Key Points About VBAC
What is VBAC?
- VBAC stands for vaginal birth after cesarean. It involves attempting a vaginal delivery after having had a previous C-section.

Who is a Candidate for VBAC?
- Most people with one previous low-transverse (side-to-side) uterine incision are considered candidates.
- You are less likely to be a candidate if you have had a classical (vertical) uterine incision, more than one prior C-section, or a history of uterine rupture or other uterine surgery.
- Other factors that can affect candidacy include the reason for your previous C-section, your overall health, the presence of certain pregnancy complications, and the resources available at your hospital.Vaginal Birth After Cesarean Delivery - StatPearls - NCBI BookshelfVaginal birth after cesarean section (VBAC) is the term applied to patients who undergo vaginal delivery following cesarean delivery in a prior pregnancy.

Factors That Affect VBAC Success
- Higher chance of success if your previous C-section was for a non-recurrent reason (like breech baby or fetal distress, not labor that didn’t progress).
- Prior vaginal delivery (before or after your C-section) increases the likelihood of a successful VBAC.
- Spontaneous (natural) onset of labor is associated with higher success rates than induced labor.
- Factors that may decrease success rates include maternal age over 35, obesity, diabetes, pregnancy past 40 weeks, and a large baby (over 4 kg).Vaginal Birth After Cesarean Delivery - StatPearls - NCBI BookshelfVaginal birth after cesarean section (VBAC) is the term applied to patients who undergo vaginal delivery following cesarean delivery in a prior pregnancy.

Risks of VBAC
- The main risk is uterine rupture, where the scar from the previous C-section tears during labor. This is rare (less than 1% of cases), but it is a serious complication that can be dangerous for both you and your baby.
- Other risks include infection, bleeding, and the possibility of needing an emergency C-section if labor does not progress or if complications arise.Vaginal Birth After Cesarean Delivery - StatPearls - NCBI BookshelfVaginal birth after cesarean section (VBAC) is the term applied to patients who undergo vaginal delivery following cesarean delivery in a prior pregnancy.

Overview
A good candidate for a VBAC (vaginal birth after cesarean) is someone whose medical and pregnancy history suggests a high likelihood of a safe and successful vaginal delivery after a previous C-section. Several factors can increase or decrease your chances of success.
Key Factors That Make Someone a Good Candidate for VBAC
Type of Uterine Incision
- Low-transverse (horizontal) incision: This is the most common and safest type for VBAC, with the lowest risk of uterine rupture.
- Other incisions (classical/vertical or T-shaped): These are usually considered higher risk and are generally not recommended for VBAC.ACOG Releases Guidelines for Vaginal Birth After Cesarean Delivery | AAFPCriteria for selecting candidates for VBAC include the following: (1) one previous low-transverse cesarean delivery; (2) clinically adequate pelvis; (3) no other uterine scars or previous rupture; (4) a physician immediately available throughout active labor who is capable of monitoring labor ...Deciding Between a VBAC and a Repeat Cesarean: 7 Questions to Ask | ACOGSome health conditions are known to lower your chances of a successful VBAC, including obesity and preeclampsia.

Reason for Previous C-Section
- Non-recurrent reasons: If your previous C-section was for reasons unlikely to happen again (such as breech baby or fetal distress), your chances of a successful VBAC are higher.
- Recurrent reasons: If your C-section was for reasons like labor not progressing (cephalopelvic disproportion), your chance of VBAC success may be lower, but it is not an absolute barrier.Vaginal Birth After Cesarean Delivery - StatPearls - NCBI BookshelfEffective counseling is essential for VBAC candidates, focusing on risks, benefits, and factors influencing success, eg, prior vaginal deliveries, spontaneous labor, and nonrecurrent indications for cesarean.
