Traumatic avulsion of the suprascapular artery.

Trauma to the subclavian artery and its branches is rare, and usually the result of penetrating injuries. Blunt trauma presents its own peculiar management difficulties, particularly when causing haemorrhage into the thoracic cavity. Cardiothoracic surgeons may be asked to deal with such cases, so an understanding of the anatomy and options for surgical access are essential. We present a case of blunt avulsion of the suprascapular artery resulting in massive haemothorax, a previously unreported injury.
