What is the main purpose of the endarterectomy procedure?

The main purpose of the endarterectomy procedure is to remove atherosclerotic plaque from the inner lining of an artery to restore optimal blood flow. This procedure is particularly beneficial in situations where there is significant blockage due to plaque buildup, which can lead to various complications, including ischemia or stroke.

While the procedure is commonly associated with carotid arteries due to high-profile cases of carotid endarterectomy aimed at preventing strokes, it can also be effectively utilized for obstructed arteries in the lower extremities. In cases where peripheral artery disease results in such blockages, endarterectomy can help bypass or clear the obstruction, thus enhancing blood flow to the legs and feet.

Other options refer to limitations or specific applications of endarterectomy. While endarterectomy is often used for carotid stenosis, it is by no means limited to that application. Its relevance extends to other vascular regions, including the lower extremities, making it a viable option for obstructed peripheral arteries. Infrarenal arteries are generally addressed with different interventions, such as angioplasty or bypass surgery, rather than endarterectomy. Lastly, for renal arteries, treatment typically focuses on angioplasty or stenting rather than endarterectomy, given the different pathophysiological
