Do I Need a C-Section for a Baby With Spina Bifida?

Whether you need a Cesarean section (C-section) for a baby with open spinal dysraphism (such as myelomeningocele or spina bifida) depends heavily on when your baby undergoes surgery. If you had open fetal surgery during pregnancy, a C-section is strictly required. If the baby’s surgery is planned for after birth (postnatal repair), a C-section is highly recommended by most specialists to protect the baby, though the medical evidence is nuanced.

Delivery After Fetal Surgery

If you chose to have prenatal repair for your baby’s spina bifida, your delivery plan is largely dictated by the type of fetal surgery performed.

Open Fetal Surgery: For mothers who have undergone open fetal surgery (which involves opening the uterus to operate on the baby), an elective C-section is strictly required ^[1][2]. The incision made in the uterus during open fetal surgery creates a hysterotomy scar. Attempting labor and vaginal birth places significant physical stress on this scar, carrying a serious risk of uterine rupture ^[1][3]. Uterine rupture is a severe complication that can be life-threatening for both the mother and baby ^[2][4]. Because of this risk, labor is avoided entirely, and a C-section is usually scheduled around 37 weeks of pregnancy ^[5].

Fetoscopic Surgery: If you had minimally invasive (fetoscopic) surgery, the risk of uterine rupture is generally lower than with open surgery ^[6][7]. While vaginal delivery might be possible in carefully selected situations, the safest approach depends on your specific medical details ^[8]. Any prenatal surgery—open or fetoscopic—significantly increases the risk of preterm delivery, which may also impact the timing and method of birth ^[9][10].

Delivery Before Postnatal Surgery

If your baby will have surgery to close the spinal opening after birth, the recommendations for delivery are different.

Historically, most specialists have highly recommended elective C-sections for babies with open spina bifida whose backs have not yet been repaired. The primary reason is the concern that the physical forces of labor and a vaginal delivery might cause a large, fluid-filled sac on the baby’s back to rupture. This can cause a rapid loss of cerebrospinal fluid and severely increase the risk of infection ^[11][12]. There is also theoretical concern of mechanical trauma to the baby’s exposed spinal cord (neural placode) ^[11]. For these reasons, your medical team will likely prefer to plan a C-section to protect the baby during birth.

However, recent medical studies evaluating these concerns have found no definitive evidence that a C-section actually improves a baby’s neurological outcomes, motor function, or long-term ability to walk compared to a vaginal delivery ^[13][14]. Studies tracking infants with prenatally diagnosed myelomeningocele have concluded there is no demonstrated statistical benefit to motor or neurological outcomes from avoiding labor ^[15][16].

Despite the lack of strong data proving that a C-section prevents nerve damage during birth, scheduling a C-section remains widely adopted in clinical practice ^[11][16]. Your care team will weigh the theoretical benefits of protecting the baby’s spine against the standard surgical risks of a C-section for the mother.

Building Your Birth Plan

When planning your delivery, your team of specialists—including your obstetrician, maternal-fetal medicine specialist, neonatologist, and pediatric neurosurgeon—will collaborate to find the safest option. Factors that influence your birth plan include:

• Prior fetal surgery: Whether you had open vs. fetoscopic repair.
• Fetal head size: Babies with spina bifida often have hydrocephalus (excess fluid in the brain), which can cause an enlarged head (macrocrania) that makes vaginal delivery physically difficult or unsafe.
• Lesion specifics: A very large or thin-walled, fluid-filled sac on the baby’s back strongly increases the risk of rupture, making vaginal delivery too risky.
• Preterm labor: Pregnancies with neural tube defects have higher rates of early labor ^[17][18].

What to Expect if Labor Starts Early

Because premature labor is common ^[17][18], your medical team will help you establish an emergency plan. If your water breaks or contractions start before your scheduled date, you should head immediately to the specialized hospital equipped to handle your delivery. In most cases—especially if you had open fetal surgery or the baby’s lesion is unprotected—an emergency C-section will be performed upon arrival ^[1]. Recovering from major abdominal surgery like a C-section while your newborn is in the NICU for spinal surgery is physically and emotionally taxing. Arranging a strong postpartum support system to help you recover and navigate this time is highly recommended.
