Cranial migration of complete ventriculo-peritoneal shunt assembly

Abstract A 10-month-old male child with severe congenital hydrocephalus due to aqueduct stenosis presented with cranial migration of the entire ventriculo-peritoneal (VP) shunt. The complete shunt assembly, including the shunt chamber, was noted in the dilated ventricles. The migrated shunt was left in situ . A VP shunt was performed on the opposite side. The complete intraventricular migration of a VP shunt is a rare complication. This complication may be avoided by firm anchoring of the connector sites to the periosteum, and avoidance of large burr holes and dural openings. The possible mechanisms of such an event and the relevant literature are discussed.
