Risks

While a successful VBAC is associated with fewer complications than an elective repeat C-section, a failed trial of labor after cesarean is associated with more complications, including, rarely, a uterine rupture. If a scar on your uterus from a previous cesarean tears open during a trial of labor, an emergency C-section is needed to prevent life-threatening complications for you and your baby. Treatment might involve surgical removal of the uterus (hysterectomy). If your uterus is removed, you won't be able to get pregnant again.
