%X Axillosubclavian vessel injury is rare, with most cases occurring after penetrating trauma. A prior database (2002每2006) analysis demonstrated an overall limb loss rate of 2.9%, with no difference between isolated arterial axillosubclavian vessel injury and combined artery/vein axillosubclavian vessel injury. Given increases in advanced vascular surgical techniques, as well as improved multidisciplinary care and expeditious diagnosis with computed tomography angiography, we hypothesized the national rate of limb loss in patients with arterial axillosubclavian vessel injury has decreased. In addition, we attempted to identify current predictors for limb loss in arterial axillosubclavian vessel injury. Finally, we hypothesized that combined artery/vein axillosubclavian vessel injury, as well as associated brachial plexus injury will have a higher risk for limb-loss and mortality compared to isolated arterial axillosubclavian vessel injury. A retrospective analysis of the National Trauma Data Bank was performed between 2007 and 2015. All patients ≡ 18 years of age with arterial axillosubclavian vessel injury were included. The primary outcome was limb loss. After a univariable logistic regression model identified significant covariates, we performed a multivariable logistic regression for analysis. Of the total 5,494,609 trauma admissions, 3807 patients had arterial axillosubclavian vessel injury (<0.1%). Of these, 3137 (82.4%) had isolated arterial axillosubclavian vessel injury and 670 (17.6%) had combined artery/vein axillosubclavian vessel injury. The overall limb loss rate was 2.4% (from 2.9% in 2006, pˋ=ˋ0.47). After adjusting for covariates, independent risk factors for limb loss included a combined artery/vein axillosubclavian vessel injury (odds ratioˋ=ˋ3.54, confidence intervalˋ=ˋ2.06每6.11, pˋ<ˋ0.001), blunt mechanism (odds ratioˋ=ˋ7.81, confidence intervalˋ=ˋ4.21每14.48, pˋ<ˋ0.001), open repair (odds ratioˋ=ˋ2.37, confidence intervalˋ=ˋ1.47每3.82, pˋ<ˋ0.001), and open proximal humerus fracture (odds ratioˋ=ˋ8.50, confidence intervalˋ=ˋ4.97每14.54, pˋ<ˋ0.001). An associated brachial plexus injury was not associated with limb loss (pˋ=ˋ0.37). Combined artery/vein axillosubclavian vessel injury was associated with higher risk for mortality compared to isolated arterial axillosubclavian vessel injury (odds ratioˋ=ˋ2.17, confidence intervalˋ=ˋ1.73每2.71, pˋ<ˋ0.001). The national rate of limb loss in trauma patients with arterial axillosubclavian vessel injury has not changed in the past decade. A combined artery/vein axillosubclavian vessel injury is an
