1-1 Atherosclerosis of Aorta
Note the numerous raised plaques covering most of the initmal surface of the aorta. Complications associated with severe atherosclerosis of the aorta include narrowing and/or occlusion of the orifices of vessels arising from the aorta, embolization of plaque material, and superimposed thrombosis with embolization. Aortic aneurysms may occur in association with atherosclerosis.

Atherosclerosis of Aorta (42000-52140)
The section demonstrates an atherosclerotic plaque overlying the aortic media. The core of the plaque is composed mainly of lipid-laden macrophages. Stippled calcification is also evident. The lamellated surface of the plaque is the fibrous cap.
