[Carotid endarterectomy and endovascular angioplasty with stenting in patients with atherosclerotic stenoses and occlusions of the internal carotid artery].

The authors made a comparative assessment of carotid endarterectomy and endovascular angioplasty with stenting in patients with atherosclerotic lesions of the carotid arteries. The authors consider that indications to stenting and carotid endarterectomy are identical in patients with stenose and occlusions of the carotid arteries. Contraindications to angioplasty of carotid arteries are determined.

[Detection of Borrelia miyamotoi in ticks Ixodes persulcatus from Russia].

Unfed adult Ixodes persulcatus ticks from five regions of Russia were examined to analyze the distribution and diversity of Borrelia miyamotoi. DNA of B. miyamotoi was found in 1.

[Role of extra-intracarotid anastomosis in the surgical treatment of chronic cerebral ischemia].

About 500 patients with ischemic brain lesions were studied. Out of them 201 patients underwent 230 operations: 140 extra-intracarotid bypass (EIB) and 90 various interventions on brachiocephalic branches. The study of cerebral hemodynamics by examining blood pressure in the central artery of the retina and middle cerebral artery during surgery, comparison of these findings with those of Doppler sonography and angiography made the authors conclude that EIB improves cerebral hemodynamics, and in some cases it is the only intervention able to improve the status of patients.

[Response of the pro- and antioxidant systems to plasmapheresis in patients with advanced atherosclerosis obliterans of the legs].

The effects of fractional apparatus plasmapheresis in a volume of 25% of circulating blood plasma on the processes of lipid peroxidation and on the antioxidant defence system parameters were studied in 31 patients with ischemia of the lower limbs, stage III-IV. It has been shown that plasmapheresis induces elevation of ceruloplasmin activity and superoxide dismutase activity of blood plasma, lowers the ratio of lipid oxidation to lipid peroxidation products simultaneously with intensification of lipid peroxidation that leads to regeneration of biological membranes of the body.

[Surgical treatment of patients with arteriosclerotic disorders of cerebrovascular circulation].

An analysis of the complex examination of 170 patients with ischemic diseases of the brain has been made. Seventy patients were operated upon. Operations either in brachiocephalic branches or extra-intracarotid shunts were performed corresponding to the three established levels of the injuries.

[Restorative operations using microsurgical technics in abruption of large segments of the upper limb].

Ten observations of replantations of the hand, forearm and shoulder after their traumatic abjunction are analyzed. Seven patients had complete reimplantation. Failures resulted from prolonged anoxia of the abjuncted segment or from extensive lesions to soft tissues of the replant.

[Use of the microsurgical technics in the treatment of occlusive diseases of the main arteries of the lower limbs].

Microsurgical techniques permit high-quality intervascular anastomosis in small and mid-caliber arterial surgery of lower extremities. This improves immediate outcomes in surgical patients with obliterating atherosclerosis of lower extremities. Microsurgical femoropopliteal autovenous shunting in patients with ischemia of the third or fourth degree (by Fontana) reduced the rate of shunt thrombosis from 37 to 27%.

[Surgical treatment and prevention of myocardial infarct].

In modern surgery of coronary arteries both surgical therapy of early stages of acute infarction and its surgical prophylaxis in preinfarction conditions seem to be quite feasible. 100 consecutive operations for ischemic heart disease are analysed. The principal type of surgery is a mammary coronary anastomosis.
