ABSTRACT
A 50-year-old man who had coronary artery bypass grafting (LITA-LAD, RA-RCA, SVG-OM-PL) 6 years previously was admitted with acute dissection of the aorta (DeBakey type I). Preoperative computed tomography showed that all coronary bypass grafts were patent. We replaced the graft of the ascending aorta and reconstructed the coronary artery bypass by re-sternotomy, circulatory arrest (rectal temperature 23.6°C), retrograde cerebral perfusion, and intermittent retrograde cardioplegia. Because a radial artery (RA) graft and a saphenous vein graft (SVG) each had intact orifices, we detached them together and attached the grafts back to the aortic graft wall. He was weaned successfully from cardiopulmonary bypass without difficulty and postoperative transthoracic echocardiography (TTE) showed good left ventricle (LV) function. Postoperative multidetector-row computed tomography (MDCT) showed that the RA graft and SVG were patent. By performing circulatory arrest and intermittent retrograde cardioplegia, we successfully protected the myocardial function of a patient with acute aorta dissection after a CABG and we reconstructed the graft without needing further coronary anastomosis.
