712 Outcomes of Infrainguinal Stents in Peripheral Arterial Disease

Abstract Background Endovascular therapy is an established treatment for peripheral arterial disease. In aortoiliac disease, above the inguinal ligament, percutaneous transluminal angioplasty (PTA) + stent results in good long-term patency rates[1]. comparison, rates of PTA femoropopliteal below ligament are inferior, despite advancements technology[2]. Multi-level disease more common, lesions often longer length and re-stenosis remain high. There a paucity data outcomes infrainguinal stents therefore debate to what optimal strategy should be[3]. Method 5-year retrospective analysis 59 patients between 2014 2019 UK regional vascular centre. Patients with Rutherford Score 3 - 6 were treated by Vascular Surgeons Interventional Radiologists stent. Outcomes included at 6, 12, 24, 36 months, need revascularisation/reintervention, major amputation, death. Results 12% occluded 30 days 39% 12 months. 34% required further intervention (PTA, bypass, amputation) 7 out (12%) target limbs amputated. Conclusions Whilst demonstrates effective selection patients, it evident that work order identify best most clinically useful outcome measure.
