Surgery for distal aortic arch aneurysm with a patent left internal mammary-to-coronary artery graft; report of a case

We report a case of 62-year-old male who suffered from a distal aortic arch aneurysm developed 5 years after coronary artery bypass grafting (CABG). Preoperative angiography revealed a distal arch aneurysm and a patent left internal mammary artery (LIMA) graft. Graft replacement of the total aortic arch was performed using a 4 branched graft. After the re-median sternotomy, cardiopulmonary bypass was established with ascending aortic perfusion and right atrium (RA) drainage. Myocardial protection was achieved with root cold blood cardioplegia and LIMA continuous cold blood perfusion. Distal anastomosis was performed under selective cerebral perfusion and during deep hypothermic circulatory arrest. Postoperative course was satisfactory and the patient was discharged without complications.
