Hi J.! My daughter also has a VP Shunt for her hydrocephalus. She also has spina bifida. Her shunt was placed when she was 2 weeks old and she needed a complete revision at 2 1/2 months. SO SCARY! She is now almost 2 and hasn't had any other issues. I thank God for that, as I have heard other stories like yours. My hubby's cousin had a tumor that caused her hydrocephalus. She had a shunt for YEARS with no issues, then about a year ago she had 3 or 4 replacements in one year. It was very hard on her, as she is a single mom in her early 20's. You are not alone. I know with spina bifida, it can cause chiari malformation, which can cause a person to throw up a lot. Make sure your doctor is looking into all the possiblilities. We have Kaiser, and they are just great. We live in the Sac area, but her special needs are taken care of by the Kaiser in Oakland. Let me know if you want to chat more, ok? take care!!
