Treating a thoracic aortic aneurysm(TAA)after coronary artery bypass graft(CABG)surgery requires an appropriate surgical procedure to preserve the functional graft. We present a case of hybrid procedure of thoracic endovascular aortic repair combined with a redo off-pump CABG via median sternotomy. The patient was a 76-year-old man with a history of CABG and abdominal aortic replacement in a different country. Chest computed tomography revealed a saccular-shaped aortic aneurysm in the distal aortic arch with diameter of 5.6 cm. Coronary angiography revealed theLIMA graft was patent but anastomosed to the diagonal branch and the left anterior descending artery(LAD)was totally occluded and was opacified through the right coronary artery. Significant ischemic change in the anteroseptal wall suggested a requirement of surgical revascularization of LAD. The chest was opened via re-midsternotomy. Then the 3 arch vessels were reconstructed with a trifurcated artificial graft attached to the ascending aorta and coronary artery bypass grafting was performed on the beating heart. Finally, the aneurysm was excluded by introducing a stent graft through the graft to zone 0. The patient’s postoperative course was uneventful and he was discharged on postoperative day 16. A hybrid procedure via median sternotomy was useful in the surgery for TAA with the functional LIMA after CABG.
