Abstract: Cerebral arteriovenous malformations are a rare cause of hemorrhage or seizure. They may occur anywhere in the brain and vary considerably in size, arterial and venous drainage, and the degree to which they involve eloquent cortex. Decision-making in terms of treatment depends on an analysis of the expected natural history, the expected number of at risk years, and the anticipated risks and efficacy of treatment. Treatment of unruptured arteriovenous malformations for the prevention of adverse sequelae often requires a multimodality approach, including consideration of the roles of surgical resection, endovascular embolization, and stereotactic radiosurgery. This chapter discusses the diagnosis and management of unruptured cerebral arteriovenous malformations.
