DIAGNOSIS AND MANAGEMENT OF PRENATALLY DETECTED MYELOMENINGOCELE - A PRELIMINARY-REPORT

Our experience with 23 cases of fetal myelomeningocele provides preliminary information on the outcome of these infants diagnosed in utero and managed by a multidisciplinary team. The mean age of diagnosis was 23.7 weeks (range, 16 to 34 weeks). Mean gestational age at delivery was 36.9 weeks in the 14 patients who elected to continue their pregnancies. None of the 11 infants with lumbosacral or sacral lesions developed significant ventriculomegaly before term. Of the three patients diagnosed with thoracolumbar lesions, two had progression of ventriculomegaly necessitating early delivery at 32 to 34 weeks of gestation. These preliminary findings suggest that a coordinated prenatal and neonatal approach appears to result in a favorable prognosis for infants with myelomeningocele, but that neonatal complications are common, requiring careful monitoring and aggressive management. © 1990.
