Advances in Management of Carotid Atherosclerosis

Abstract

Carotid artery stenosis is a common and potentially treatable cause of stroke. Stroke risk is increased as the degree of carotid stenosis increases, as well as in patients with neurological symptoms referable to the stenosed carotid artery. Carotid stenosis can be quantified by ultrasound imaging, magnetic resonance angiography, or conventional angiography. Medical treatment with platelet antiaggregants reduces stroke risk in some patients; other patients are best treated with carotid endarterectomy. Experimental treatments for carotid stenosis, including carotid angioplasty with or without stenting, are under investigation. We summarize the current literature and provide treatment recommendations for patients with atherosclerotic carotid artery disease.
