Vaginal Birth After Cesarean (VBAC)

If you’re expecting again after a previous cesarean section (C-section), you might be curious about vaginal birth after cesarean (VBAC). While VBAC is a viable option for many women, it’s crucial to prioritize your and your baby’s safety. Here’s a breakdown of key factors to consider with your doctor when deciding if VBAC is right for you.

Overall Health is Key

Both you and your baby’s health significantly impact VBAC feasibility. Even twins might be possible with VBAC if your doctor confirms everyone’s well-being. However, certain factors might make VBAC less suitable, such as:

• Obesity (BMI exceeding 30)
• Preeclampsia (high blood pressure during pregnancy)
• Age (generally above 35)
• Recent C-section (within 19 months)
• Large baby

C-section Scar Matter

The type of C-section scar on your uterus is a crucial detail to discuss with your doctor. There are two main incision directions:

• Vertical cut: Runs from top to bottom. VBAC is not recommended with this scar type due to a very high rupture risk during vaginal birth. In such cases, a repeat C-section is necessary.
• Low transverse cut: Runs from side to side. If you have this scar type and other risk factors are low, your doctor might approve VBAC.

Hospital Preparedness is Essential

Confirm early on if your chosen hospital supports VBAC. While the scar rupture risk during VBAC is low, the hospital must be equipped to handle this potential emergency. Not all hospitals meet this requirement.

Weighing the Risks of vaginal birth after cesarean (VBAC)

A small risk of uterine rupture exists for all VBAC attempts, even with a low transverse scar and good health. Doctors cannot guarantee it won’t happen. While ruptures are rare (less than 1% of VBACs), some women prefer to avoid VBAC altogether due to the potential severity of a rupture. Discussing your options with your doctor is vital before making a decision.

Benefits of Successful VBAC

If VBAC is a good fit for you and you’re interested in vaginal birth, there are compelling reasons to consider it:

• High success rate: Roughly 70% of VBAC attempts result in successful vaginal birth.
• No surgery required
• Reduced blood loss and faster recovery
• Lower infection risk
• Less chance of bladder or bowel injury
• Potentially fewer complications in future pregnancies

Making an Informed Choice

By carefully considering your health, scar type, hospital preparedness, potential risks, and the benefits of successful VBAC, you and your doctor can make an informed decision about whether VBAC is the right path for your next childbirth experience.
