The patient sustained a gunshot wound to the right upper chest, injuring the right axillary artery and leading to upper extremity ischemia. The supraclavicular incision (cephalad to the retractors) was used to obtain proximal control of the subclavian artery. The infraclavicular incision (with retractors) exposed the area of injury, after which the axillary artery was debrided and the axilloaxillary graft was placed to restore flow.
