[Atherectomy in Peripheral Artery Disease: Current and Future]

Abstract

Atherectomy has become a promising treatment option for peripheral artery disease caused by diabetes mellitus or end-stage renal disease. Atherectomy refers to the removal of atheromatous tissue by mechanical method, resulting in an enlarged lumen of the treated blood vessel. Based on this method, the term is limited to the percutaneous minimally invasive approach, and there are currently two types of atherectomy devices available in Korea. The increased prevalence of atherectomy has led to the concept of "vascular preparation" and a new treatment concept of "leave nothing behind." Various studies have proven the safety and effectiveness of atherectomy; however, there are some limitations. We need to remain focused on patient selection and subsequent large-scale research.
