We investigated morbidity and factors associated with failed vaginal birth after cesarean delivery (VBAC). In a retrospective cohort study maternal and neonatal outcomes of women who underwent VBAC in three Nigerian University Teaching Hospitals were reviewed. Univariate, followed by multivariate analyses, were conducted. VBAC was successful in 683 of 1,013 women (67.4%), whereas 330 (32.6%) had failed VBAC. Failed VBAC was associated with higher incidence of chorioamnionitis, postpartum hemorrhage, blood transfusion, uterine rupture, hysterectomy, and composite major neonatal morbidities. Younger age, lack of previous vaginal delivery, induction of labor and fetal weight >4,000 g were risk factors for failed VBAC. A majority of women who try VBAC achieve a vaginal delivery. Failed VBAC is associated with increased maternal and neonatal morbidity and is somewhat predictable.
我们研究了剖宫产后阴道分娩失败（VBAC）的发病率和相关因素。在一项回顾性队列研究中，我们回顾了在尼日利亚三所大学教学医院接受 VBAC 的女性的母婴结局。进行了单变量和多变量分析。在 1013 名妇女中，683 名（67.4%）VBAC 成功，330 名（32.6%）VBAC 失败。VBAC 失败与绒毛膜羊膜炎、产后出血、输血、子宫破裂、子宫切除术和复合主要新生儿并发症的发生率较高相关。年龄较小、无既往阴道分娩史、引产和胎儿体重>4000g 是 VBAC 失败的危险因素。大多数尝试 VBAC 的女性都能实现阴道分娩。VBAC 失败与母婴发病率增加有关，且具有一定的可预测性。
