title: Shunt complications in children with myelomeningocele: effect of timing of shunt placement. Clinical article.
abstract: OBJECT There has been controversy over whether CSF shunt insertion simultaneously with repair of myelomeningocele (MMC) might increase shunt-related complications. The purpose of this study was to evaluate shunt complication rates in patients who underwent concurrent MMC surgery and shunt placement and compare them to the rates in patients treated with shunt placement in a separate procedure. METHODS The authors retrospectively reviewed the outcome of shunt placement in 127 patients with MMC who were followed up for >or=1 year after shunt surgery. In 65 patients shunt surgery was performed in a second operation after MMC repair and in 46 the 2 procedures were performed concurrently. In 7 patients shunt placement was the initial surgery, and in 9 it was the only procedure performed. The patients were evaluated for shunt complications. RESULTS There was no statistically significant between-groups difference in age at which patients underwent shunt placement. The overall rates of shunt infection and shunt malfunction were 16.5 and 39.4%, respectively. There was a high rate of shunt infection and mortality in those patients treated with CSF shunting only. There was no statistically significant difference between complication rates in patients in whom the 2 procedures were performed concurrently and those who underwent separate operations. CONCLUSIONS The order in which myelomeningocele repair and shunt placement were carried out did not have a significant effect on the rate of shunt complications. Thus, when indicated these procedures can be performed concurrently with a level of risk comparable to that associated with delayed shunt placement.
