The open surgical repair of myelomeningoceles before 26 weeks gestational age provides a correction of the anomaly of Chiarri, reduces the incidence of ventriculomegaly (defined as a measure of the ventricles at the crossroads ≥ 10 mm), and get a lower of injury than one corresponding to the anatomical defect (as defined by the last upper normal vertebra before the defect).

The purpose of this study is to introduce in France an innovative technique for prenatal repair of myelomeningocele until now developed only on the American continent.

Arms Assigned Interventions
No Intervention: no surgery
Experimental: open surgical repair
open surgical repair of myelomeningocele before 26 SA
Procedure: prenatal surgical repair of fetal myelomeningocele
open surgical repair of myelomeningocele before 26 weeks gestational age

Detailed Description:

Spina bifida (SB) represents one of the most severe congenital malformation of the central nervous system and amenable to prenatal diagnosis. In the past 20 years, prenatal repair of SB has become an established technique.

The PRIUM study will include 10 cases of fetuses with prenatal diagnosis of SB and for whom the maternal willing will be to continue the pregnancy. A surgical prenatal repair of the defect will be planed at 19-25+6 weeks gestation following maternal laparotomy and hysterotomy under maternal general anesthesia. The delivery will be planed at 36 weeks'. Postnatal evaluation of the neonates will be scheduled at birth, 1 month and 12 months od age. Those data will be matched to controls who have underwent a conventional postnatal repair of the SB
