ventriculoperitoneal shunt
Pronunciation: ven-trik-you-low-pair-ih-ton-EE-al
Surgical device that drains excess cerebrospinal fluid from brain ventricles to the abdominal cavity.
Full Definition
A ventriculoperitoneal (VP) shunt is a medical device consisting of a catheter system that diverts cerebrospinal fluid from the enlarged ventricles of the brain to the peritoneal cavity where it can be absorbed. This procedure is commonly performed in pediatric patients with hydrocephalus, whether congenital or acquired. The shunt includes a valve mechanism to regulate flow and prevent over-drainage. Complications include infection, obstruction, and over- or under-drainage. VP shunt documentation appears in neurosurgical reports, follow-up examinations, and emergency department evaluations for shunt malfunction. The device requires lifelong monitoring and may need revision.
Usage
Usage note: Often abbreviated as VP shunt in clinical notes. Distinguish from other shunt types like ventriculoatrial shunts.
