Pseudoaneurysm of the subclavian artery is a rare complication of clavicle fracture. The consequences of pseudoaneurysm of the subclavian artery usually consist of brachial plexus injury, vessel compression, neurological events and life-threatening rupture. We present a 54-year-old woman with a chief complaint of progressive drooping of the left eyelid. Subclavian artery pseudoaneurysm caused by traumatic clavicle fracture was finally diagnosed. She was treated successfully by implantation of a stent and showed gradual improvement of blepharoptosis.
