Abstract
A 66-year-old man who had previously undergone coronary artery bypass grafting (CABG) was admitted to our institution for surgical treatment of a ruptured aortic arch aneurysm. He had three patent bypassed grafts including the left internal thoracic artery (LITA) to the left anterior descending artery (LAD), complicated by left ventricular dysfunction. Coronary angiography performed 1 year after the initial surgery revealed total occlusion of the LAD. In addition, the aneurysm was located next to the LITA; therefore, there was a significant risk of injury to the LITA during intraoperative dissection. For such a complicated and challenging case, we successfully performed a total aortic arch replacement using a Y-shaped composite saphenous vein graft (SVG) for the administration of cardioplegic solution to establish effective myocardial protection. This procedure, by which effective myocardial protection can be achieved, is a useful treatment option for aortic arch surgery after CABG with a patent LITA graft.
