Shunt insertion in newborns with myeloschisis/myelomenigocele and hydrocephalus

Abstract We compared two strategies for treating newborns with myeloschisis or myelomeningocele (open neural tube defect [oNTD]) and hydrocephalus. These strategies involved insertion of a ventriculo-peritoneal shunt (VPS) either synchronous with or sequential to surgical closure of the oNTD. We investigated shunt infection and cerebrospinal fluid (CSF) leakage rates and their effects on the duration of hospitalization for both treatments. The study involved 65 patients with hydrocephalus and open neural placodes which were covered with a thin pseudomembrane. Thirty-eight infants underwent an oNTD repair operation and shunting during the same surgical session (synchronous group [group 1]), and 27 infants underwent sequential procedures, in which shunt insertion was delayed until the thoracolumbar wound was partially healed (sequential group [group 2]). Group 1 had a mean duration of hospital stay of 15.5 days, significantly less than the average 28.8 days of group 2 ( p p > 0.05). The incidence of shunt infection due to CSF fistulas that developed postoperatively was higher for patients with CSF leakage as a result of oNTD at birth than for patients without CSF leakage ( p
