>J Pediatr (Rio J) 1995;71(6):317-321: spinal dysraphism, myelomeningocele, spina bifida, hydrocephalus, Chiari II malformation. The authors made a retrospective study of 72 patients with myelomeningocele treated at a pediatric hospital in Rio de Janeiro, Brazil. 65 (90.2%) lesions involved the inferior segments of the spine and 87.5% of the patients needed shunt procedures for hydrocephalus control. Shunt infections in spina bifida cystica patients were more frequent than in any other group of hydrocephalic patients treated at the institution. There was a great incidence of postoperative complications such as wound infections and skin necrosis. 11 (15.3%) patients developed signs and symptoms related to Chiari II malformation. The overall mortality was 8.3%, and in most of the cases, ascribed to the Chiari malformation.
