Is there any way to stop needing your vp shunt forever?

VP Shunt. Some patients have maintained the ability to reabsorb spinal fluid and the primary problem is a blockage within the pathways in the brain. In those situations, a 3rd ventriculostomy can be performed to redirect CSF around the blockage. Occasionally, there are patients who are found to have a broken shunt but without redeveloping hydrocephalus, essentially "outgrown the need for the shunt".
Unlikely. The original indication dictates the need and the permanence.
