My daughter was having odd symptoms (stomach aches, terrible sinus trouble, panic like feelings & personality changes) 3 years ago Jan. that led her Dr. to do an MRI in Apr 04. They found a non-ruptured AVM. We were told her symptoms had nothing to do with the AVM. Just a miraculous fluke. They advised surgery. She had the AVM embolized first ( it took two times to do it) the following week she had her surgery. The Avm was 3cm by 4 cm. Surgery wasVery successfull. No visible problems. All her symptoms went away right after her surgery. On follow up angio they found a small risidual they could not get, it is in-operatable. They recommended gamma knife, which she had in Nov. 04. For the last 3 years she has been perfectly normal & active. In Apr 07 her symptoms came back. They did an MRI which looked normal. We were told it had nothing to do with her AVM, so we started checking into other possibilities that could be causing her symptom. Her family Dr. did a complete blood work. Normal. He put her on anxiety meds, no changes. Antibiotics for sinuses. No change. We went to an ear, nose & throat specialist, he did CT scan, she has sinusitus. They have her on sinus meds, does relieve sinus symptoms, but not the others. After many conversations with her neurologist he felt she might be having seizures (teenagers have a very hard time describing their symptoms). The stomach ache she always complained of never caused her to throw up or have diarrea. She finally told us it felt as if her stomach was coming up her throat. Well she had an EEG and it showed abnormal waves on her left side, They say she is having partial seizures. She was probably having them before. (so the symptoms did have something to do with her AVM) They put her on Trileptal. She has been on it for 1 week. We are not seeing any changes yet, but I know it can take a couple weeks. We are waiting patiently. We have the best Doctors. All of them have been great. I am just wondering how common this is, long term effects, odds of controling these kinds of seizures, & is there any support groups out there for teens & moms who have been through these kinds of problems. This has been very emotionaly draining for both of us. thanks for any input.
