[The catamnesis of patients with stenosis of the internal carotid artery who have undergone carotid endarterectomy and of unoperated patients].

Investigation of catamnesis of 100 patients with atherosclerotic carotid artery stenosis (50 were operated and 50--non-operated) revealed, that in some cases carotid endarterectomy prevented repeated cerebrovascular disorders and had prophylactic significance. The frequency of repeated stroke in the group of non-operated patients was 3 times higher than in the group of operated patients. In operated cases no more TIAS were observed, but they persisted in non-operated cases.

[Endarterectomy in arteriosclerotic stenosis of the internal carotid artery].

The efficacy of carotid endarterectomy (CE) was estimated in 50 patients with stenosis of the internal carotid artery due to atherosclerosis. In addition to neurological investigations, all the patients were subjected to USDG of the head vessels, cerebral angiography and CT of the brain. Patients with the signs of cerebral circulation disorders or those who suffered ischemic brain stroke with a reversible neurological deficit were the most prospective candidates for CE.

[Indications for cerebral revascularization through the system of the external carotid artery].

The paper analyzes the study into the specific features of cerebral hemodynamics in patients with internal carotid artery occlusion. The study was performed by using Doppler ultrasound techniques. It revealed three different types of collateral blood flow of the brain according to the function of orbital anastomosis.

[Surgical treatment of vertebrobasilar insufficiency].

The clinical experience of the Department of Vascular Surgery of the Vishnevsky Institute of Surgery, covering a period between November, 1983 and December, 1987 was analysed. Problems of the etiology and pathogenesis of vertebrobasilar insufficiency and the peculiarities of choosing the methods for surgical correction according to the extent and localization of the occlusive lesions were studied. The sequence and volume of the surgical intervention in patients with isolated and combined affections of the vessels of the vertebrobasilar and carotid channels are discussed.
