Carotid plaque characterisation by IVUS-VH during carotid stenting: the "eyes wide shut" between plaque morphology and symptoms

Abstract

Stroke is the third most common cause of death in North America and ever year approximately 700,000 new strokes are reported in the United States. Seventy-five percent of these occur in the distribution of the carotid arteries. Among strokes of a thromboembolic etiology, carotid occlusive disease is the most common cause. As many as 150,300 stroke-related fatalities are documented annually, with a total cost for the health-care system of approximately $ 18 billion per year. This review will focus on the different pathomorphologic aspects of carotid plaque, outlining the similarities and differences with the coronary plaque, with particular attention on how intravascular imaging may contribute to a better stratification of the patient treatment.
