Background: Traumatic injuries to peripheral arterial vessels are increasingly managed with endovascular techniques. Early small series have suggested that endovascular therapy is feasible and decreases operative blood loss, but these data are limited. The purpose of this study was to evaluate the feasibility and outcomes of endovascular management of nonaortic arterial trauma.
Materials and methods: We reviewed records of traumatic nonaortic arterial injuries presenting at an urban level 1 trauma center from December 2009-July 2013. Patients undergoing treatment in interventional radiology and patients whose injuries occurred >72 h before presentation were excluded. Demographics, indicators of injury severity, operative blood loss, transfusion requirements, and clinical outcome were compared between patients undergoing endovascular and open management using appropriate inferential statistics.
Results: During the study period, 17 patients underwent endovascular interventions and 20 had open surgery. There were 19 upper extremity and/or thoracic outlet arterial injuries, 15 lower extremity injuries and 11 pelvic injuries. Endovascular cases were completed using a vascular imaging C-arm in a standard operating room. Estimated blood loss during the primary procedure was significantly lower with endovascular management (150 versus 825 cc, P < 0.001). No differences were observed between cohorts in age, injury severity score, intensive care unit length of stay, arterial pH, transfusion requirements, inpatient complication rate, or mortality.
Conclusions: Our experience with endovascular management demonstrates its feasibility with commonly available tools. Operative blood loss may be significantly decreased using endovascular techniques. Further study is needed to refine patient selection criteria and to define long-term outcomes.
