A ventriculoperitoneal shunt is a medical device used to treat conditions like hydrocephalus, where excess cerebrospinal fluid (CSF) accumulates in the brain's ventricles. The shunt consists of a flexible tube that drains the excess fluid from the brain to the peritoneal cavity in the abdomen, where it can be absorbed by the body. The procedure to place a ventriculoperitoneal shunt is typically performed by a neurosurgeon. After the shunt is implanted, it helps to regulate CSF levels, relieving pressure on the brain and preventing complications associated with fluid buildup. Regular follow-ups are necessary to ensure the shunt is functioning properly.
