VBAC
Pronunciation: VEE-bak
Also written as: VBAC — Vaginal Birth After Cesarean
Vaginal birth after cesarean section, referring to vaginal delivery in women with previous cesarean births.
Full Definition
VBAC (Vaginal Birth After Cesarean) refers to the process of delivering a baby vaginally after having had one or more previous cesarean deliveries. This approach is considered for appropriate candidates as an alternative to repeat cesarean section. VBAC success rates vary depending on factors such as the reason for previous cesarean, type of uterine incision, and maternal characteristics. The main concern is uterine rupture, which occurs in less than 1% of VBAC attempts but can be life-threatening. Careful patient selection and continuous monitoring during labor are essential.
Usage
Usage note: Often used interchangeably with TOLAC (trial of labor after cesarean), though technically VBAC refers to successful vaginal delivery.
