 grávidas sem antecedentes da operação, sendo a incisão cesariana prévia a etiologia principal. Relato de Caso: Gestante, 38 anos, G1P0A0, com idade gestacional de 35 semanas e 5 dias, deu entrada na maternidade em trabalho de parto prematuro. Ao exame físico apresentando 3 metrossístoles em 10min/30" 30" 35", colo uterino amolecido e fino, com dilatação de 3 cm, exame especular com presença de líquido amniótico claro, bolsa rota há 6 horas e pequeno sangramento há 20 minutos. Foi indicado parto cesáreo devido ao histórico de luxação de quadril. O diagnóstico de ruptura uterina foi realizado durante o parto operatório, com visualização de partes fetais. O caso teve evolução benigna para a m ãe e o recém-nascido, sem a ocorrência de complicações ou sequelas, ambos tiveram alta hospitalar em perfeitas condições de saúde. Discussão: Configurou-se uma ruptura uterina completa espontânea no terceiro trimestre gestacional, sem quaisquer fatores de risco subjacentes identificáveis, exceto pela idade materna avançada (maior que 35 anos). Conclusão: Este relato contribui para um número limitado de ocorrências descritas que envolvem ruptura espontânea de um útero sem cicatriz prévia em uma paciente primigesta.

Introduction: Uterine rupture is a serious complication, due to the risk of maternal and perinatal death. In developed countries, this obstetric complication affects 3.5/1,000 women with previous cesarean section and 6/10,000 pregnant women with no story of the operation, with the previous cesarean section being the main etiology. Case Report: Pregnant woman, 38 years old, G1P0A0, with a gestational age of 35 weeks and 5 days, was admitted to the maternity ward in premature labor. At the physical examination reinforced 3 metrosystoles in 10min/30" 30" 35", soft and thin cervix, with 3cm dilation, specular examination with the presence of clear liquid with lumps, broken bag for 6 hours and minor bleeding for 20 minutes. Cesarean delivery is indicated due to a story of hip dislocation. The diagnosis of uterine rupture was performed during operative delivery, with visualization of fetal parts. The case had a benign evolution for the mother and the newborn, without the occurrence of complications or sequelae, both were discharged from hospital in perfect health conditions. Discussion: A complete spontaneous uterine rupture occurred in the third trimester of pregnancy, without any identifiable underlying risk factors, except for advanced maternal age (over 35 years). Conclusion: This report contributes to a limited number of previous events that involve spontaneous rupture of a uterus without previous scarring in a primigravid patient.

Uterine scar rupture at the site of the placenta accreta presenting as a case of sudden death

Uterine rupture during pregnancy is a known complication of placenta accreta. This paper presents a case of sudden maternal death in the 27th week of gestation due to a ruptured uterine scar at the site of placenta accreta with a short inter-pregnancy period of 6 months with previous two C-sections. Autopsy findings revealed a massive hemoperitoneum and a thinned out anterolateral uterine wall. Internal examination revealed clotted and fluid blood in the peritoneal cavity with rupture of the anterior uterine wall at the site of the placenta accreta in a healed cesarean section scar. Placenta accreta is a rare complication of pregnancy. However, it is becoming more frequent and a significant risk factor with the increasing rate of C-section.

INVESTIGACIÓN DE LA INCIDENCIA Y COMPLICACIONES DEL PERIPARTO DE EMERGENCIA HISTERECTOMÍA / 9 INVESTIGATION OF INCIDENCE AND COMPLICATIONS OF EMERGENCY PERIPARTUM HYSTERECTOMY

Introduction: The emergency peripartum hysterectomy is a high-risk surgery, which is mostly performed after vaginal delivery or Cesarean section. Given the importance of complications and mortality of pregnant mothers for the health system, the present study aimed to investigate the incidence and complications of emergency peripartum hysterectomy in general and teaching hospitals of Zahedan University of Medical Sciences. Materials and Methods: In this cross-sectional descriptive-analytic study, after obtaining the Ethics Committee approval, the medical record of patients with emergency peripartum hysterectomy admitted to Ali ibn Abitaleb hospital of Zahedan for pregnancy termination during 2017-2018 were investigated. were studied. After evaluating demographic characteristics, including age, education, and occupation, causes, and complications of emergency hysterectomy were investigated. Finally, data were analyzed by SPSS software. Results: Out of 2438 cases, 50 cases of hysterectomy were investigated. The mean age of mothers and the average number of pregnancies was 31.06±5.21 and 5.72±2.31, respectively. In this study, 35 cesarean sections (70%) and 15 normal vaginal delivery (30%) were recorded, with only 2% leading to emergency hysterectomy. The most common causes of emergency hysterectomy included placenta accreta (28%), uterine atony (24%), and uterine rupture (20%). The complications also included fever (24%), coagulopathy (14%), and wound infection (12%). Conclusion: Placenta accreta and uterine atony are the most important causes of hysterectomy. The most common complications of emergency hysterectomy are fever, coagulopathy, and wound infections. A decrease in elective caesarean delivery and further encouraging to natural vaginal delivery could significantly reduce the incidence of peripartum hysterectomy and maternal mortality.

Hemoperitoneo masivo como presentación de un caso de percretismo placentario / Massive hemoperitoneum as a rare presentation of placental percretism

El acretismo placentario se define como la invasión anómala de la placenta al miometrio, denominado percretismo en su forma más severa. En la actualidad se describe la coexistencia de placenta previa con cicatriz de cesárea, como el principal factor de riesgo. Siendo esta última variable la que explica su incidencia al alza en los últimos años. El pronóstico depende mayoritariamente del grado de adherencia, del diagnóstico prenatal y del adecuado manejo multidisciplinario. Con el objetivo de mostrar una presentación poco frecuente de percretismno placentario se presenta a continuación un caso clínico sin diagnóstico prenatal con requerimiento de cirugía de urgencia y su respectivo outcome.

Placental acretism is defined as an abnormal invasion of the placenta to the myometrium, it's most severe presentation being placenta percreta. The main risk factor for this disease is the coexistence of placenta previa and previous cesarean section. Its incidence has been progressively rising, mainly because of the increase in cesarean sections. Extent of adherence, prenatal vs intra surgery diagnosis, and multidisciplinary management are accountable for the prognosis of placental acretism. A case report with no prenatal diagnosis, which required emergency surgery, and its outcome is presented.

Abdomen agudo por coriocarcinoma accidentado. Reporte de un caso clínico / Acute abdomen by accidented coriocarcinoma. Report of a clinical case

Introducción: El coriocarcinoma es una neoplasia gestacional trofoblástica maligna que puede ocurrir después de una mola hidatiforme, embarazo ectópico, aborto e incluso de un embarazo normal. Se trata de una patología poco frecuente que en ocasiones puede pasar desapercibida. Entre las complicaciones clínicas se destaca la metástasis, pero es excepcional la ruptura uterina, siendo esta la que se presenta en el presente caso denotando la importancia del seguimiento. Presentación de caso: Paciente femenina de 49 años que presenta dolor en hipogastrio y vómito, tiene antecedente de mola hidatiforme no controlada. Examen complementario muestra beta-gonadotropina coriónica humana (B-HCG) cualitativa positiva y culdoscentesis positiva. Se realiza tratamiento quirúrgico por laparotomía exploratoria evidenciándose hemoperitoneo más tumor que perfora útero. Se realiza histerectomía abdominal total. Se confirma diagnóstico presuntivo a través de estudio histopatológico que determina coriocarcinoma. Paciente no continua con tratamiento conociéndose posteriormente su deceso. Conclusiones: Se presenta este caso por ser una patología infrecuente con una complicación poco habitual como es la ruptura uterina por coriocarcinoma, al ser considerada una rareza su importancia radica en el diagnóstico oportuno y adecuado seguimiento del caso.

A seven-year review of emergency obstetric hysterectomy in a Nigerian tertiary institution

Background:Extirpativeuterinesurgeries for near-miss events are usually thelast resort when other conservative measures fail.Emergency obstetric hysterectomy(EOH)may still have a significant role where there are limited options.Objectives:To determine the prevalenceof EOH, theassociatedfactorsandthe foeto-maternal outcomeat the Olabisi Onabanjo University Teaching Hospital, Nigeria.Methods:This was a retrospective observational study covering sevenyears (January 2010 to December 2016). The case records of patients who hadEOH during this period were retrieved for data extraction. Results:There were 5,608 deliveries and 31 cases requiringEOH giving aprevalence rateof31/5,608(0.55%). The mean age of the patients was 30.3±4.2years, whilethe mean gestational age at delivery was 36.3±5.1 weeks. Most of thepatients16/25(64.0%) were of higher parity (>3), and12/25(48%)of the patients were within the age bracket of 25-34 years. Subtotal hysterectomywas the most common procedure(18; 72.0%), andruptured uterus wasthe main indication for EOH (40.0%). The twomost common interventions that were critical to survival includedmassive blood transfusion (24.0%)andIntensive Care Unit admission (20%).Two (8%)maternal deathsand 58.3% perinatal mortality wererecorded.Conclusion:EOH is still relatively frequently performedat this centredue tothehigh incidence of a ruptured uterus. Effortsshould be made to increase the proportion of deliveries attended by skilled personnel and improvethe capacity of lower levelhospitals for comprehensive emergency obstetric care

Obstetric outcome of induction of labor using prostaglandin gel in patients with previous one cesarean section

OBJECTIVE: After globally acceptance of planned vaginal birth after cesarean section (VBAC), the mode of induction is still a matter of debate and requires further discussion. We aimed to study obstetric outcomes in post-cesarean patients undergoing induction of labor with prostaglandin gel compared with patients who developed spontaneous labor pains. METHODS: All patients at 34 weeks or more of gestation with previous one cesarean section eligible for trial of labor after cesarean section admitted in a labor room within one year were divided in 2 groups. Group one consisted of patients who experienced the spontaneous onset of labor pains and group 2 consisted of patients who underwent induction of labor with prostaglandin gel. They were analyzed for maternofetal outcomes. Descriptive statistics, independent sample t-test, and chi-square test were applied using SPSS 20 software for statistical analysis. RESULTS: Both groups were comparable in maternal age, parity, and fetal weight, but different in bishop score, mode of delivery, and neonatal outcome. Admisson bishop score was 6.61±2.51 in group 1 and 3.15±1.27 in group 2 (P<0.005). In the patients who experienced spontaneous labor, 86.82% had successful VBAC. In the patients with induced labor, 64.34% had successful VBAC with an average dose of gel of 1.65±0.75. Both groups had one case each of uterine rupture. The neonatal intensive care unit admission rate was 4.1% in group one and 10.4% in group 2. CONCLUSION: This study reflects that supervised labor induction with prostaglandin gel in previous one cesarean section patients is a safe and effective option.
