Background Endovascular repair (ER) of axillosubclavian arterial injuries is a minimally invasive alternative to open repair (OR). The purpose of this study was to compare the outcomes of ER vs OR. Methods A retrospective study was performed of patients who sustained axillosubclavian arterial injuries admitted to two high-volume academic trauma centers between 2003 and 2013. Patients undergoing ER and OR were matched according to 25 different demographic and clinical variables in a 1:3 ratio using propensity scores. The primary outcome was in-hospital mortality. Secondary outcomes were complications and length of stay. Results Among 153 patients (79.7% male; mean age, 32.7 ± 15.9 years) who sustained axillosubclavian arterial injuries, 18 (11.8%) underwent ER and 135 (88.2%) had OR. Matched cases (ER, n = 18) and controls (OR, n = 54) had similar demographic and clinical data, such as age, gender, admission systolic blood pressure and Glasgow Coma Scale score, body Abbreviated Injury Scale scores, Injury Severity Score, and transfusion requirements. Patients undergoing ER had significantly lower in-hospital mortality compared with patients undergoing OR (5.6% vs 27.8%; P =.040; odds ratio, 0.7; 95% confidence interval, 0.6-0.9). Similarly, patients undergoing ER had substantially lower rates of surgical site infections and a trend toward lower rates of sepsis. Outpatient follow-up was available in 88.2% (n = 15) of the patients at a median time of 8 months (1-30 months). Two ER patients required open reintervention for stent-related complications (one for a type Ia endoleak and another for stent thrombosis). Conclusions In our experience with axillosubclavian arterial injuries, ER was associated with improved mortality and lower complication rates. Patient follow-up demonstrates an acceptable reintervention rate after ER. Further multicenter prospective evaluation is warranted to determine long-term outcomes.
