Abstract:
We describe the repair of a descending thoracic aortic aneurysm (saccular type, maximal size 85 mm) with an endovascular stent-graft in a 69-year-old man with chronic renal failure. The graft consisted of a self-expanding Z-stent covered with a woven polyester graft. An angiogram obtained intraoperatively showed complete thrombosis of the aneurysm. One month after the procedure, a contrast-enhanced computed tomographic (CT) scan showed thrombosis of the aneurysmal sac. A follow-up CT scan obtained 18 months after operation confirmed that the aneurysm had disappeared.
