Which outcome may be improved by fetal surgery for spina bifida?

• A. Improvement in lower-extremity function and greater likelihood to walk without devices
• B. No improvement in any neurological outcome
• C. Worsened brain development
• D. Cure for hydrocephalus completely

Answer: (A)

Fetal repair for spina bifida aims to protect the exposed spinal cord during development, which can preserve motor pathways in the lower spine. Evidence from studies comparing prenatal repair to standard postnatal repair shows that babies who undergo prenatal repair often have better lower-extremity motor function and are more likely to walk independently without braces or devices by early childhood. This is the main neurological benefit associated with fetal surgery. It does not provide a guaranteed cure for hydrocephalus, since some children still need shunts, and it does not worsen brain development on average. There are also risks to pregnancy, including prematurity and maternal-fetal complications, but the key point is the potential improvement in leg function and walking ability.
