Simple elbow dislocation is one of the most common joint dislocations and has a good prognosis. Complete transection of the brachial artery rarely ensues without an associated fracture. This case report describes this rare complication and its imaging findings in a 27-year-old man suffering from such a simple elbow dislocation. The diagnosis was made by computed tomographic angiography and duplex ultrasound. The brachial artery was repaired with a saphenous vein graft and the distal circulation was restored.
