A shunt in adults can last for 6 years. Though medical practitioners say it is difficult to predict how long a shunt can last, studies show that all shunts either need to be revised or replaced after a period of 6 years.
A ventriculoperitoneal (VP) shunt is placed inside one of the brain’s ventricles to divert fluid away and restore CSF’s normal flow and absorption. The entire procedure for this surgical treatment takes more or less than 90 minutes.
