Objective: In patients with critical limb ischemia who undergone revascularization procedures, the assessment of risk factors that may affect the postoperative outcome is of great importance. The main objective in this study is to assess the utility of two specific risk scores, the Finnvasc score and the modified Prevent III score.Methods: We evaluated the applicability of these two risk scores in 150 patients who undergone an unilateral infrainguinal surgical revascularization procedure. The receiver operating characteristic curve analysis was used to estimate the predictive value of the scoring methods. A comparison between the risk scores, determine the areas under the curve. Medium-term prediction ability was analyzed for both scoring methods.Results: The area under the curve of Finnvasc score for predicting amputation was 0.739 (95%CI:0.661-0.807) and of the modified PIII score 0.713 (95%CI:0.633-0.784); for restenosis we obtained 0.528 (95%CI:0.444-0.611), respectively 0.529 (95%CI:0.445-0.612) and for thrombosis 0.628 (95%CI:0.544-0.706) and 0.556 (95%CI:0.472-0.638), demonstrating that the Finnvasc score performs better in overall prediction. Heart failure is a strong independent predictor of amputation (p=0.0001, OR=26.90; 95%CI:5.81-124.2), restenosis (p=0.0003, OR=4.80; 95%CI:1.96-11.8) and mortality (p=0.01, OR=7.16; 95%CI:1.33-38.52).Conclusions: The accuracy of the two risk scoring methods in predicting the medium-term outcome of patients undergoing surgical infrainguinal revascularization is acceptable. The Finnvasc score is easier to be applied to the characteristics of our patients.
