What is the tube called that is implanted in the brain to relieve the pressure of cerebrospinal fluid as a result of hydrocephalus?

The tube implanted in the brain to relieve pressure from cerebrospinal fluid due to hydrocephalus is called a shunt, specifically a ventriculoperitoneal (VP) shunt. This device helps to drain excess cerebrospinal fluid from the ventricles of the brain to another area of the body, typically the abdominal cavity, where it can be absorbed. The shunt helps prevent brain damage and alleviates symptoms associated with increased intracranial pressure.
