Traumatic injuries to the subclavian vessels are relatively uncommon and surgical repair may be technically challenging. With the increasing availability of endovascular techniques for nontraumatic arterial disease, an increase in the use of stenting for traumatic vascular injuries can be expected. This report describes the fifth successful endovascular repair with stenting of a pseudoaneurysm of the subclavian artery as a result of blunt trauma, and the first American report of such repair used in the acute or immediate management of blunt subclavian artery injury.
