| Popis: | Background Treatment of peripheral arterial disease (PAD) has become increasingly dominated by endovascular interventions. The short-term outcomes of endovascular therapy have been well-studied but late outcomes remain largely unpublished; in this series we report the late outcomes of primary nitinol stenting. Methods All patients undergoing primary nitinol stenting of the superficial femoral artery (SFA) and/or popliteal artery (PA) during a 10-year period by a single surgeon (S.K.) were reviewed. No attempts were made on patients with orificial or total occlusion of the SFA, PA, and proximal tibial arteries. Differences in primary patency, primary-assisted patency, secondary patency, and freedom from bypass were evaluated at one, five, and nine years. Results A total of 294 limbs in 240 patients were treated. 130 additional endovascular procedures were observed during the study period averaging to 0.16 endovascular interventions per limb per year. Primary patency in TASC A/B limbs at one, five, and nine years was 79%, 35%, and 19% respectively and in TASC C/D limbs was 62%, 11%, and 3% respectively. Secondary patency in TASC A/B limbs at one, five, and nine years was 96%, 81%, and 65% respectively and in TASC C/D limbs was 92%, 64%, and 41% respectively. Freedom from bypass in TASC A/B limbs at one, five, and nine years was 98%, 89%, and 85% respectively and in TASC C/D limbs was 95%, 78%, and 69% respectively. Five below the knee amputations were observed during the study period. Conclusions An endovascular first approach can be applied to the vast majority of femoropopliteal lesions. While the late outcomes of TASC C/D lesions are inferior to those of TASC A/B lesions, an endovascular first approach still provides durable outcomes. |
