The authors consider the tactical features of transcutaneous endovascular angioplasty in 110 patients with multiple arterial occlusive and stenotic lesions of the pelvis and lower extremities. A total of 299 arteries were operated on and desobliteration of stenoses and occlusions were performed. Five procedures of transcutaneous endovascular angioplasty: via transfemoral antegrade, transfemoral retrograde, transfemoral contralateral, transpopliteal, and transaxillary accesses were used alone or in combination. The tactics of transcutaneous endovascular angioplasty was determined by the nature, site, and extent of lesions, as well as the status of the distal arterial bed. Clinical positive results of transcutaneous endovascular angioplasty were obtained in 94 (85.4%) patients. Complications following endovascular interventions were encountered in 5 (4.6%) cases.

The authors analyse the results of endovascular angioplasty of the pelvic and lower limb arteries in 147 patients of various age suffering from arteriosclerosis obliterans. It was found that the results of endovascular angioplasty depended on the state of the lipid balance. The necessity for correcting the shifts in the lipid metabolism is shown. The article evaluates the results of dyslipidemia correction by dietotherapy, pharmacotherapy, and operation for partial ilio-shunting in patients with arteriosclerosis obliterans of the pelvic and lower limb arteries. The efficacy of the listed methods of treatment are analysed according to the severity of dyslipidemia.

The paper outlines the analysis of immediate and late outcomes of transcutaneous transluminal angioplasty (TTA) in 147 patients with atherosclerosis obliterans of the lower extremities. The study has revealed that age and dyslipidemia as TTA risk factors fail to affect the immediate outcomes in the early postoperative period. There is a positive correlation of the reocclusion time after TTA and the age and lipid metabolic disturbances in patients with atherosclerosis obliterans of the lower extremities in long-term periods. The paper provides strong evidence for that it is essential to correct dyslipidemias in order to make TTA results better in these patients.

Endovascular interventions were performed in 36 patients with multiple occlusive-stenotic lesions of main arteries of the pelvis and lower extremities. Femoral retrograde, antegrade and contralateral accesses were used. The importance to observe main principles of roentgenendovascular surgery is stressed such as organ preservation, atraumatic character, shorter time of staying of the patients at the hospital. The authors show advantages of one-step reestablishing of blood flow in all parts of the vascular bed subject to endovascular dilatation. The authors note that in certain clinical situations the roentgenendovascular surgery for multiple obliterating lesions must be performed in two steps and through different accesses.
