What is a VP shunt and how does it work to treat hydrocephalus?
A ventriculoperitoneal (VP) shunt is a surgically implanted drainage system that diverts excess cerebrospinal fluid (CSF) from the brain’s ventricles to the abdominal cavity, where it is absorbed by the body. It consists of a ventricular catheter, a pressure-regulating valve, and a peritoneal catheter.
What are the signs of VP shunt malfunction or failure and what should I do?
Signs of shunt failure include return of headaches, nausea, vomiting, vision changes, cognitive decline, and drowsinesssimilar to pre-surgery hydrocephalus symptoms. Shunt failure is a medical emergency. If you experience these symptoms after VP shunt surgery, go to the emergency department immediately for evaluation.
How long does a VP shunt last and will it ever need to be replaced?
VP shunts can function for many years, but they may require revision or replacement due to blockage, infection, or mechanical failure. Children often need shunt revisions as they grow. Adults with properly functioning shunts may not require revision for many years. Regular neurosurgical follow-up is essential to monitor shunt function.
