Abstract
Introduction: Aortoiliac occlusive disease and iliofemoral occlusion are impact patient quality of life, cause limb loss and mortality. The aim of this study was to investigate the long-term clinical outcomes of arterial bypass, and the factors associated with the outcomes. Method: This retrospective chart/image review included all types of arterial bypass procedures performed for suprainguinal arterial occlusion during January 2004 to December 2017. The primary outcome was the primary patency. The secondary outcomes were the secondary patency, amputation-free survival, overall survival and the factors associated with the outcomes. Result: A total of 135 patients (107 males) were included. The median age was 65 years. The 1-year, 5-year, and 10-year primary patency rates were 74.3%, 65.7%, and 55.6%, respectively, with independent predictors of poor outcomes being underlying cerebrovascular disease (p = 0.003) and postoperative graft infection (p = 0.016). Secondary patency rates at 1-year, 5-year, and 10-year intervals were 90.1%, 87.1%, and 77.8%, respectively, with independent predictors of poor outcomes being underlying cardiovascular disease (p = 0.013) and postoperative acute kidney injury (p = 0.010). Amputation-free survival rates at 1-year, 5-year, and 10-year intervals were 77.1%, 71.6%, and 66.0%, respectively, with the independent predictor of poor outcome being preoperative foot infection (p = 0.013). Overall survival rates at 1-year, 5-year, and 10-year intervals were 84.4%, 58.6%, and 35.3%, respectively, with independent predictors of poor outcomes being chronic kidney disease (p = 0.030) and postoperative myocardial infarction (p = 0.018). However, antiplatelet therapy emerged as an independent predictor of favorable overall survival outcomes (p = 0.034). Conclusion: Our results showed the primary patency rates of arterial bypass to be relatively low at our center; however, most grafts could be saved with high secondary patency. Both disease-associated factors and patient condition-associated factors were found to influence the outcomes of this fragile patient population.
