Abstract
Slipping of the lumboperitoneal (LP) shunt system into the peritoneal cavity is a rare but serious complication of this procedure. The authors treated a 12-year-old boy with idiopathic intracranial hypertension who presented with headache and vomiting, and who had undergone LP shunt using the conventional shunt system with ordinary fixture tab. Three days after the operation, the whole system slipped into the abdominal cavity. The second operation of LP shunt was performed using a new silicon fixture device with three small holes. The patient left the hospital 2 weeks after the 2nd operation absent of any neurological symptoms. This new device enables better fixation of the LP shunt system to the lumbodorsal fascia, as compared to the conventional LP shunt system.
