Know Your Options: Vaginal Birth After Cesarean (VBAC)

If you have had a cesarean section (C-section), you are not alone. In fact, according to the Centers for Disease Control and Prevention (CDC), in 2017, 35% of births in Texas were C-sections. But just because you have had a C-section in the past, doesn’t mean it is your only option in the future. Today many women can undergo a VBAC, which stands for “vaginal birth after cesarean” and refers to giving birth through the vagina after a woman has already had a cesarean section.

However, there are many factors to weigh when considering a VBAC, and women who wish to attempt a VBAC must talk with their Women’s Health Texas ObGyn to see if they are a candidate. Here are some important facts to know if you are considering a VBAC.

Risks associated with VBACs:

  • While this occurs less than 1% of the time, one risk with VBAC is that C-sections leaves a scar on the uterus, and the pressure from vaginal labor could cause the scar on the uterus to rupture. Hospitals must be equipped with a surgical and anesthesia team should an emergency C-section be needed.
  • VBAC is not advised for women who have had any prior uterine ruptures or other abdominal scars.

Factors increasing the chance of a successful VBAC:

  • Previous vaginal delivery
  • Being younger than 35
  • Natural versus induced labor
  • Reason for previous C-section not likely to recur, such as breach (feet-down) presentation or fetal distress
  • Prior C-section not done for stalled labor
  • Low-transverse (side-to-side) incisions, which carry the least chance of rupture

Factors decreasing the chance of a successful VBAC:

  • Being overweight
  • Being older than 35
  • Pregnancy beyond 40 weeks
  • High birth weight of the baby (more than 9 lbs.)
  • Pregnancy-induced hypertension
  • Short time span between pregnancies (fewer than 18 months)
  • Multiple prior C-sections
  • Prior C-section caused by difficult labor (dystocia)
  • Chronic conditions, such as diabetes, heart disease, or high blood pressure, that can affect vaginal birth
  • A small pelvis that may not be able to handle vaginal birth
  • High-vertical (up-and-down) incisions, which carry the most chance of rupture

Benefits of vaginal versus surgical birth:

  • Faster recovery time
  • Shorter hospital stay
  • Prevention of potential surgery complications
  • Reduced risk of complications associated with multiple C-sections, including hysterectomy and problems with the placenta
  • Reduced chance for a blood transfusion
  • Easier time with breastfeeding without an abdominal incision
