[Prenatal repair of myelomeningocele: State of the art]

Abstract

Myelomeningocele is characterized by the extrusion of the spinal cord into a sac filled with cerebrospinal fluid. One part of the postnatal disabilities could be related to the spinal damage and to the cerebral repercussion of the leak of cerebrospinal fluid from the defect. Several experimental studies in animals have demonstrated that a surgical repair of the lesion at middle gestation reduced the postnatal disabilities. These results were confirmed in humans by the Management of Myelomeningocele (MOM) Trial. However, the prenatal surgical repair is associated with maternal and fetal morbidity.
