The Shunt Slippage: A Complication of Pumping Test

Surgery for the placement of a ventriculoperitoneal shunt incurs numerous procedure-related complications. Distal dislodgment of the device from the cranial insertion site after pumping of the shunt chamber has rarely occurred and it has not been evaluated to date. Herein, we report an interesting case of a 20-year-old man who underwent shunt revision for ventricular catheter migration after a manual pumping test. We reviewed previously reported cases related to such rare conditions and described a simple method of valve fixation for preventing disconnection and migration of the proximal shunt system.
