The Particulars: Predictors of patency after endovascular treatment of femoropopliteal atherosclerotic arterial occlusive disease are not well known.
Data Breakdown: A study reviewed 180 limbs in 170 patients with lesions in the femoropopliteal arterial segment, 91 that received stents and 89 that received percutaneous transluminal angioplasty (PTA). Freedom from target vessel revascularization or major amputation was 81% at 2 years and 68% at 3 years; for Trans-Atlantic Inter-Society Consensus (TASC) A/B lesions, corresponding rates were 86% at 2 years and 74% at 3 years, compared with 73% and 60%, respectively, for TASC C/D lesions. Renal impairment and longer stent length were the predictors most frequently associated with re-intervention.
Take Home Pearl: TASC class, renal insufficiency, and longer stent length appear to be important predictors of poor outcomes in patients undergoing endovascular treatment of femoropopliteal atherosclerotic arterial occlusive disease.
