The overall VBAC success rate is approximately 60 to 80 percent. Factors such as previous vaginal delivery, reason for prior cesarean, and maternal health significantly influence the outcome.
Who is not a candidate for VBAC?
VBAC is generally not recommended for individuals with a classical (vertical) uterine incision, prior uterine rupture, or certain placental abnormalities. A healthcare provider should evaluate each case.
