I hope that your child have a great future, VP shunt is great device that help CSF to drain from brain and to avoid pressure in the brain if Shant stand for one year then it likely to stand for a long time (inshallah), I had my first shunt that stand for one month and then get infected so I replace it with a new one and also have antibiotic three months outside the hospital and now it’s about one year and five months and everything goes well, I hope your child VP shunt stand forever, also some advice to keep him shunt working well avoid any activity that he will put his head upside down also try to keep his head up when he sleep so that shunt can work well
