The present work was aimed at demonstrating possibilities and prospects of using covered stent grafts in treatment of patients with embolism-hazardous parietal thrombi, embolism-endangered stenoses, and occlusions of peripheral arteries. Using stent grafts covered with non-woven materials, including PTFE films ("Hemobahn endograft" and "JOSTENT Peripheral Stent Graft") in the arteries of the iliac and femoropoplietal segments, makes it possible to avoid not only acute and delayed occlusions, but to use a PTFE-covered stent graft as a means of isolating the intima from the blood flow, as a method of "inhibiting" intimal hyperplasia in the stented arterial segment. The article deals with clinical follow-ups of patients with embolism-dangerous atherosclerotic stenoses and occlusions of iliac arteries, who underwent successful implantation of covered stents into the affected segments of the arterial bed. These findings demonstrably show high efficacy of using methods of endografting in clinical situations wherein surgical treatment is associated with increased risk.

KEY WORDS: atherosclerosis, arterial occlusion, embolism-dangerous plaques, covered stents, grafts.
