Two cases of off-pump coronary artery bypass grafting combined with abdominal aortic aneurysm repair.
Two cases of coronary artery disease coexisting with abdominal aortic aneurysm were treated with off-pump coronary artery bypass grafting combined with repair of the aneurysm. The first patient was a 67-year-old man exhibiting a large pulsating abdominal mass. Abdominal computed tomography demonstrated a 9-cm aneurysm and coronary angiogram revealed a 90% stenosis of the obtuse marginal branch for which percutaneous transluminal angioplasty could not be performed. He underwent simultaneous single coronary artery bypass grafting without cardiopulmonary bypass, and bifurcated graft replacement. The second patient was a 71-year-old man who had acute myocardial infarction, and one month later underwent coronary angiogram which revealed three vessel disease in the coronary artery. Computed tomography revealed a 4-cm aneurysm, and angiography showed a 90% stenosis of the left renal artery. He underwent a single stage operation that involved three coronary artery bypass grafting without cardiopulmonary bypass, straight graft replacement, and reconstruction of the left renal artery using the saphenous vein graft. The postoperative course was uneventful in both cases. We currently recommend a single stage operation involving off-pump coronary artery bypass grafting.
