[Remote results of surgical management of chronic cerebrovascular insufficiency].

The work was aimed at studying the remote results of reconstructive operations performed on brachiocephalic arteries in a total of 1,483 patients presenting with chronic cerebrovascular insufficiency. The findings obtained from our experience confirmed that carotid endarterectomy up to now remains the gold standard of treatment for both symptomatic and asymptomatic patients suffering from haemodynamically significant lesions of carotid arteries, requiring, however, timely performance and consequent active follow up of the patients involved.

[Our experience in surgical management of internal carotid artery ocсlusion].

Analysed in the article are the outcomes of surgical management in a total of 42 patients diagnosed as having occlusive lesions of the internal carotid artery. Also studied is efficacy of the operation - resection and ligation of the internal carotid artery, endarterectomy from the common and external carotid arteries with the application of a dilating patch onto the external carotid artery in occlusion of the internal carotid artery in patients with endured ischaemic stroke, depending on severity of neurological deficit and the time having elapsed since the operation performed. Also investigated are peculiarities of cerebral haemodynamics in patients with occlusion of the internal carotid artery and haemodynamic alterations during the stages of surgical treatment. The obtained findings confirm efficacy of reconstructive operations in both prevention of relapsing stroke and surgical rehabilitation.

[Damage to craniocerebral nerves in reconstructive surgery of carotid arteries].

Reconstructive operations on aortic arch branches appear to be the most efficient method of preventing acute and chronic impairments of cerebral circulation. Iatrogenic lesions of the craniocerebral nerves deteriorate the course of the immediate, and especially the remote postoperative period, decreasing quality of life and social status of the patients after endured carotid reconstructions. The authors analysed herein the outcomes in a total of 562 patients after endured carotid artery surgery for atherosclerosis or pathological tortuosity. The authors examined the incidence rate, patterns and risk factor of damage to the craniocerebral nerves in all the patients. Comprehensive prevention of damage to the craniocerebral nerves was carried out in a total of 412 patients from the Study Group and was aimed at excluding or decreasing intensity of the eff ect of the eliminable risk factors. The proposed measures made it possible to decrease the rate of lesions of craniocerebral nerves from 18.7 to 6.9% and to substantially improve the postoperative patients' quality of life.

Diagnostics and surgical treatment of pathological deformation of the carotid arteries.

The most effective way of preventive maintenance of sharp and chronic disturbances of brain blood circulation are reconstructive operations on branches of an arch of an aorta. Pathological deformation meets far quite often in clinical practice and is the reason of cerebral-vascular insufficiency of various degree, including ischemic strokes. Research objective - improvement of diagnostics and tactics of treatment of the patients with pathological deformation of carotid arteries. 132 patients have entered into research with various kinds of pathological deformation. Have been made 143 reconstructive operations. Indications to operative treatment revealed by means of duplex investigation and angiography. At the same time defined hemodynamic changes on carotids with an obligatory estimation of a condition intracranial vascular channel. By the indication to operative treatment of the given category of patients it is considered: hemodynamic significant pathological deformations of an internal carotid, pathological deformation of an internal carotid in a combination with embologenal plaque, pathological deformation of an internal carotid with all types of atherosclerotic plaques narrowing a vessel gleam on 60% and more, in the presence of symptoms of cerebral-vascular insufficiency, especially at transient ischemic attacks and at an ischemic stroke. Positive clinical effect has been reached at 100% of patients with I and II degree chronic vascular-brain insufficiency, at 80,6% of patients with chronic vascular-brain insufficiency of III degree, and at 45,8% of patients which in the anamnesis have transferred sharp infringement of brain blood circulation.
