Stereotactic Heavy-Particle Irradiation of Intracranial Arteriovenous Malformations
Microsurgical techniques have made more feasible the total excision of arteriovenous malformations (AVMs) located in previously inaccessible areas of the brain, and with acceptable rates of morbidity and mortality. Nonetheless, there are still many AVMs that cannot be treated surgically, either because they are located deep within the brain or because of their enormous size or relatively benign clinical presentation. From September 1980 to December 1984, we treated 75 patients who had AVMs of this particular group with combined methods of intraluminal embolization, surgical occlusion of the arterial feeding vessels, and/or partial excision of the AVM, followed by stereotactic heavy-particle irradiation.
