Vaginal birth after cesarean delivery: evidence-based practice.

Given the high national rate of cesarean delivery in current obstetric practice, patients considering vaginal birth after cesarean (VBAC) in subsequent pregnancies are frequently encountered. A recently growing body of literature on VBAC has produced concrete evidence to define the VBAC-associated risks and identify factors influencing success. An evidence-based approach can guide practitioners and patients through the complex counseling, decision-making, and management issues when considering VBAC delivery.
