Update on Gamma Knife Radiosurgery for Arteriovenous Malformations

Abstract

  Cerebral arteriovenous malformation (AVM) treatment aims to eliminate intracranial hemorrhage risks and prevent new neurological deficits. Gamma Knife radiosurgery has been widely used in the treatment of AVM because a steady growth in scientific publications has established the role of Gamma Knife radiosurgery. Most patients with AVM suitable for Gamma Knife radiosurgery have relatively small- to medium-sized AVMs located in critical structures of the brain and high risks for alternative managements, including surgery and endovascular embolization. The author describes the outcomes of patients who underwent Gamma Knife radiosurgery for multiple types of AVM and reports subgroup analyses to evaluate total obliteration, risk of hemorrhage, and complications of AVM Gamma Knife radiosurgery.
