Spaintay- What about a programmable shunt? I too have slit ventricles and have had a lot of procedures bc of it. Finally my neurosurgeon decided on a programmable shunt to see if this would help w some of the high and low pressure symptoms. It definitely has. I have had the pressure changed quite a few times because it was less invasive then a tap or guessing game. Also- mine has a reservoir; I can sometimes feel whether I am high or low by the way the reservoir feels. Hope you feel better!
