We have experienced two cases of traumatic subclavian artery rupture at the department of thoracic and cardiovascular surgery, Youngdong Severance hospital, Yonsei University college of medicine. One was combined with brachial plexus injury and the other was combined with brachial plexus injury and subclavian vein rupture. They were treated with graft interposition after segmental resection of ruptured subclavian artery and neurorrhaphy for brachial plexus injury. Post operative courses were not eventful.
