Minimal exposure maximal precision ventriculoperitoneal shunt: how I do it.

Abstract

Ventriculoperitoneal shunt is among the most frequent neurosurgical procedures, complicated by infection and obstruction. The first is influenced by number of skin incisions, catheter exposure and manipulation, and the latter by catheter position. Presenting our neuronavigated laparoscopic-assisted minimal exposure shunt technique performed on 40 consecutive adults. No patient presented infection or distal catheter migration (mean follow-up 12 months). Ventricular catheter malpositioning associated with electromagnetic neuronavigation inaccuracy occurred in two patients with slit ventricles. This technique demonstrates low infection/malfunction rate, postoperative pain, and cosmetic advantages. Limiting factors are availability of laparoscopic surgeons and neuronavigation if not familiar with the approach.
