Fetal surgery for spina bifida.

Area of Science:

• Neuroscience
• Developmental Biology
• Surgical Innovation

Background:

• Open neural tube defects, specifically myelomeningocele, present a two-hit model of neural injury.
• The Management of Myelomeningocele Study (MOMS) provided Level 1 evidence for prenatal surgical repair.
• Previous research has explored various factors including urological, orthopedic, radiological, and maternal outcomes.

Purpose of the Study:

• To evaluate the benefits of fetal repair for myelomeningocele.
• To explore advancements in surgical techniques for intrauterine intervention.
• To investigate long-term neurocognitive and motor function outcomes following fetal repair.

Main Methods:

• Review of existing literature and clinical studies on fetal myelomeningocele repair.
• Analysis of data from the Management of Myelomeningocele Study (MOMS).
• Exploration of emerging surgical technologies, including fetoscopic procedures.

Main Results:

• Prenatal repair of myelomeningocele led to reduced need for shunting and improved neurological function compared to postnatal repair.
• Further studies have elucidated associated urological, orthopedic, radiological, and maternal factors.
• Long-term neurocognitive and motor function data are still being collected and analyzed.

Conclusions:

• Fetal repair offers a viable strategy for improving outcomes in myelomeningocele.
• Minimally invasive techniques like fetoscopy are being developed to reduce maternal risks.
• Continued research is crucial for optimizing long-term functional results and shaping future treatment paradigms.
