Prenatal neurosurgical counseling for conditions affecting the fetal nervous system

Introduction: Spina bifida guidelines recommend neurosurgical involvement in prenatal counseling (nPNC) to inform decision-making between prenatal and postnatal MMC repair. This study examines whether families with myelomeningocele (MMC) presenting to one fetal center had timely nPNC encounters, and assesses modifiable and non-modifiable treatment-determining factors. Methods: History and timing of nPNC were quantified among infants undergoing postnatal and prenatal MMC repair, pregnant patients referred, and MMC studies in a fetal MRI database (2015-2023). Fetal repair exclusions, presentation timing, social determinants, and reported rationale for not selecting offered fetal therapy were assessed. Results: Nearly all patients (34/35; 97%) engaged in nPNC, 82% prior to 24 weeks GA. Fourteen patients were excluded from fetal repair for lack of hindbrain herniation (43%), obstetric exclusions (21%), fetal exclusions (21%), suspected closed defect (7%), and delayed presentation (7%). These patients ultimately underwent postnatal repair (71%), and pregnancy termination (14%). The 20 fetal-repair-eligible patients selected fetal repair (50%), postnatal repair (45%), and pregnancy termination (5%). Reasons for declining fetal repair included risk (55%) and cost (22%). Conclusions: Among MMC families presenting to a regional fetal therapy center, nPNC was widely extended, in a mostly timely fashion. Very few were deterred from fetal repair by potentially modifiable barriers.
