Chances are if your vision is being affected, then you will be put as a priority. When I had vision issues, I was put into surgery the next day. But anyways, I'm a girl, so my experience with the shaving hair thing is a little different. The two neuros I had before the one I have now would shave a good bit of hair. Not my whole head, not even enough to notice unless the wind was blowing. But for a guy who has short hair, it would of been more difficult. My neuro is really good about shaving as little hair as possible. Now that doesn't mean after you see what hair they shaved you won't decide to just shave your head anyways, but it will be your decision.

Oh and you will definitely be out. They definitely knock you out for shunt revisions, no matter how minor. Hope everything works out great for ya! ~Melissa~
