VBAC
Pronunciation: VEE-back
Also written as: VBAC — Vaginal Birth After Cesarean
Vaginal birth after cesarean section, referring to vaginal delivery following a previous cesarean delivery.
Full Definition
VBAC (Vaginal Birth After Cesarean) describes the option for women who have had a previous cesarean section to attempt vaginal delivery in subsequent pregnancies. Success rates vary depending on factors such as the type of previous uterine incision, reason for prior cesarean, and current pregnancy conditions. VBAC candidates require careful screening and monitoring due to the small but significant risk of uterine rupture. Benefits of successful VBAC include shorter recovery time, reduced infection risk, and avoidance of repeat surgical complications. However, immediate surgical capability must be available in case emergency cesarean becomes necessary during the trial of labor.
Usage
Usage note: Often used interchangeably with TOLAC (Trial of Labor After Cesarean), though TOLAC refers to the attempt and VBAC to the successful outcome.
