Embolization of Cerebral Arteriovenous Malformations: Part I-Technique, Morphology, and Complications

Abstract

In a series of AVMs, most of which were regarded as unsuitable for surgical excision, two-thirds were reduced to a size suitable for gamma knife treatment or totally occluded by embolization alone. The total complication rate was high, but the combined rate of death and complications affecting lifestyle was 8.0%, equal to approximately 3.2 years of natural history.
