- W4323657890 abstract "Background: Infrainguinal vascular injuries (IIVIs) are emergencies involving both functional and vital prognosis. The choice between saving the limb or doing a first-line amputation is difficult even for an experienced surgeon. The aims of this work are to analyze early outcomes in our center and to identify predictive factors for amputation. Methods Between 2010 and 2017, we reviewed retrospectively patients with IIVI. The main criteria for judgment were as follows: primary, secondary, and overall amputation. Two groups of potential risk factors of amputation were analyzed: Those related to the patient: age, shock, ISS score and those related to the lesion: mechanism, above or below the knee, bone lesions, venous lesions and skin decay. A univariate and multivariate analysis were performed to determine the risk factor(s) independently associated with the occurrence of amputation. Results Fifty-seven IIVIs were found in 54 patients. The mean ISS was 32,3 ± 21. A primary amputation was performed in 19%, and secondary in 14% of cases. Overall amputation rate was 35% (n = 19). Multivariate analysis reveals that the ISS is the only predictor of primary (P = 0.009; odds ratio (OR):1.07; confidence interval (CI):1.01–1.12) and global (P = 0.04; OR:1.07; IC:1.02–1.13) amputation. A threshold value of 41 was selected as a primary amputation risk factor with a negative predictive value of 97%. Conclusions The ISS is a good predictor of the risk of amputation in IIVI. A threshold of 41 is an objective criterion helping to decide for a first-line amputation. Advanced age and hemodynamic instability should not be important in the decision tree.
