A Case of Off-Pump CABG for Unstable Angina with High-Risk Complications Secondary to Aortitis / 日本心臓血管外科学会雑誌

A 66-year-old woman suffered from an effort angina attack and visited our clinic. Coronary angiography revealed severe stenosis in the ostium of bilateral coronary arteries. Preoperative computed tomography (CT) demonstrated severe calcification of the aorta and aneurysmal change in the thoracic descending aorta. Off-pump CABG was performed without mechanical cardiac support using composite grafts of the right internal mammary artery and a saphenous vein graft. Graft patency was intraoperatively confirmed by SPY as well as by coronary multi detector-row computed tomography (MDCT) 3 months postoperatively.
