[Emergency Redo Off-pump Coronary Artery Bypass Surgery after 22 Years in an Elderly; Report of a Case].

An 84-year-old male presented to our hospital with recurrent angina. He had undergone coronary artery bypass with a saphenous vein graft to the left anterior descending branch (LAD) 22 years before. Coronary angiography showed occulusion of the proximal LAD and significant stenosis of the saphenous vein graft. An emergency redo operation was conducted using the left internal thoracic artery for LAD revascularization. The postoperative course was uneventful and the patient was discharged in a week. Emergency redo coronary bypass surgery can be indicated even in octogenarians who are resistant to medical treatment.
