Extracranial vertebral arteriovenous fistulae of non traumatic origin are extremely rare. The authors report two cases of spontaneous vertebro-vertebral arteriovenous fistulae associated with fibromuscular dysplasia. They discuss the relation-ship between arteriovenous fistulae and fibro-muscular dysplasia, and the specific problems of treatment in these two cases.
The authors report 144 post-operative angiographic controls of carotid and vertebral artery surgery performed from 1979 to 1983. They describe the most common post-operative appearances they have observed and compare them to those reported in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
