Objective: The aim of this study was to determine factors affecting the long-term survival of subjects with aortic aneurysm (AA). Methods: We included 294 Korean patients aged ≥30 years who were hospitalized from 1994 through 2004. Diagnosis was confirmed in 267A subjects (75.8% with abdominal only AA (AAA) and 24.2% with thoracic AA (TAA)) by computed tomography angiography in Samsung Medical Center, Seoul, Korea. AA repair direct operation or percutaneous endovascular AA repair (Revascularized group) was performed in 60.3% of the total patients. Death data were obtained from all participants between 1994 and 2009. Results: The mean age of AA subjects was 68.7 (±8.1) years. The proportion of males was 82%. Five- and 10-year survival rates were 89.8% and 82.6%, respectively. The 5- and 10-year survival rates were 92.3% and 84.9% in revascularized group and 86.4% and 79.5% in non-revascularized group, respectively. Adjusted hazard ratios were 1.11 {95% confidence interval (CI) 1.04-1.21} in ages and 3.07 (95% CI 1.26-7.90) in smoking for AA. Conclusions: Age and smoking contributed to death in Korean AA patients. In addition, the 10-year survival rate for AA patients in Korea was over 80%.
