[The biocompatibility testing of various types of nonorganic implants].

Impact of living organism on nonorganic materials, which are applied for the implants manufacturing, was studied. There was established, that organism of a recipient patient actively effects on exogenic material, destroying its superficial layer and forming the connective tissue capsule around the implant. The implant surface may start to dissolve selectively as a result of aseptic inflammation, keeping around, in such a situation it become necessary to remove the prostheses, which have lost their function.

[Remote results of endoprosthesis of the infrarenal aorta aneurysm].

Endovascular endoprosthesis of infrarenal aorta aneurysm (EEIAA)--is miniinvasive highly technological method of treatment of a life-threatening disease. The rate of the endovascular interventions conduction for aortal aneurysm enhances every year in the world, the prosthesis construction and operative technique are upgrading constantly. The experience of the EEIAA endoprosthesis in 75 patients, aged 51-80 years old, 70 men and 5 women, was presented.

[Anesthesiological support during performance of endovascular prosthesis for the infrarenal aorta aneurysm].

The results of treatment of 10 patients, suffering the abdominal aorta aneurysm, using the third generation bifurcational prosthesis Excluder, are presented. Endoprosthesis was performed under local infiltrating anesthesia (LIA) and light sedation, in one observation the LIA was incidentally changed to general anesthesia and artificial lung ventilation. In the early postoperative period the complications did not occur.

[Prophylaxis and treatment of a pulmonary artery thromboembolism].

Experience of treatment of 103 patients with an acute thromboembolism (TE) of a. pulmonalis (AP) was analyzed. According to clinic, angiographical and hemodynamical investigations data the indications for performance of operative and conservative treatment depending on degree of the pulmonary blood flow disorder were substantiated.

[Application of clexane for prophylaxis of thromboembolic complications in surgery of morbid obesity].

The results of comparative clinical application of low-molecular heparin Clexan vs heparin for the thromboembolic complications prophylaxis in surgical treatment of morbid obesity were summarized.

[Simultaneous revascularization of the myocardium and lower extremities due to dissipated atherosclerosis].

In 18 patients with the cardiac coronary arteries and the lower extremities main arteries atherosclerotic affection the simultaneous aortocoronary shunting in concurrence with the lower extremities revascularization were conducted. The mortality was 5.5%.

[The evaluation of the elastic properties of the arterial wall by ultrasonic study data in patients with atherosclerotic vascular lesions].

Ultrasonic scanning method in a real scale of time was used in examination of 10 patients with abdominal aorta (AA) aneurysm, 10-with arterial hypertension (AH), 10-with obliterating atherosclerosis of the lower extremities vessels (OALEV) without AH and practically healthy controls aged 32-45 years. AA aneurysm and OALEV diagnosis was made according to the ultrasonic investigation and roentgen-contrast angiography data obtained. The statistically significant (P < 0.

[Surgical treatment of multiple occlusions of the aortic arch arteries].

The results of treatment of 174 patients with lesions of the arteries of the aortic arch are presented. Multiple lesions of the coronary arteries were revealed in 78 patients, of the brachiocephalic trunk--in 45, their combination--in 52. In patients with the ischemic heart disease, in average, 3,4 aortocoronary shunts were placed.

[The therapeutic procedure in thromboembolism of the pulmonary artery].

Clinical symptomatology, ECG, roentgenography, echocardiography, blood biochemistry, angiopulmonography with manometry of the pulmonary artery and right heart compartments were used to diagnose in 14 patients (age: 25-65 years) massive and submassive pulmonary artery thromboembolism. The angiopulmonographic index exceeded 18 points. Treatment included embolectomy, medical therapy (heparine, indirect anticoagulants), thrombolytic agents (celiase) and symptomatic therapy.

[Intragastric blood flow in the etiology of duodenal ulcer--new aspects of surgical treatment].

In the experiment on dogs and in patients with duodenal ulcer disease, it was established that the regulation of acid production besides the vagal nerves was mediated by the intragastric gastrin transport with the blood flow. A method of preoperative diagnosis of the intensity of intragastric blood flow permitting to define more accurately the indications for the choice of a method for surgical treatment has been developed. Supplementation of the selective proximal vagotomy with circular mucosectomy at the boundary between the antrum and body of a stomach enhances the effectiveness of operation due to reduction of the antral gastrin influence on the acid-producing zones of the stomach.
