The patient was a 70-year-old man who underwent a graft replacement of the descending thoracic aorta for a DeBakey type mb dissecting aneurysm. Digital subtraction angiography per formed on postoperative day IS revealed an abdominal aorta occlusion caused by enlargement of the false lumen. A new intimal defect was found in the a ortic wall 2 cm distal to the suture line, the cause of which was suspected to be clamp injury during the initial operation. Graft replacement of the abdominal aorta was subsequently carried out. Postoperatively, he had no co mplications, and digital subtraction angiography showed excellent reconstru ction of the abdominal aorta.
