简介：AbstractPosterior placenta accreta spectrum (PAS) disorders are infrequent but potentially associated with significant maternal mortality and morbidity, especially if not diagnosed prenatally. Analysis of published literature is problematic since most experiences included only a few cases. Knowledge of the risk factors associated with posterior PAS is crucial to identifying mothers at higher risk and ask for high sensitivity studies. Ultrasound has poor diagnostic accuracy in detecting posterior PAS, while magnetic resonance imaging better delineates the posterior uterine wall. In comparison, prenatal imaging’s diagnostic performance in detecting posterior PAS is significantly lower than anterior placenta invasion. Management of posterior PAS depends on several factors, including maternal hemodynamic status, available resources, clinical presentation, and invasion severity. For accreta or increta cases, a compression suture is habitually enough to perform hemostasis. Nevertheless, organ involvement habitually requires a multidisciplinary team with the assistant of a general or coloproctology surgeon. The present article aims to update the risk factors, prenatal diagnosis, and surgical management of pregnancies complicated by posterior PAS.

简介：AbstractPlacenta accreta spectrum is a complication of pregnancy, which poses a great risk on maternal health. Historically, hysterectomy was the modality of treatment of such condition, but an approach towards a more conservative management has been in the light recently. This includes several methods with varying rates of success and complications. Expectant management is effective in up to 78%-80% of the cases. The extirpative method is associated with a high risk of postpartum hemorrhage. The success of the one-step conservative procedure depends on the degree of placental invasion, and the triple-P procedure appears to be successful but requires and interdisciplinary approach. Adjuvant treatment options can be tailored according to individual cases, and these include methotrexate injection, uterine devascularization and hysteroscopic resection of retained placental tissues. Follow up after conservative management is crucial to detect complications early, and it can be done by ultrasound, Doppler examination, and trending β human chorionic gonadotropin levels. Conservative management of placenta accreta spectrum can preserve future fertility but should only be done in hospitals with enough experience as it carries a high risk of maternal complications. In the future, more research should be directed to achieve clear guidelines regarding this topic.

简介：AbstractObjective:To explore the risk factors and pregnancy outcomes in women with a history of cesarean section complicated by placenta accreta (PA).Methods:This case-control study included clinical data from singleton mothers with a history of cesarean section in 11 public tertiary hospitals in seven provinces of China between January 2017 and December 2017. According to the intraoperative findings after delivery, the study population was divided into PA and non-PA groups. We compared the pregnancy outcomes between the two groups, used multivariate logistic regression to analyze the risk factors for placental accreta.Results:For this study we included 11,074 pregnant women with a history of cesarean section; and of these, 869 cases were in the PA group and 10,205 cases were in the non-PA group. Compared with the non-PA group, the probability of postpartum hemorrhage (236/10,205, 2.31% vs. 283/869, 32.57%), severe postpartum hemorrhage (89/10,205, 0.87% vs. 186/869, 21.75%), diffuse intravascular coagulation (3/10,205, 0.03% vs. 4/869, 0.46%), puerperal infection (33/10,205, 0.32% vs. 12/869, 1.38%), intraoperative bladder injury (1/10,205, 0.01% vs. 16/869, 1.84%), hysterectomy (130/10,205, 1.27% vs. 59/869, 6.79%), and blood transfusion (328/10,205,3.21 % vs. 231/869,26.58%) was significantly increased in the PA group (P < 0.05). At the same time, the neonatal birth weight (3250.00 (2950.00-3520.00) g vs. 2920.00 (2530.00-3250.00) g), the probability of neonatal comorbidities (245/10,205, 2.40% vs. 61/869, 7.02%), and the rate of neonatal intensive care unit admission (817/10,205, 8.01% vs. 210/869, 24.17%) also increased significantly (P < 0.05). Weight (odds ratio (OR)= 1.03, 95% confidence interval (CI): 1.01-1.05)), parity (OR= 1.18, 95%CI: 1.03-1.34), number of miscarriages (OR= 1.31, 95%CI: 1.17-1.47), number of previous cesarean sections (OR= 2.57, 95%CI: 2.02-3.26), history of premature rupture of membrane (OR= 1.61, 95%CI: 1.32-1.96), previous cesarean-section transverse incisions (OR= 1.38, 95%CI: 1.12-1.69), history of placenta previa (OR= 2.44,95%CI: 1.50-3.96), and the combination of prenatal hemorrhage (OR= 9.95,95%CI: 8.42-11.75) and placenta previa (OR= 91.74, 95%CI: 74.11-113.56) were all independent risk factors for PA.Conclusion:There was an increased risk of adverse outcomes in pregnancies complicated by PA in women with a history of cesarean section, and this required close clinical attention. Weight before pregnancy, parity, number of miscarriages, number of previous cesarean sections, history of premature rupture of membranes, past transverse incisions in cesarean sections, a history of placenta previa, prenatal hemorrhage, and placenta previa were independent risk factors for pregnancies complicated with PA in women with a history of cesarean section. These independent risk factors showed a high value in predicting the risk for placentab accreta in pregnancies of women with a history of cesarean section.

简介：AbstractObjective:To evaluate the efficacy and safety of a modified cesarean hysterectomy (MCH) procedure in controlling hemorrhage in patients with placenta previa complicated with placenta percreta.Methods:A retrospective analysis was conducted on 23 patients with placenta previa complicated with placenta percreta from January 2016 to December 2018 in the Union Hospital. The patients’ age ranged from 24 to 41 years, and had gestational durations of 32-38 weeks. Nine of them underwent MCH and 14 underwent conventional cesarean hysterectomy (CCH). In the MCH group, the bladder was not mobilized, deliberately. The uterus was excised horizontally above the tourniquet level. Placental tissue around the cervical os was cleaned thoroughly, and hemostatic suturing was performed under direct vision. In the CCH group, the uterus was removed gradually after programmed hemostasis and dissection of adhesions of the vesicouterine peritoneal fold and mobilization of the bladder.Results:There were no significant differences in general conditions between the two groups. The blood loss was significantly less in the MCH group (P < 0.05). The operation time was also decreased dramatically and hospital stay (in days) was shorter than in the CCH group (P < 0.05). There were no bladder or ureter injuries in the MCH group, compared with three cases in the CCH group. There were no statistically significant differences in neonatal birth weight, Apgar score, or intensive care unit admittance rates between the two groups (P > 0.05).Conclusion:This MCH procedure reduced blood loss, avoided bladder injury, and had no long-term complications. It is a safe, rapid, and effective way to control fatal hemorrhage during surgery for women with placenta previa complicated with placenta percreta.
