Abstract
Stroke is the third leading cause of death in industrialized nations, with an annual incidence of about 700,000 stroke events. Ischemic strokes constitute 80–86% of all strokes. It has been estimated that ≥50% carotid stenosis may be responsible for up to 25% of all ischemic strokes. This chapter highlights the basic anatomy and pathophysiology of the extracranial carotid system. The common carotid bifurcation and the proximal internal carotid artery account for 50% of the lesions. The most common cause of cerebral ischemic events is embolic phenomena, primarily arterial in origin (carotid) and secondary to cardiac sources. The work-up of patients presenting with asymptomatic carotid bruits or TIAs should include initial carotid duplex scanning. Duplex scanning of the carotid bifurcation provides a highly accurate method of identifying significant lesions of the internal carotid artery as well as of separating lesions into general pathologic categories. Carotid CTA/MRA may be added to the work-up of these patients, particularly if the carotid duplex ultrasound is inadequate, and conventional arteriography is usually reserved for use prior to CAS. Management of these patients includes medical treatment alone or CEA/CAS with medical treatment.
