Shunt Operation Statistics■About 40,000 shunt-related operations are performed every year in the US for hydrocephalus—that averages out to one every 13 minutes and over 100 every day. ■Shunt operations for hydrocephalus cost over $1 billion a year in the US. ■50% of shunted individuals require a revising operation within two years. A second treatment option is a surgical procedure called endoscopic third ventriculostomy (ETV). An endoscope is used to puncture a membrane in the floor of the third ventricle creating a pathway for CSF flow within the cavities in the brain. ETV is an important alternative to shunting for obstructive hydrocephalus and may be useful in other cases as well.

Unlike many other operations in which the risks are highest during the surgical procedure, most problems associated with shunting occur weeks or even years afterward. Shunt obstruction and malfunction occur in approximately one third of children in the first year after a shunt-related operation and studies have shown that ETVs can close up after time. We cannot overstate the importance of learning the signs and symptoms of treatment failure. Staying in close contact with neurosurgeons if you have a shunt or an ETV is critical.
