Management of significant atherosclerotic carotid artery disease: review of literature

Sibasankar Dalai, Aravind V. Datla


Stroke is the third leading cause of death and disability in the world. Carotid artery stenosis due to atherosclerosis accounts for 20 to 30% of all strokes. The patients can be asymptomatic or present with a transient ischemic attack or stroke. Diagnosis is based primarily on imaging modalities like carotid Doppler, CT (Computed tomography) angiogram, MR (Magnetic resonance) angiogram or DSA (Digital subtraction angiogram). Treatment options include optimal medical therapy, carotid endarterectomy-touted as the gold standard for treating significant carotid stenosis; and carotid artery stenting, whose safety and efficacy have undergone significant improvements due to technological advances in the field. We presented a review of the literature outlining the various aspects of atherosclerotic carotid stenosis and the findings of several randomized controlled trials conducted to settle the debate between endarterectomy and stenting for carotid stenosis.
