Abstract Purpose: Endovascular stent-graft treatment for true aneurysms of the descending thoracic aorta is a valid and effective alternative to conventional surgery. A review of our experience with 21 consecutive patients is reported and technical considerations are discussed. Methods: Twenty-one patients (mean age 73 years) with true aneurysms of the descending thoracic aorta (n = 14) or contained rupture (n = 7) were treated between October 1999 and July 2001. Seven patients (33%) underwent emergency endovascular procedure. Postoperatively, the patients were followed with CT scans at 1, 3, 6, and 12 months. Follow-up, which averaged 17 months, was 100% complete. Thirty-day results: No conversions to open repair were necessary. Two patients died (10%), one of acute intestinal ischemia and the other because of multiorgan failure. Four patients showed endoleaks immediately after stenting. Two patients required new endovascular stentgrafts, while the remaining two were treated conservatively. Besides endoleaks, eight major complications occurred in six patients (two stroke, two paraplegia, two respiratory insufficiency, and one renal failure). Mid-term results: Three more patients died during the follow-up period. One patient died of heart failure after a complicated postoperative course, 91 days after stenting. The second patient died because of aortic rupture, 139 days after stenting. The third patient died of heart failure, 15 months after the endovascular procedure. The remaining 16 patients are alive and have been regularly controlled by CT scans. No late migration or endoleaks have been detected. In all the survivors, the size of the aneurysm was unchanged or diminished. Conclusions: Treatment of descending thoracic aortic aneurysms by endovascular stentgraft devices has good early and mid-term results. More accurate selection of patients may further reduce mortality and morbidity.
