My daughter had her shunt for 16 years and had no problem. Over spring break we found she had a whole in the lower shunt tube so the neuro put in another one leaving the rest of it alone. Morgan had severe headaches afterwards and vision trouble. We went a little over a week before we saw the doctor. We had to call him because she started throwing up. We went to the hospital and they tapped her shunt and he could get very little fluid out. He also saw a slight increase in her ventricles. He put her in the hospital and decided to go in again. The next morning he tapped her again to see if there was a change and there was not. He took her to surgery and came out and told us the shunt was working fine. He said that she probably is not adjusting to the new pressure change because her shunt tube is shaped different. I am really concerned that they are missing something else. Morgan can't stand the laying flat and has a problem feeling dizzy when she gets up. He kept us two days in the hospital. Has anyone else heard anything like this? Could it really be that her body is just trying to except the new pressure? Please help
