title: Angiographic contribution to the problem of enlargement of cerebral arteriovenous malformations.
abstract: From a series of 325 cases of cerebral arteriovenous malformations, seven patients are reported presenting a change in size of the malformation in the course of several years. The enlargement of the malformation is documented by four vessel cerebral angiography, and haemodynamic and histopathological characteristics are discussed. Serial four vessel cerebral angiography is strongly indicated for accurate diagnosis, and radical excision of these malformations with the microtechnical method is advocated.
