Angiographic Long-term Follow-up Data for Arteriovenous Malformations Previously Proven to Be Obliterated after Gamma Knife Radiosurgery

Abstract

There is a small possibility that AVMs may reappear after having been totally occluded after radiosurgery, especially in pediatric patients. Segmental narrowing in normal arteries after radiosurgery is a benign condition that rarely progresses and does not produce clinical symptoms.
