Abstract
Twelve years after receiving a renal transplant, a 50-year-old woman developed asthmatic symptoms. Chest CT revealed a descending thoracic aortic aneurysm. She had undergone percutaneous coronary intervention to treat the left anterior descending artery 10 years earlier. Coronary artery angiography revealed restenosis of the left anterior descending artery (99%, #6 in-stent). Because cardiopulmonary bypass may cause problems for transplanted kidney, we performed off-pump coronary artery bypass grafting (left internal thoracic artery to left anterior descending artery) and thoracic endovascular graft placement to treat the aortic aneurysm. Considering that the artery of the transplanted kidney was attached to the right iliac artery, and then the left common femoral artery was selected as the access root for GORE TAG® endografts (34 × 200 and 34 × 150 mm) (stentgrafts were deployed for the descending aortic artery). Postoperative angiography showed a patent bypass graft. Postoperative CT confirmed the absence of endoleaks. The postoperative course was uneventful, and she was discharged without complications. Ischemic heart disease and descending thoracic aortic aneurysm in recipients of kidney transplants can be treated using off-pump coronary bypass grafting and thoracic endovascular graft placement. The transplanted kidney was protected without using cardiopulmonary bypass (CPB).
