The optimal revascularization strategy for Patients with subclavian and coronary artery disease has not yet been established. A few reports exist regarding the management of patients who have both occlusive disease of the subclavian arteries and coronary artery disease. We present a case simultaneously treated with CABG and subclavian artery revascularization. The prosthetic graft was brought to the distal segment of the subclavian artery through the clavicle while keeping the pleura intact and anastomosed to the superior surface of the artery. Aortosubclavian bypass with coronary artery bypass may be an effective option for patients with coexisting subclavian and coronary artery disease.
