Purpose: Most outcome studies of bypass surgery are limited to five years of follow-up. However, as human life expectancy has increased, analyses of more long-term outcomes are needed. The aim of this study is to evaluate 10-year outcomes of anatomical bypasses in aortoiliac occlusive disease.
Methods: From 1996 to 2009, 92 patients (82 males and 10 females) underwent aortic anatomical bypasses to treat aortoiliac occlusive disease at Samsung Medical Center. The patients were reviewed retrospectively. Kaplan-Meier survival analyses were performed using PASW ver. 18.0 (IBM Co).
Results: A total of 72 patients (78.3%) underwent aorto-femoral bypasses (uni- or bi-femoral), 15 patients (16.3%) underwent aorto-iliac bypasses (uni- or bi-iliac), and 5 patients (5.4%) underwent aorto-iliac and aorto-femoral bypasses. The overall primary patency rates of the 92 patients were 86.2% over 5 years and 77.6% over 10 years. The 10-year limb salvage rate and overall survival rate were 97.7% and 91.7%, respectively.
Conclusion: The overall patency rates of bypass graft and limb salvage rates decreased as time passed. The analysis of results after bypass surgery to treat arterial occlusive disease will be needed to extend for 10 years of follow-up.
