A case of multiple coronary artery aneurysms in a patient with an abdominal aortic aneurysm and bilateral popliteal artery aneurysms is reported. As diagnosis and treatment of coronary artery disease become more aggressive, a higher incidence of detection of coronary artery aneurysms in conjunction with peripheral vascular lesions is likely. The role of coronary sinus cardioplegia in minimizing the risk of embolization from the coronary aneurysms during surgical repair is emphasized.
