What is a shunt revision?
If your child has a shunt in place, it may stop working properly. A shunt that is not working properly will need a part or all of it replaced. Doctors call this surgical procedure a revision. When a shunt is not working properly, it is because of one of the following reasons: • Particles or tissue may enter the shunt and block the flow of cerebral spinal fluid (CSF). • The shunt may become disconnected or broken, so that the CSF no longer drains into the right place. • Your child may have outgrown the shunt. • Over-drainage: the shunt is draining more CSF than it should. • Under-drainage: the shunt is not draining enough CSF. • Shunt infection.
