VBAC: Am I a Candidate?

March 22, 2018

Women planning to have a vaginal delivery are often devastated when fate takes an unexpected turn and their baby is delivered via C-section. To complicate matters, mothers may find their healthcare provider is reluctant to perform a vaginal delivery after a C-section (VBAC) because s/he worries about potential complications.

The good news is that evidence supports VBACs in the right situations, giving women a second- (or third) chance at the labor and delivery they wanted the first-time around. In fact, the American Pregnancy Association states that 90% of women who’ve had a caesarian sections are candidates for VBACs (hooray!).

While your choices and emotional well-being are a top priority, it’s worth noting there are plenty of other good reasons to strive for a VBAC if you can. By doing so you, avoid a major surgical procedure, reduce your risk of postpartum infection and enjoy a shorter hospital stay and postpartum recovery.

What Makes a Good Candidate for a VBAC?

Here are the things an OB wants to see to support a VBAC birth plan:

You’ve had a successful vaginal delivery in the past

Whether you’ve had your vaginal delivery prior to the C-section, or as a VBAC, a successful vaginal birth is a positive note in the medical records when it comes to determining VBAC status.

You are 35-years or younger

This is not to say that women over the age of 35-years old can’t have a VBAC. However, studies have shown that women under the age of 35 tend to have more successful VBACs, with fewer complications.

Your C-section was performed using a low-transverse incision.

The greatest risk of a VBAC is a ruptured uterus, which occurs if the prior C-section incision left the uterine lining weak, causing it to rupture or tear during a vaginal labor/delivery. Low-transverse incisions (an incision made side-to-side on the lower portion of the abdomen) pose the least likely threat of rupture in the future.

On the flip-side, if a high, vertical incision (top to bottom) was used, your doctor may not be willing to move forward with a VBAC since these are more prone to rupture.

You’ve had two or less C-sections

The more C-sections (incisions) you’ve had, the higher the risk of uterine rupture. Thus, the best VBAC candidates have only had one C-section (optimal), or two at the most.

The C-section was performed to protect baby’s health, not yours

The reason for your prior C-section matters to the physician. If you had a C-section because something was happening to baby (low heart rate, signs of distress, etc.) that’s one thing. If it occurred because the your physical labor wasn’t progressing as it should (cervix not dilating, a small pelvis, genital herpes, etc.), the doctor may advise a C-section for future deliveries.

You ‘re free of other uterine anomalies

If your uterus has other anomalies, uterine scarring or a history of uterine ruptures, C-Section is a healthier delivery option.

You have a healthy, non-risk pregnancy

If your pregnancy is considered high-risk for any reason – gestational diabetes, a breech baby, multiples, history of placenta previa, etc., the doctor will recommend a C-section.
