Pronounced: Ven-tric-cue-lo-perit-toe-neal shunt
A ventriculoperitoneal shunt is a tube that is placed under the skin. It runs from the brain to the belly. The tube allows extra fluid to drain from the brain into the belly. It is placed during a surgery.
This shunt is used to treat excess fluid in the brain. It is a condition called hydrocephalus. Excess fluid causes increased pressure in the head. This pressure can damage sensitive brain tissues. The shunt reduce pressure on the brain by draining the extra fluid.
