Early diagnosis and treatment of a posttraumatic pseudoaneurysm/dissection of the innominate artery.

A 25-year-old male developed a traumatic intimo-medial dissection and saccular pseudoaneurysm at the origin of the innominate artery following a motorcycle accident. On physical examination there was no perceivable trauma to the chest. In addition, there were no clinical symptoms that suggested this serious injury. The patient was managed with successful stent-graft placement on an elective basis.
