Cerebral arteriovenous fistulae.

Dural arteriovenous fistulae (dAVFs) are diverse, complex lesions that share the common feature of arteriovenous shunting without an intervening nidus. In this chapter, the ensuing discussion is organized by dAVF location, followed by further consideration of less common, distinct types of dAVFs-carotid cavernous fistulae, pial arteriovenous fistulae, and vein of Galen malformations. For each lesion type, epidemiology, clinical presentation, imaging findings, classification considerations, and treatment options are discussed.
