THE PROTECTIVE STATUS OF SUBTOTAL OBLITERATION OF ARTERIOVENOUS MALFORMATIONS AFTER RADIOSURGERY

Abstract

Subtotally obliterated AVMs are different from other partially obliterated AVMs, with a 0% bleeding rate. Their complete obliteration is a function of delay of appearance on follow-up angiography. Invasive follow-up and further treatment of these AVMs do not seem warranted.
