Abstract
Coronary artery aneurysm (CAA) is defined as a localized coronary artery dilatation, which can be saccular or fusiform, and exceeds the diameter of the normal adjacent segments or the diameter of the patient’s largest coronary vessel by 1.5 times. CAA is an uncommon disease with an incidence of 0.3–4.9% in large angiographic series. CAA is observed most commonly in the right coronary artery, and least frequently in the left main coronary artery. It has been demonstrated that atherosclerosis is the main cause of CAA in adults, and Kawasaki disease in children and adolescents. The natural history and prognosis of CAA remain obscure, and management of the published recommendations are based on anecdotal experience. The most prevalent consequence of aneurysms in the coronary arteries is formation of a thrombus with distal embolization, vasospasm or vessel disruption at the site of wall injury. Therefore, therapeutic management in CAA involves both prevention of thromboembolic complications and percutaneous or surgical closure of the aneurysm entry. We report the cases of four patients who were treated surgically for CAA (non-Kawasaki disease) in our institute.
