Background The long‐term effectiveness of atherectomy treatment for peripheral arterial disease is unknown. We studied 5‐year clinical outcomes by endovascular treatment type among patients with peripheral arterial disease. Methods and Results We queried the Medicare‐linked VQI (Vascular Quality Initiative) registry for endovascular interventions from 2010 to 2015. The exposure was treatment type: atherectomy (with or without percutaneous transluminal angioplasty [PTA]), stent (with or without PTA), or PTA alone. The outcomes were major amputation, any amputation, and major adverse limb event (major amputation or any reintervention). We used the center‐specific proportions of atherectomy procedures performed in the 12 months before a patient's procedure as the instruments to perform an instrumental‐variable Cox model analysis. Among 16 838 eligible patients (median follow‐up: 1.3–1.5 years), 11% underwent atherectomy, 40% received PTA alone, and 49% underwent stenting. Patients receiving atherectomy commonly underwent femoropopliteal artery treatment (atherectomy: 65%; PTA: 49%; stenting: 43%; P |
