Abstract

Aneurysms of the thoracic aorta are still potentially life-threatening situations. The conventional operation is still associated with morbidity. Endovascular stent graft repair offers an alternative to conventional operation for management of aortic diseases. Our aim was to report our experience with endovascular stent graft repair of thoracic aortic aneurysms.Between November 2002 and October 2005, endovascular stent graft repair was performed in 26 patients: post-traumatic aortic aneurysm (n=4), Type B dissection (n=3) and descending thoracic aortic aneurysm (n=19). The deployed stent graft systems were Talent-Medtronic (n=14) and Excluder-Gore (n=12).Successful deployment of the stent grafts in the appropriate position was achieved in all patients. There was neither hospital mortality nor paraplegia. Late and non-procedure related death occurred in only one patient (3.8%). An average of 40% shrinkage of the aneurysmal space was observed. There was no early mortality and endoleaks. The median intensive care unit and hospital stay times were 1 and 7 days (range 4-13 days), respectively. Post-operative computed tomography scans were obtained in all patients and complete thrombosis was observed in the false lumen of dissecan aneurysms (n=3) and sac of saccular aneurysms in 25 patients. Mean follow up time was 17.1+/-5.4 months.Endovascular stent graft treatment for treatment of thoracic aorta aneurysm, Type B dissection and traumatic disease of the thoracic aorta is technically feasible. Although the short and mid-term results are encouraging the long term results will determine the future of this treatment.
