ACOG practice bulletin. Vaginal birth after previous cesarean delivery. Number 2, October 1998. Clinical management guidelines for obstetrician-gynecologists. American College of Obstetricians and Gynecologists.

A trial of labor after previous cesarean delivery has been accepted as a way to lower the overall cesarean delivery rate. In 1995, 27.5% of women who had a previous cesarean delivery attempted vaginal birth; some clinicians believe that an even higher percentage is possible. Although there is a strong consensus that trial of labor is appropriate for most women who have had a previous low-transverse cesarean delivery, increased experience with vaginal birth after cesarean delivery (VBAC) indicates there are several potential problems. This document will review the current risks and benefits of VBAC in various situations and provide practical management guidelines.
