My husband has hydrosifalus and went through 4 brain surgries 1 was on his neck to remove scare tissue which opened the spinal fluid flow to his brain, now they said his pressure was to high. Then he went through a surgery to put a shunt in and it got infected so they took it out, and year later they put it in again. Now his brain is shifting it went from 3mm to 6mm to the left and the shunts on the right. Does anyone know the outcome of this if the doctors don't know the cause or won't take the shunt out.
