Use of stents with medication coating for the treatment of occlusive-stenotic lesions of the superficial femoral artery

Abstract

Objective ‒ to analyze the results of endovascular revascularization of the femoropopliteal segment with drug-eluting stents. Materials and methods. Endovascular intervention was performed in 23 patients with stenotic lesions of the superficial femoral artery (SFA). Paclitaxel-eluting stents were used. There were 10 men (43.5 %), 13 women (56.5 %). The mean age of the patients was (66.0 ± 3.5) years. There were 16 (69.6 %) patients with diabetes mellitus type 2 and diabetic angiopathy, and 7 (23.4 %) patients had obliterating atherosclerosis of the arteries of the lower limbs. Critical ischemia of the lower extremities was diagnosed in 18 (56.5 %) cases, intermittent claudication ‒ in 5 (21.7 %). Isolated lesions of the femoral-popliteal segment were noted in 3 (13.4 %) patients, lesions of the iliac and femoral-popliteal segments ‒ in 4 (17.4 %), lesions of the femoral-popliteal and ankle segments ‒ in 16 (69.6 %). Results. Twenty (86.6 %) scheduled procedures for stenting of the SFA were technically successful. Among postoperative complications, 3 (13.04 %) patients had puncture site hematomas that did not require surgical evacuation. In 6 (26.1 %) patients, signs of reperfusion syndrome were observed, which were treated with conservative treatment. During follow-up period (3 months), there were no cases of reocclusion or clinically significant restenosis at the stented level. In 1 (5.0 %) case, a hemodynamically significant stenosis of the SFA was observed outside the implanted stent. The patient successfully underwent angioplasty of SFA stenosis. There were no «major» amputations during follow-up period. «Small» ankle amputations were performed in 7 (35.0 %) patients with diabetic gangrene, where endovascular revascularization of the femoro-popliteal and ankle segments was the stage of surgical treatment. Conclusions. Implantation of drug-eluting stents is an effective method of endovascular revascularization in patients with SFA lesions. To compare the results of implantation of drug-eluting stents with other methods of revascularization of the lesions of the femoro-popliteal segment, it is necessary to accumulate more data and increase the duration of the follow-up period.
