Experience in the management of myelomeningocele in Puerto Rico.

The medical records of 128 children with myelomeningocele who were treated at the Pediatric University Hospital, Puerto Rico Medical Center, from January, 1980, to July, 1985, were reviewed retrospectively. The medical and surgical management during the first hospitalization of these children was studied in detail for predefined parameters. The average age at the time of myelomeningocele repair was 6.6 days. Statistical analysis showed that repair of the myelomeningocele defect before 48 hours of age did not reduce the occurrence of ventriculitis. The incidence of ventriculitis secondary to the management of the myelomeningocele lesion was 12.5%. Complications after repair of the myelomeningocele (including skin flap necrosis, cerebrospinal fluid leaks, and wound infection) were present in 43.8% of the patients who developed ventriculitis and in 19.0% of those who did not. This observation is statistically significant (p = 0.03) and indicates that complications of healing after myelomeningocele repair represent the most significant risk factor for the development of ventriculitis.
