Fetal spina bifida

Last edited: 4/16/2026

Overview

Spina bifida is a neural tube defect characterized by incomplete closure of the spinal column, leading to potential neurological deficits and varying degrees of disability depending on the severity 1.

Diagnosis

  • Prenatal diagnosis often achieved via maternal serum alpha-fetoprotein (MSAFP) screening and detailed ultrasound 1.
  • Magnetic resonance imaging (MRI) can provide detailed anatomical assessment postnatally 1.
  • Fetal MRI may be used to further evaluate severity and associated anomalies 1.
  • Management

  • First-line: Surgical closure of the myelomeningocele in utero may be considered to reduce postnatal complications 1.
  • Postnatal: Early surgical intervention for hydrocephalus management, often involving ventriculoperitoneal (VP) shunt placement 1.
  • Supportive care: Physical therapy, orthopedic interventions, and multidisciplinary care teams including neurology, urology, and rehabilitation specialists 1.
  • Special Populations

  • Pregnancy: Maternal-fetal medicine (MFM) specialists more frequently offer growth ultrasounds and neonatal hospice consultations compared to non-MFM providers 1.
  • Pediatrics: Neonatal management focuses on preventing complications such as infection, optimizing neurological outcomes, and addressing orthopedic issues 1.
  • Key Recommendations

  • Maternal-fetal medicine specialists should be involved in pregnancies complicated by fetal spina bifida to optimize prenatal care and counseling 1 (Evidence: Moderate).
  • Offer detailed fetal imaging (ultrasound, MRI) to assess the extent of the defect and associated anomalies 1 (Evidence: Strong).
  • Consider antenatal surgical intervention for myelomeningocele closure to potentially improve outcomes 1 (Evidence: Moderate).
  • Postnatal management should include prompt surgical intervention for hydrocephalus and comprehensive multidisciplinary support 1 (Evidence: Strong).
