Delayed union of a fracture of the middle third of the clavicle presenting with a late subclavian pseudoaneurysm.
This is the case of a 46-year-old man who presented 3 months following a fracture of the middle third of the clavicle with an expanding mass in the supraclavicular fossa. Upon admission, a pulsatile mass was identified and X-rays showed delayed union of the fracture. Seven days after admission, skin necrosis developed. Arteriography performed 3 days later demonstrated a round subclavian pseudoaneurysm measuring 5 cm in diameter. It was occluded by means of an endovascular prosthesis. Four days after arteriography, the delayed union was treated by excision of the necrotic skin and internal fixation with a plate and screws. After 1 year of follow-up, the outcome was clinically and radiologically satisfactory.
