title: Hemispheric arteriovenous fistulae with giant venous dilation.
abstract: A direct fistula between cerebral cortical arteries and venous channels may result in an impressive aneurysm-like, saccular dilation of the venous portion. We had the opportunity to treat two children with this rare arteriovenous malformation, with excellent results. The controversy on the classification and treatment of this pathology is discussed briefly.
