[Combined surgical treatment of associated lesions of the major arteries of the head].

Concurrent affection of the main arteries of the head is the cause of vascular cerebral insufficiency in more than half of the patients, which makes necessary combined operations on the extra- and intracranial arteries. The sequence of the operations is determined by the degree of the threat of occlusion of the stenosed artery or by the side on which the cerebrovascular insufficiency is manifested. Information on the regional cerebral blood flow and the results of ultrasonic dopplerography and computed tomography are additional criteria for determining the sequence and the terms of the operations. Experience in 61 combined operations allows the authors to consider them to be an effective method for the surgical management of concurrent affections of the main arteries of the head.
