If you’ve previously delivered by cesarean section, planning your next birth often comes with an important question: Should you attempt a vaginal birth after cesarean (VBAC) or schedule a repeat C-section?
The answer is highly personal and depends on several factors, including your medical history, the reason for your previous C-section, your current pregnancy, and your future family planning goals. Both options can be safe and appropriate, which is why the decision is best made in partnership with your OB/GYN.
Here’s what to know about the benefits, risks, and considerations that help guide this important birth-planning decision.
What Is a VBAC?
VBAC stands for Vaginal Birth After Cesarean. To achieve a VBAC, a patient undergoes a Trial of Labor After Cesarean (TOLAC), meaning labor is attempted with the goal of delivering vaginally. If labor progresses successfully, the result is a VBAC. If complications arise or labor does not progress appropriately, a cesarean delivery may still be needed.
Years ago, a repeat cesarean was routinely recommended after a prior C-section. Today, research shows that many women with a previous cesarean may be candidates for a safe VBAC, depending on their individual circumstances.
Benefits of Choosing a VBAC
For eligible patients, a successful VBAC offers several potential advantages.
According to the American College of Obstetricians and Gynecologists (ACOG), successful VBACs are associated with:
- No additional abdominal surgery
- Shorter recovery times
- Lower risk of infection
- Less blood loss
- Shorter hospital stays
- Faster return to normal activities
VBAC may also reduce complications associated with multiple cesarean deliveries. Each additional C-section can increase the risk of scar tissue formation, surgical injury, and certain placental complications in future pregnancies.
For women planning to have more children, avoiding multiple surgeries may be an important consideration.
Benefits of a Repeat C-Section
A repeat cesarean delivery also offers advantages and may be the safest choice for some pregnancies.
Potential benefits include:
- A planned delivery date
- Avoiding the uncertainty of labor
- Eliminating the possibility of a failed TOLAC
- Avoiding the risk of uterine rupture associated with VBAC attempts
For some women, particularly those with certain uterine incision types or pregnancy complications, a repeat cesarean may provide the lowest-risk delivery option.
Additionally, some patients simply feel more comfortable choosing a delivery experience they have already been through, and personal preference is an important part of the conversation.
Understanding the Risks of VBAC
The most significant concern associated with a VBAC is uterine rupture, a rare but serious complication in which the scar from a previous cesarean separates during labor. This can pose risks to both mother and baby and may require emergency surgery.
Fortunately, uterine rupture remains uncommon. Research generally places the risk at less than 1% for women with one prior low-transverse cesarean incision.
It’s important to remember that while this risk receives significant attention, many VBAC attempts are successful. Studies consistently show success rates ranging from approximately 60% to 80% among appropriately selected candidates.
Factors That Influence VBAC Success
Not everyone is an ideal candidate for a VBAC. Your OB/GYN will evaluate several factors before making a recommendation.
Factors that may improve the likelihood of a successful VBAC include:
- A previous vaginal delivery
- A previous successful VBAC
- A prior cesarean performed for a non-recurring reason, such as breech presentation
- A healthy, uncomplicated current pregnancy
Factors that may make a repeat C-section the safer option include:
- Certain types of uterine incisions
- Multiple prior cesarean deliveries in some circumstances
- Placenta previa or other placental complications
- Certain maternal or fetal health concerns
- Conditions that would make vaginal delivery unsafe regardless of prior cesarean history
Every pregnancy is different, which is why individualized counseling is essential.
Questions to Discuss With Your OB/GYN
As you build your birth plan, consider discussing the following with your provider:
- Am I a good candidate for VBAC?
- What was the reason for my previous C-section?
- What type of uterine incision was used?
- What are the risks and benefits specific to my pregnancy?
- Does the hospital where I plan to deliver support VBAC?
- How might my future family planning goals affect this decision?
These conversations often begin early in pregnancy and may evolve as your pregnancy progresses.
There Is No One “Right” Choice
One of the most important things to remember is that there is no universally correct answer when choosing between a VBAC and a repeat C-section.
For some women, a VBAC offers the opportunity for a shorter recovery and avoidance of another surgery. For others, a planned repeat cesarean provides reassurance and the safest path forward. Both choices can result in healthy outcomes for mother and baby.
At CT Coastal OB/GYN, we believe every birth plan should be guided by evidence-based medicine, open communication, and your personal goals. Our team works closely with patients to evaluate risks, answer questions, and help determine the delivery approach that best supports a safe and positive birth experience.
The goal isn’t simply choosing VBAC or repeat C-section; it’s choosing the option that’s right for you and your baby.
