Shunt migration

Abdominal catheter migration

Ventricular catheter migration

In 137 patients undergoing 157 new VP shunt procedures with an average age of 57.7±standard deviation of 18.4years old. There were 16 distal shunt migrations. Body mass index >30kg/m(2) and number of previous shunt procedures were found to be independent risk factors for distal catheter migration. Obesity and number of previous shunt procedures were factors for distal catheter migration. Providers and patients should be aware of these possible risk factors prior to VP shunt placement 1).


Skadorwa and Ciszek, present two cases of traumatic intracranial migration of the ventriculoperitoneal (VPS) valve chamber without malfunction of the system. In both patients, a shunt reservoir was surgically repositioned without a burr hole expansion and with no implantation of a new VPS system. They discuss a role of a head trauma and repeated valve palpation in this rare complication 2).
