Abstract
Atherectomy is experiencing increased interest from endovascular specialists as a therapeutic treatment in the peripheral arteries. Long studied in the coronary vasculature, atherectomy has several theoretical advantages that make it uniquely suited for the peripheral circulation. In particular, infra-inguinal peripheral arterial disease experiences physiologic stresses and forces that have made traditional percutaneous coronary treatments such as angioplasty and stenting not as successful. Restenosis has been a major problem for angioplasty and stenting alone. The SilverHawk atherectomy device has favorable short-term data but important longer-term data are limited and need further study. Laser atherectomy also has favorable applications in niche patients but the number of studies is limited. Unfortunately, athero-ablative technologies for peripheral arterial disease require more definitive objective data regarding 12-month and longer-term outcomes in order to obtain widespread scientific acceptance.
