Cleveland Clinic is # 1 in Gamma Knife Surgery. I had 3 AVM’S, on of which was inoperable, but treated with the Gamma Knife. I can send you the Chief Gamma Knife Dr & you could send him a copy of your MRI and angiogram results.
My Gamma knife was 9/14 of this year.
Numb head, tintinus, head ache and still recovering. Best wish and many blessings!
