Presented in the article are the results of studying antiaggregate activity of acetylsalicylic acid and clopidogrel in a total of 36 patients suffering from various-severity chronic arterial insufficiency of lower limbs on the background of atherosclerosis obliterans. The study was conducted prior to treatment for correct selection of a particular antiplatelet agent. The obtained results showed that clopidogrel was not always more efficient than acetylsalicylic acid, since there is individual sensitivity of each patients to a particular antiplatelet agent. Therefore, an individual approach is necessary to conservative therapy of arterial insufficiency of lower limbs. For some patients it is preferable to administer clopidogrel, for others - acetylsalicylic acid. In a series of cases combined treatment is justified, while some patients having low sensitivity to both acetylsalicylic acid and clopidogrel require careful selection of alternative agents influencing other thrombocyte receptors.

Presented herein are the results of treating a total of sixty patients suffering from atherosclerosis obliterans of the lower limbs with degree IV chronic ischaemia according to the Fontain-Pokrovsky classification and accompanied by pyonecrotic alterations. The patients were subdivided into two clinically matching groups, each comprising 30 subjects. All patients after two-week conservative preparation underwent various reconstructive surgical operations performed on major arteries of the lower limbs. The local preoperative treatment was of two different types, i. e. consisting of Levomecol ointment used in the control group patients and Metrogyl 1% topical gel applied in the study group patients. Sampled before treatment, inoculations of the wound discharge demonstrated predominantly anaerobic flora in all patients, with the number of bacterial strains having dramatically decreased once Metrogyl gel 1% had been used, whereas application of Levomecol did not significantly influence the structure of the microbial profile. Following surgical treatment we had to perform high amputation of the lower limb in 5 patients of the control group, whereas in the study group patients only one patient required amputation at the foot level. Hence, prior to carrying out reconstructive vascular interventions in patients presenting with pyonecrotic lesions of lower extremities it is preferable to perform debridement of the necrotic foci using topical antibacterial agents, one of which may be Metrogyl 1% gel.

The paper analyses diagnosis and treatment outcomes for 20 men aged from 55 to 76 with lower limb arteriosclerosis obliterans. Based on exhaustive laboratory and instrumental diagnostic data the authors conclude that 10-days course of Vazaprostan (20 mkg per day) for patients with IIb stage of chronic lower limb arterial insufficiency yields not only improvement in tissue metabolism, but a reduction of peripheral vascular resistance as well. Thus such therapy can be used for preoperative care before reconstructive vascular interventions in order to reduce the risk of implant thrombosis in early postoperative period.
