Embolization of Cerebral Arteriovenous Malformations

Effective treatment of cerebral arteriovenous malformations (AVMs) requires a multidisciplinary approach that combines microsurgical resection, endovascular embolization, and radiosurgery. Embolization is most commonly used to reduce the arterial supply before surgery or radiosurgery. Additional indications include an attempt to achieve cure through complete AVM obliteration, targeted treatment to eliminate high-risk features, and subtotal occlusion to palliate symptoms caused by an otherwise incurable AVM. In all cases, the risks and benefits of treatment must be weighed carefully when formulating a treatment strategy. Ultimately, for optimal management of cerebral AVMs, treating centers should have access to physicians experienced in open cerebrovascular surgery, endovascular embolization, and radiosurgery.
