I have 2 VP shunts and 1 LP shunt. I have Hydrocephelus, Pseudo Tumor Cerebrai and Chiari Malformation. I have had 2 of my shunts for 7 years now. Knock on wood, all has been going good with the shunts. Getting a good nsgt to put them in is important. I believe most of the problems come from not putting them in correctly. I see them in a positive way for they have saved my life. I am now totally used to them and no one can tell I have them.
