ventriculoperitoneal shunt
Pronunciation: ven-TRIK-yoo-loh-pair-ih-toh-NEE-al
Surgically placed drainage system redirecting cerebrospinal fluid from brain ventricles to the abdominal cavity.
Full Definition
A ventriculoperitoneal (VP) shunt is a medical device used to treat hydrocephalus by diverting excess cerebrospinal fluid from the brain's ventricular system to the peritoneal cavity where it can be absorbed. In neurosurgical oncology, VP shunts are frequently required when tumors obstruct normal CSF flow pathways or when treatment-related complications develop. The system consists of a ventricular catheter, valve mechanism, and peritoneal catheter connected by tubing. Editorial staff should note the correct hyphenation and abbreviation conventions, as shunt malfunction is a common complication requiring immediate medical attention.
Usage
Usage note: Hyphenate as shown. VP shunt is acceptable abbreviation after first use.
