title: Morbidity associated with failed vaginal birth after cesarean section.
abstract: 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.
