Purpose: Endoluminal stent-graft repair for aortic aneurysms replaced some part of surgical correction because of higher success rate with lesser invasiveness and mortality. The purpose of study is to assess long-term mortality and clinical results of the endoluminal therapy in patients with aortic aneurysms which was performed at the various aortoiliac pathology last 14 years. Methods: Retrospective analysis was done on 141 patients (average age: 66.3 짹 10.1) who underwent stent-graft repair at our single center from July of 1994 to December of 2007. The indications of case selection were progression of aortic aneurysm despite adequate medical treatment, aortic diameter of 6 cm or more, or other medically intractable problems in either acute or chronic presentation. Results: Median follow-up duration was 3.1 years (2 months ~ 14 years, 4.1 짹 3.0 years). Locations of each lesion were abdominoiliac vessel (62.4%), thoracic aorta (16.3%), abdominal aorta (21.3%). Angiographic success, defined as immediate obliteration of target lesion without major endoleak or complete exclusion of aneurysm, was obtained in 134/141 (95.0%). Clinical success, defined as complete obliteration of the target lesion at follow-up without further interventional or operative management, was achieved in 128/141 (90.8%). Among these patients, 18 patients (12.8%) were expired due to aneurysmrelated, non-cardiovascular causes (5.7%), cardiovascular causes (3.5%), and cancer (1.4%). The cumulative survival rates at 2 years and 5 years were found to be 96.0% and 88.4%, using Kaplan-Meier methods. Conclusions: The outcome of endovascular stent-graft repair of aortic aneurysms was acceptable with a clinical success rate of 90.8% without acute procedure associated mortality or major complication. Endoluminal stent-graft repair should be considered as a safe and effective alternative treatment option of aortic aneurysm, particularly in patients with a high risk of surgical mortality or morbidity.
