National trends and variability of atherectomy use for peripheral vascular interventions from 2010 to 2019.

Objective: Small, older studies have suggested that the use of atherectomy devices has become common in peripheral vascular interventions (PVIs) despite the paucity of strong clinical guidelines. We analyzed the 10-year trends in the use of atherectomy for PVIs across the United States and identified the main predictors of atherectomy use.

Methods: Using the Vascular Quality Initiative registry, we identified all patients who had undergone endovascular PVIs for occlusive lower extremity arterial disease from 2010 to 2019.
