endarterectomy
Pronunciation: end-ar-ter-EK-to-mee
Surgical procedure involving removal of atherosclerotic plaque from the inner lining of an artery to restore normal blood flow.
Full Definition
Endarterectomy is a surgical technique used to treat arterial occlusive disease by removing atherosclerotic plaque and the diseased intimal layer from the inside of an artery. The procedure involves making an arteriotomy (opening in the artery), carefully dissecting and removing the plaque along with the intima and inner portion of the media, then closing the artery, often with a patch to prevent narrowing. Common sites include the carotid arteries (carotid endarterectomy or CEA) and femoral arteries. This procedure can effectively restore blood flow and reduce the risk of stroke or limb ischemia when performed on appropriately selected patients.
Usage
Usage note: Often abbreviated as CEA when referring to carotid procedures; ensure anatomical site is clearly specified.
