Trends in Utilization and Outcomes of Orbital, Laser, and Excisional Atherectomy for Lower Extremity Revascularization.

Atherectomy use has increased, driven primarily by orbital atherectomy. Despite significant variation in perioperative outcomes, there were no differences in 1-year outcomes among the different modalities when used for treating isolated femoropopliteal disease. In isolated tibial disease treatment, excisional atherectomy was associated with higher 1-year primary patency compared with orbital atherectomy and decreased major ipsilateral amputation rates compared with laser atherectomy. These differences warrant further investigation into the comparative effectiveness of atherectomy modalities in various vascular beds.
