Concomitant Aortoaxillary Bypass and Coronary Artery Bypass Grafting

Abstract

The optimal revascularization strategy for patients with subclavian and coronary artery disease has not been established. This study assessed the mid-term clinical outcome of concomitant aortoaxillary bypass and coronary artery bypass grafting in 5 patients. A ring-reinforced polytetrafluoroethylene graft was attached to the ascending aorta and led to the proximal segment of the axillary artery via the pleural cavity. Patients were followed up for 2–10 years (mean, 5.4 ± 3.4 years). Postoperative aortography and angiography demonstrated patent aortoaxillary and coronary bypass grafts in the short-term follow-up of all patients. Two patients with Takayasu aortitis needed re-operations for recurrent angina and annuloaortic dilatation. Another patient required removal of the aortoaxillary bypass graft because of infection, and subsequently underwent a left femoroaxillary bypass one year after the original procedure. Subclavian steal phenomenon did not occur. Aortoaxillary bypass with coronary artery bypass may be an effective option for patients with co-existing subclavian and coronary artery disease.
