What is the purpose of a ventriculoperitoneal (VP) shunt?

• A. Relieves hydrocephalus by diverting CSF to the peritoneal cavity
• B. Increases CSF production
• C. Treats intracranial hemorrhage
• D. Drains CSF to the chest cavity

Answer: (A)

A ventriculoperitoneal shunt is used to relieve hydrocephalus by diverting excess cerebrospinal fluid from the brain’s ventricles into the peritoneal cavity, where it can be absorbed. It works with a small catheter and a valve to regulate flow and prevent overdrainage, thereby lowering intracranial pressure. It does not increase CSF production, it is not intended to treat intracranial hemorrhage, and draining to the chest cavity would involve a different type of shunt (ventriculopleural).
