Delayed treatment of a traumatic left subclavian artery pseudoaneurysm.
A 22-year-old man sustained 4 gunshot wounds to the upper torso resulting in left pneumothorax, an expanding right neck hematoma, left humerus fracture, a traumatic arteriovenous fistula from the right subclavian artery to the right brachiocephalic vein, and pseudoaneurysm formation from partial transection of the right subclavian artery. The patient underwent emergent repair of the confluence of the right internal jugular, subclavian and brachiocephalic veins, and laparotomy secondary to compartment syndrome. Seven weeks later, with the pseudoaneurysm enlarged to 6 cm, it was repaired with combined access via the right common femoral artery and right brachial artery. The pseudoaneurysm was covered with a 7 mm x 8 cm fluency-covered stent graft and postdilated with a 7 mm x 4 cm balloon. Postoperatively, the patient had palpable pulses, occlusion of the pseudoaneurysm, and excellent blood flow into the arm.
