Methods: Twenty-eight patients (26 males, 2 females; mean age 66.8 years; range 41 to 80 years) who underwent endovascular stent-graft therapy between January 2010 and June 2013 were retrospectively analyzed. One of the aneurysms was a pseudoaneurysm occurred following aortic coarctation surgery, one was type 3 chronic dissecting aneurysm, and the others were degenerative aneurysms. The aneurysm was on the arcus aorta in two patients, thoracoabdominal in three patients, thoracal in eight patients, and infrarenal in the rest. The mean aneurysm diameter was 68.1 mm (range, 45 to 102 mm).

Results: One patient had post-procedural type 1 endoleak and one patient had type 2 endoleak due to lumbar artery. One patient required femorofemoral bypass due to graft branch occlusion, one patient developed hypoesthesia and pain in the lower limb, and one patient had chronic renal failure. Three patients died in the early postoperative period. Late-term mortality was observed in five patients. The mean duration of follow-up was 15.2 months (range, 3 to 30 months).

Conclusion: We were unable to reach favorable results of endovascular interventions reported in low-risk patients in our study including high-risk patients. We believe that endovascular therapies should be administered to high-risk patients who are anatomically suitable, while non-use of any intervention may be a favorable option in asymptomatic patients.
