To investigate the factors influencing the length of surviva after elective repair of abdominal aortic aneurysm (AAA). we conducted aretrospective case study of 338 consecutive patients between 1980 and 1899 at our institute. Preoperative and intraoperative factors were analysed using the Cox hazards model. The hospital mortality rate was 1.2%. The survival rate was 81.0% at 5 years and 54.5% at 10 years. The free rate from cardiovascular related death was 90.0% at 5 years, and 72.5 % at 10 years. A univariate analysis demonstrated that risk factors affecting survival rate were age, arrhythmia, and untreated thoracic aneurysm. According to a multivariate analysis, the significant risk factors were age, arrhythmias, untreated thoracic aneurysm and renal dysfunction. Likewise risk factors affecting the free rate from cardiovascular related death were age, untreated thoracic aneurysm according to a univariate analysis, and age, untreated thoracic aueuzrsro, renal dysfunction, and ischemic heart disease according to multivariate analysis. However, there was no significant difference in survival rates between patients in their seventies and those in their eighties. These findings supported the elective AAA repair for octogenerians, but several preoperative factors including age influenced the long survival after elective AAA repair. It is important to continue proper management and appropriate follow up.
