Spina bifida is a neural tube defect that occurs when the spinal column does not close completely during early fetal development. It can lead to a range of neurological impairments, including paralysis, bladder and bowel dysfunction, and hydrocephalus. Traditionally, treatment involved postnatal surgical repair; however, advances in fetal medicine have introduced the possibility of performing surgery while the baby is still in the womb, offering new hope for improved outcomes.
Fetal surgery for spina bifida typically involves repairing the opening in the spinal cord between 19 and 26 weeks of gestation. The procedure aims to protect the spinal cord from ongoing damage and reduce the severity of neurological deficits. Success rates for in-utero surgery have improved significantly over the past decade, primarily due to better surgical techniques, improved prenatal imaging, and comprehensive patient selection protocols.

One of the landmark studies in this field is the Management of Myelomeningocele Study (MOMS), a randomized controlled trial conducted in the United States. The MOMS trial compared prenatal surgery to standard postnatal repair and found that fetal surgery reduced the need for ventriculoperitoneal shunting (used to treat hydrocephalus) by approximately 50%, and improved motor outcomes at 30 months of age. Specifically, about 42% of children who underwent prenatal surgery achieved ambulation without assistive devices, compared to 21% in the postnatal group. These results underscore the potential of in-utero repair to significantly alter the disease trajectory. In-Utero Spina Bifida Surgery Success Rates In-Utero Spina Bifida Surgery Success Rates
However, the success of fetal spina bifida surgery is not without risks. Maternal complications such as uterine dehiscence, preterm labor, and placental issues can occur. For the fetus, risks include preterm birth, which remains a major concern since earlier delivery can limit neurological benefits. Despite these risks, the overall success rates remain encouraging, with many infants experiencing meaningful improvements in neurological function and quality of life.

While many children show improved motor and bladder function, some may still experience difficulties requiring ongoing medical management. Additionally, neurodevelopmental outcomes can vary widely depending on the severity of the defect and other associated anomalies. Nonetheless, the consensus in the medical community is that in-utero surgery offers a substantial advantage for selected cases, especially when performed in specialized centers with multidisciplinary teams.

As surgical techniques and prenatal diagnostics advance, it is anticipated that these success rates will continue to climb. Proper patient selection, counseling, and access to specialized fetal surgery centers are crucial to maximizing benefits and minimizing risks for both mother and child.
