[Clinical picture and diagnosis of arteriovenous malformations of the posterior cranial fossa].

An anatomo-surgical classification of arteriovenous malformations of the posterior cranial fossa (PCF) is suggested, based on angiography and computer-aided tomography findings with due consideration for adequate surgical approaches to the defect. Conditions of blood supply and drainage are described with regard to localization of the malformation in the PCF structures. Analysis of the neurologic symptoms in PCF arteriovenous malformations permitted a conclusion on a comparatively rare correlation between the symptoms and the localization of the malformation in a certain PCF structure.
