Abstract
Purpose
To evaluate long-term clinical outcomes after revascularization by bypass graft versus Fogarty balloon catheter in acute blunt popliteal artery injury and identify risk factors contributing to amputation.
Methods
A retrospective review was conducted in patients treated for acute blunt PAI between 2011 and 2019. Inclusion criteria were patients who underwent bypass graft and Fogarty balloon catheter. The cumulative limb salvage rate was calculated by the Kaplan–Meier test and compared with Breslow–Wilcoxon test. Cox proportional hazard model was performed to estimate the potential risk factors for amputation. Receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value for the potential risk factors.
Results
The overall limb salvage rate was 60.4% (29/48), including 24 patients (66.7%) in bypass graft, and 5 patients (41.7%) in Fogarty balloon catheter with mean follow-up of 5 years (range, 2–10 years). Among amputees, 15 patients (15/19, 78.9%) received primary amputation due to vascular failure or severe soft tissue damage, and 4 received secondary amputation because of chronic bone infection or neurologic deficit. Kaplan–Meier curves showed patients who received Fogarty balloon catheter had significantly higher amputation rate than those received bypass graft, with a hazard ratio of 3.801 (95% CI: 1.162–12.43, p = 0.009). In addition, Cox proportional hazard model revealed that MESS was the only independent risk factor for patients developing amputation, and the optimal cut-off value of MESS was 8.
Conclusion
Five-year outcome demonstrated that Fogarty balloon catheter is not a safe procedure and has significantly higher amputation rate in severe blunt PAI. MESS is the only risk factor for amputation.
