Incidence and characteristics of vascular trauma at a level 2 trauma center

Abstract

ObjectiveDespite the significant number of trauma patients treated at level 2 trauma centers (L2TCs) in the United States, most of the literature describing vascular trauma is from level 1 trauma centers (L1TCs). Currently, trauma center designation criteria do not require vascular surgery as a necessary component service. MethodsA retrospective chart review was performed for all trauma patients with a vascular surgery consultation seen at our L2TC between 2013 and 2018. Patient demographics, injury characteristics, and outcomes were collected and analyzed with descriptive statistics. ResultsOf the 3062 trauma patients evaluated at our L2TC, 110 (3.6%) had a vascular surgery consultation. Operative intervention was performed in 35.2% of consults, and 1.0% of all trauma patients had a vascular intervention. Average age was 57 years, and the majority were male (n = 75; 68.2%). Mean Injury Severity Score was 12.0 ± 9.6, and blunt injury (n = 77; 87.5%) was more common than penetrating (n = 11; 12.5%). The most common location of injury was the lower extremity (n = 23; 74.2%), followed by upper extremity (n = 3; 9.7%), chest (n = 2; 6.5%), neck (n = 2; 6.5%), and pelvis (n = 1; 3.2%). Endovascular interventions were performed by the vascular surgery service in 67.7% (n = 21) of all injuries. There was one amputation (3.2%) and one postoperative mortality (3.2%). ConclusionsAt our L2TC, postoperative morbidity and mortality rates at 30 days were substantially lower compared with previously reported data. However, mean injury severity score and the incidence of penetrating and polytrauma were also lower at our institution. Most patients were managed nonoperatively, but when they did require an operation, endovascular therapies were more commonly implemented. Vascular surgery should be considered an integral service in trauma level designation, and there is a need for further investigation of these outcomes in L2TCs.
