Retrospective analysis of associated factors and adverse pregnancy outcomes of postpartum hemorrhage in the caesarean section of different types of placenta previa / 中华预防医学杂志

Objective: To analyze associated factors and adverse pregnancy outcomes of postpartum hemorrhage in the caesarean section of puerperae with different types of placenta previa. Methods: This retrospective research was a case-control study. Puerperae with cesarean section of placenta previa from January 2019 to December 2020 in Women's Hospital, School of Medicine, Zhejiang University were collected and divided into the<1 000 ml control group or ≥1 000 ml postpartum hemorrhage group according to the amount of blood loss during cesarean section. Differences in continuous variables were analyzed by t-test and categorical variables were analyzed by χ2 test. The risk factors of postpartum hemorrhage were analyzed by logistic multivariate regression. Results: A total of 962 puerperae were enrolled with 773 cases in the control group and 189 cases in the postpartum hemorrhage group. The incidence of gestational weeks, gravidity, parity, induced abortion, placental accreta and preoperative hemoglobin<110 g/L was significantly different between two groups in different types of placenta previa (P<0.001). Logistic multivariate regression model analysis showed that the independent risk factors of postpartum hemorrhage in the caesarean section of low-lying placenta included placental accreta (OR=12.713, 95%CI: 4.296-37.625), preoperative hemoglobin<110 g/L (OR=2.377, 95%CI: 1.062-5.321), and prenatal vaginal bleeding (OR=4.244, 95%CI: 1.865-9.656). The independent risk factors of postpartum hemorrhage in the caesarean section of placenta previa included once induced abortion (OR=2.789, 95%CI:1.189-6.544), induced abortion≥2 (OR=2.843, 95%CI:1.101-7.339), placental accreta (OR=6.079, 95%CI:3.697-9.996), HBsAg positive (OR=3.891, 95%CI:1.385-10.929), and placental attachment to the anterior uterine wall (OR=2.307, 95%CI:1.285-4.142). The rate of postpartum hemorrhage and premature delivery in puerperae with placenta previa was higher than that in puerperae with low-lying placenta (P<0.001). Conclusions: The associated factors of postpartum hemorrhage in puerperae with different types of placenta previa are different. Placenta accreta is the common risk factor of postpartum hemorrhage in puerperae with low-lying placenta and placenta previa.

Intra-abdominal aortic balloon occlusion in the management of placenta percreta / 中华医学杂志(英文版)

BACKGROUND@#Massive bleeding is the main concern for the management of placenta percreta (PP). Intra-abdominal aortic balloon occlusion (IABO) is one method for pelvic devascularization, but the efficacy of IABO is uncertain. This study aims to investigate the outcomes of IABO in PP patients.@*METHODS@#We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015. PP cases with/without the use of IABO were analyzed. Propensity score matching analysis was performed to reduce the effect of selection bias. Postpartum hemorrhage (PPH) and the rate of hysterectomy, as well as neonatal outcomes, were analyzed.@*RESULTS@#One hundred and thirty-two matched pairs of patients were included in the final analysis. Compared with the control group, maternal outcomes, including PPH (68.9% vs. 87.9%, χ2 = 13.984, P < 0.001), hysterectomy (8.3% vs. 65.2%, χ2 = 91.672, P < 0.001), and repeated surgery (1.5% vs. 12.1%, χ2 = 11.686, P = 0.001) were significantly reduced in the IABO group. For neonatal outcomes, Apgar scores at 1 minute (8.67 ± 1.79 vs. 8.53 ± 1.68, t = -0.638, P = 0.947) and 5 minutes (9.43 ± 1.55 vs. 9.53 ± 1.26, t = 0.566, P = 0.293) were not significantly different between the two groups.@*CONCLUSIONS@#IABO can significantly reduce blood loss, hysterectomies, and repeated surgeries. This procedure has not shown harmful effects on neonatal outcomes.

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.

Indicações de cesariana baseadas em evidências: parte II: [revisão] / Evidence-based cesarean section indications: part II: [review]

A alta incidência de cesarianas desnecessárias é motivo de preocupação mundial. Estudos demonstraram que os benefícios conferidos ao feto pela cesariana são pequenos. Além de o procedimento se associar a maiores taxas de mortalidade materna, aproximadamente quatro a cinco vezes maiores que o parto vaginal, está também associado ao aumento da morbidade e mortalidade perinatal. Assim, a decisão para realização de uma cesariana deve ser criteriosa e discutida com a paciente. Realizou-se uma revisão da literatura em busca das melhores evidências disponíveis sobre indicações de cesariana. Foram abordadas algumas indicações, como placenta prévia, descolamento prematuro de placenta, vasa prévia, placenta acreta, infecção por HIV, herpes genital, hepatites e por HPV, condiloma genital, gestação múltipla, prolapso do cordão umbilical, distensão segmentar e ruptura uterina. Observou-se que a cesariana está formalmente indicada em algumas situações particulares, como na placenta prévia total. Em outros casos, pode haver indicação de cesárea intraparto, porém situações como HPV e gemelaridade não representam per se indicações de cesárea. Quando essas são relativas, tanto a mulher como seus familiares devem ser informados, e sua opinião deve ser considerada antes de se decidir pela realização da cesárea.

The increasing rate of unnecessary cesareans is a world preoccupation. Studies demonstrated that fetal benefits by cesarean are small, and the procedure is associated with higher rates of maternal death, 4-5-fold greater in relation with vaginal delivery, and increased perinatal morbidity and mortality. Indeed, the decision for a cesarean delivery should be rigorous and discussed with the patient. A literature review was performed searching the best current evidences evaluable. Indications for cesarean section were analyzed such as placenta praevia, abruptio placentae, vasa praevia, accretism, HIV infection, genital herpes, hepatitis, HPV and condiloma, multiple pregnancy, umbilical cord prolapse, distension and rupture uterine. In special circumstances like total placenta praevia an elective cesarean section is indicated. In other cases, an intrapartum cesarean section should be performed but situations like HPV and multiple pregnancy are not considered indications for cesarean per se. When relative indications for cesarean are present, both women and her family should be informed and their opinion considered when deciding for an operative delivery.

Histerectomía posparto: experiencia de Clínica Las Condes / Postpartum hysterectomy: Clínica Las Condes experience

Objetivo: Analizar la experiencia clínica de pacientes sometidas a histerectomía posparto (HPP). Método: Estudio retrospectivo de la HPP efectuadas en Clínica Las Condes entre enero de 2000 y diciembre de 2009. Resultados: Hubo 15.356 partos con 34 casos de HPP (incidencia de 2,2 histerectomías/1000 partos). La edad materna promedio fue de 36 años; 97 por ciento eran multíparas. La edad gestacional promedio al parto fue 36,1 semanas (rango: 27-40). Causas principales: acretismo placentario (61,8 por ciento), inercia uterina (20,6 por ciento) y rotura uterina (8,8 por ciento). En el 29,4 por ciento se realizó además la ligadura de arterias hipogástricas. Histerectomía total en el 85,3 por ciento. El 91,2 por ciento presentó complicaciones, la más frecuente correspondió a lesión vesical asociada a acretismo placentario (26,5 por ciento). En el postoperatorio inmediato hubo 29 casos de anemia, 10 casos de coagulación intravascular diseminada, 2 casos de hemoperitoneo (reoperadas) y 2 pacientes con choque hipovolémico. Hubo 1 caso de trombosis pelviana, 1 caso de trombosis de vena ovárica y 1 caso de fasceitis necrotizante. Tardíamente hubo 3 casos de depresión, 1 tromboembolismo pulmonar, 1 fístula vésico-vaginal y 1 proceso inflamatorio pelviano. No hubo muertes maternas. Transfusión de sangre y/o hemoderivados en 76,5 por ciento. Hubo 1 mortinato y 2 mortineonatos con un 8,5 por ciento (3/35) de muerte perinatal. Conclusiones: La HPP es una intervención de urgencia que se plantea frente a una hemorragia severa, secundaria a diversas patologías, durante o posterior al parto, asociada frecuentemente con cesárea anterior e inercia uterina.

Objetive: To analyze the clinical experience of peripartum hysterectomy (PH). Method: Retrospective review of women who required PH at Las Condes Clinic since January 2000 to December 2009. Results: In the study period 15,356 patients were delivered with 34 cases of PH (incidence: 2.2/1000 deliveries). The mean age was 36 years old, 97 percent were multiparous. The mean gestational age at delivery was 36.1 weeks (range: 27-40). Causes: placenta accreta (61.8 percent), uterine atony (20.6 percent) and uterine rupture (8.8 percent). In 29.4 percent a bilateral hypogastric ligation was added to the hysterectomy. Total hysterectomy was performed in 85.3 percent of cases. There was at least one complication in 91.2 percent women. The intraopertive bladder injury associated with placenta accreta was the most frequent complication (26.5 percent). Postoperative complications: 29 cases of anemia, 10 cases of disseminated intravascular coagulopathy, 2 hemoperitoneum that required surgical reexploration, 2 cases of hypovolemic shock, 1 case of pelvic thrombosis, 1 case of ovarian vein thrombosis and 1 case of necrotizing fasceitis. Late complications included depression, pulmonary embolism, bladder-vagina fistula and pelvic inflammatory disease. 76.5 percent required transfusion. There were no cases of maternal death with 8.5 percent of perinatal death. Conclusions: PH it is performed in patients with severe bleeding during or after labor and delivery, frequently is associated with serious maternal morbidity. Previous cesarean section with abnormal placental implantation and uterine atony were the most frequent indications.

Emergency obstetric hysterectomy - one year review at Allied hospital, Faisalabad

To study the cases of obstetric hysterectomy performed over a period of one year [Jan. 2008 to Dec. 2008] in a teaching hospital to determine the incidence, indications, associated risk factor and maternal outcome of patients with a view to suggest ways of improving outcome. One year retrospective study of 38 consecutive cases of obstetric hysterectomies performed during the study period were analyzed. Total number of deliveries during the study period were 8988 and 38 emergency obstetric hysterectomies were undertaken; frequency being 0.42%. Only 26.3% women were booked. The most common indication for procedure were uterine rupture, uterine atony and morbidly adherent placenta. Total hysterectomies were undertaken in 73.6% and sub total in 26.3% women. There were 4 [10.5%] maternal deaths. Patients who died were received in critical condition and with massive haemorrhage. Late arrival and non availability of blood because of incooperative attendants were the main factor in maternal mortality. Emergency obstetric hysterectomy remains an essential life saving procedure. Proper antenatal care and early admission in labour ward, training and retraining of traditional birth, attendants, prompt resuscitation and referral of patient in time will go a long way to reduce the incidence of this procedure

Prophylactic Hypogastric Artery Ballooning in a Patient with Complete Placenta Previa and Increta

Abnormal attachment of the placenta (Placenta accreta, increta, and percreta) is an uncommon but potentially lethal cause of maternal mortality from massive postpartum hemorrhage. A 33-yr-old woman, who had been diagnosed with a placenta previa, was referred at 30 weeks gestation. On ultrasound, a complete type of placenta previa and multiple intraplacental lacunae, suggestive of placenta accreta, were noted. For further evaluation of the placenta, pelvis MRI was performed and revealed findings suspicious of a placenta increta. An elective cesarean delivery and subsequent hysterectomy were planned for the patient at 38 weeks gestation. On the day of delivery, endovascular catheters for balloon occlusion were placed within the hypogastric arteries, prior to the cesarean section. In the operating room, immediately after the delivery of the baby, bilateral hypogastric arteries were occluded by inflation of the balloons in the catheters previously placed within. With the placenta retained within the uterus, a total hysterectomy was performed in the usual fashion. The occluding balloons were deflated after closure of the vaginal cuff with hemostasis. The patient had stable vital signs and normal laboratory findings during the recovery period; she was discharged six days after delivery without complications. The final pathology confirmed a placenta increta.

Occlusion of upper genital tract following lower segment caesarean section for placenta praevia

Uterine cavity occlusion following caesarean section for central placenta praevia culminating in haematometra and thereby amenorrhoea is one of the rarest long term complications of lower segment caesarean section. We report a case of 28 year old primigravida with Grade 4 placenta praevia who underwent elective caesarean section at 35 weeks gestation. She presented at Nizwa Hospital, Sultanate of Oman, after 7 months with cyclical lower abdominal pain and amenorrhoea. She was treated by hysteroscopic adhesiolysis and an in utero Foley's catheter. She had complete resolution of her condition within 2 months and resumption of menstrual cycles. Multiple haemostatic sutures at caesarean section for placenta praevia can be an causative factor for such a complication along with other risk factors like multiple caesarean sections, chorioamniotis etc. Recognition of these factors, meticulous surgical technique and appropriate post operative care can effectively prevent it

A multidisciplinary approach to surgical management of placenta previa percreta with bladder invasion: a case report

Placenta previa percreta with bladder invasion occurs rarely. However this disorder has become more common since the increased rate of cesarean deliveries. We present a 26 year old gravida 3, para 2-0-1-2 female with placenta previa, percreta and bladder invasion to stress out the importance of early recognition of this life threatening condition and to point out that the good outcome of this case was mainly due to the multidisciplinary approach chosen during the preoperative and post operative management. The Departments of Obstetrics and Gynecology, Radiology, Anesthesiology, Urology, Neonatology and Pathology were fully involved. A surgical management was chosen since it is the most common and more accepted treatment of placenta previa percreta with bladder invasion.

Cirugía de control de daños: Un concepto aplicable en ginecología y obstetricia / Surgery of damage control: a concept in gynecology and obstetrics

Objetivo: Revisar los casos de cirugía de control de daños en procedimientos ginecoobstétricos en el Hospital Universitario del Valle, Cali, Colombia entre 1997 a 2002.Tipo de estudio: Serie de casos de 28 pacientes ginecoobtétricas. El análisis de las variables cuantitativas se realizó mediante métodos no paramétricos y las variables categóricas con distribución de frecuencias. Resultados: El rango de edad fue entre 13 y 52 años; 5 pacientes eran primigestantes, 18 tenían al menos una cesárea previa. Las indicaciones iniciales para cirugía fueron abruptio placentae, atonia uterina, placenta previa y síndrome Hellp. En todos los casos se realizó cirugía de empaquetamiento y cierre no convencional; el control de daños se identificó en la cirugía inicial en 16 pacientes; 10 de las que tuvieron más de 12 puntos de APACHE fallecieron con diagnóstico de disfunción orgánica múltiple. Comentarios: El control de daños permitió el control de la hemorragia en todos los casos. El retraso en la toma de la decisión, el mayor deterioro fisiológico y el desarrollo de la disfunción orgánica múltiple correlacionaron con mayor probabilidad de morir
