How is hydrocephalis treated surgically?

I myself have hydrocephalaus due to an arachnoid cyst on my pituitary gland(located in your brain) There are a couple of different ways to treat it. One way is to insert a device called a shunt it is a long tube that is inserted in you brain and the other end goes to your styomach and the excess fluid is drained from you head to your stomach. I have 2 vp shunts, there are a few problems with them they can clog or break in which case you would need a revision or a new shunt. An alternative treatment for obstructive hydrocephalus in selected patients is the endoscopic third ventriculostomy (ETV), whereby a surgically created opening in the floor of the third ventricle allows the CSF to flow directly to the basal cisterns, thereby shortcutting any obstruction, as in aqueductal stenosis. This may or may not be appropriate based on individual anatomy I hope this helps Sincerely Kevin
