Simultaneous coronary artery bypass grafting and ascending aorta bifemoral bypass in small aorta syndrome.

A 55-year-old man with severe coronary artery disease and aortoiliac occlusive disease with small aorta syndrome was admitted to our department with angina pectoris and bilateral claudication. Intravenous subtraction angiography showed total occlusion of the right common iliac artery and 99% stenosis of the left common iliac artery with a markedly hypoplastic infrarenal aorta only 9 mm in diameter. It also revealed 90% stenosis at the origin of the left subclavian artery. Coronary angiography showed total occlusion of the left anterior descending artery and 90% stenosis of the circumflex artery. Simultaneous coronary artery bypass grafting and an ascending aorta-bifemoral bypass were conducted using an in-situ right internal mammary artery graft, an autologous saphenous vein graft, and a Y-figured expanded polytetrafluoroethylene graft. Postoperative angiography showed grafts to the coronary and bifemoral arteries were patient. This combined procedure is useful for patients with coronary artery disease and aortoiliac occlusive disease, especially in those with small aorta syndrome.
