BackgroundThe impact of vascular injuries on patient mortality has not been well evaluated in multi-trauma patients. This study seeks to determine (1) whether the presence of vascular trauma negatively affects outcome compared with nonvascular trauma (NVT) and (2) the utility of existing severity scoring systems in predicting mortality among vascular trauma (VT) patients.MethodsA retrospective review of our trauma database from January 2005 to December 2007 was conducted. Demographics, Injury Severity Scores (ISS), Revised Trauma Scores (RTS), Trauma Score-Injury Severity Scores (TRISS), Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, and mortality rates were compared. Control patients were selected from a matching cohort based on ISS. Comparisons were made between groups based on the above scoring systems. Statistical analysis used χ(2) analysis and Student t-tests.ResultsFifty VT and 50 NVT patients were identified with no significant differences in age, gender, mechanism of injury, ISS, RTS, or TRISS. The mean APACHE II score was higher in VT compared with NVT (12.3 vs 8.8, P < .05). Overall mortality was higher in VT compared with NVT but did not reach statistical significance (24% vs 11.8%, P = .108). VT patients with RTS score >5 had a higher mortality rate (26% vs 2.2%, P = .007). VT patients with an ISS score >24 had a higher mortality compared with NVT patients (61% vs 28.6%, P = .04). VT patients with an APACHE II score <14 also had a higher mortality rate (18.2% vs 0%, P = .007). Finally, VT patients with a TRISS probability of survival of >80% had a higher mortality rate (13.9% vs 0%, P = .05).ConclusionsIn multi-trauma patients, the presence of vascular injury was associated with increased mortality in less severely injured patients based on the RTS, TRISS, and APACHE II scores. These scoring systems underestimated mortality in patients with vascular trauma. Level of care and future trauma algorithms should be adjusted in the presence of vascular trauma.Copyright © 2011 Society for Vascular Surgery. Published by Mosby, Inc. All rights reserved.
