atherectomy
Pronunciation: ath-er-EK-toh-mee
Surgical procedure to remove atherosclerotic plaque from blood vessels using specialized cutting devices.
Full Definition
Atherectomy is a minimally invasive vascular procedure that involves the mechanical removal of atherosclerotic plaque from arterial walls using rotating cutters, lasers, or other specialized devices. This procedure is typically performed as an alternative to balloon angioplasty when plaque is heavily calcified or when precise plaque removal is required. The procedure helps restore blood flow through narrowed arteries and is commonly used in peripheral arterial disease and coronary artery interventions.
Usage
Usage note: Often confused with arteriotomy (surgical incision) or arthrectomy (joint surgery). Emphasize the plaque removal aspect.
