Abstract: Unruptured cerebral arteriovenous malformations often present with seizure. The mechanism of seizure can vary from effect of surrounding hemosiderin from subclinical hemorrhage, arterial steal, or venous congestion. Medical and surgical management should primarily focus on reduction of seizure symptoms and elimination or reduction of arteriovenous malformation rupture risk. Arteriovenous malformation treatment lowers seizure risk, and should be considered for patients in whom resection can be achieved with acceptably low morbidity and mortality. The exact approach chosen will depend on the size, location, and complexity of the arteriovenous malformation. This chapter discusses the pre-surgical evaluation and treatment by surgical resection (with adjunctive embolization) for patients presenting symptomatic with seizures from unruptured cerebral arteriovenous malformations.
