Background: Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability., Methods: A multicenter, retrospective review of patients with subclavian or axillary artery injuries from January 1, 2004, to December 31, 2014, was completed at 11 participating Western Trauma Association institutions. Statistical analysis included χ, t-tests, and Cochran-Armitage trend tests. A p value less than 0.05 was significant., Results: Two hundred twenty-three patients were included; mean age was 36 years, 84% were men. An increase in computed tomography angiography and decrease in conventional angiography was observed over time (p = 0.018). There were 120 subclavian and 119 axillary artery injuries. Procedure type was associated with injury grade (p < 0.001). Open operations were performed in 135 (61%) patients, including 93% of greater than 50% circumference lacerations and 83% of vessel transections. Endovascular repairs were performed in 38 (17%) patients; most frequently for pseudoaneurysms. Fourteen (6%) patients underwent a hybrid procedure. Use of endovascular versus open procedures did not increase over the duration of the study (p = 0.248). In-hospital mortality rate was 10%. Graft or stent thrombosis occurred in 7% and graft or stent infection occurred in 3% of patients. Mean follow-up was 1.6 ± 2.4 years (n = 150). Limb salvage was achieved in 216 (97%) patients., Conclusion: The management of subclavian and axillary artery injuries still requires a wide variety of open exposures and procedures, especially for the control of active hemorrhage from more than 50% vessel lacerations and transections. Endovascular repairs were used most often for pseudoaneurysms. Low early complication rates and limb salvage rates of 97% were observed after open and endovascular repairs., Level of Evidence: Prognostic/epidemiologic, level IV.

Introduction: A child's risk of developing cancer from radiation exposure associated with computed tomography (CT) imaging is estimated to be as high as 1/500. Chest CT (CCT), often as part of a "pan-scan," is increasingly performed after blunt trauma in children. We hypothesized that routine CCT for the initial evaluation of blunt injured children does not add clinically useful information beyond chest radiograph (CXR) and rarely changes management., Methods: Pediatric (<15 y) trauma team evaluations over 6 y at an academic Level I trauma center were reviewed. Demographic data, injuries, imaging, and management were identified for all patients undergoing CT. Effective radiation dose in milliSieverts (mSv) was calculated using age-adjusted scales., Results: Fifty-seven of 174 children (33%) undergoing CT imaging had a CCT; 55 (97%) of these had a CXR. Pathology was identified in significantly fewer CXRs compared with CCTs (51% versus 83%, P < 0.001). All 7/57 (12%) emergent or urgent chest interventions were based on information from CXR. In 53 children (93%), the CCT was ordered as part of a pan-scan, resulting in a radiation dose of 37.69 ± 7.80 mSv from initial CT scans. Radiation dose was significantly greater from CCT than from CXR (8.7 ± 1.1 mSv versus 0.017 ± 0.002 mSv, P < 0.001)., Conclusions: Clinically useful information found on CCT had good correlation to information obtained from CXR and did not change patient management, however, did add significantly to the radiation exposure of initial imaging. We recommend selective use of CCT, particularly in the presence of an abnormal mediastinal silhouette on CXR after a significant deceleration injury., (Copyright © 2013 Elsevier Inc.
