I just had angio. on Wed. which confirmed that I have a large dural av fistula involving the occipital artery. I am told the artery is very large. I have intense pulsation of the artery at the back of my head and very loud pulsatile tinnitus. I will meet with the docs on the 12th for treatment options. I am wondering if anyone else has experience with this type of dural fistula and, if so, what treatment options were proposed.
