111 MCQs in Pathology Answer

The Correct option is B


Protruding atherosclerotic lesions in the thoracic aorta, often with superimposed mobile thrombi, are an important cause of embolic disease. During the last 6 years, the increasing use of transesophageal echocardiography has shown that atherosclerotic plaque in the thoracic aorta is a source of otherwise unexplained embolic events, including stroke, transient ischemic attack, and peripheral emboli.

An additional, different clinical picture-the classic atheroemboli syndrome-is associated with aortic atherosclerosis. This well-described syndrome consists of renal insufficiency, skin lesions, blue toes, and multisystem findings caused by embolic phenomena. It can occur spontaneously but frequently results from arterial manipulation, such as cardiac catheterization and aortotomy during coronary artery bypass surgery.
