Tracheoinnominate artery fistula caused by migration of a Kirschner wire.

Iatrogenic injury is an underreported but potentially devastating complication of orthopedic wire migration. We report a 48-year-old man with a tracheoinnominate artery fistula caused by migration of a Kirschner wire that was inserted for fixation of a left clavicle fracture nine years before. Following surgical removal of the wire and repair of both trachea and innominate artery, the patient recovered eventually. Although migration of orthopedic wire to the trachea has been reported twice in previous literature, such a complication involving both the trachea and arch vessel was not previously described. Physicians who care for patients with orthopedic wires in place should be aware of migration with tracheoinnominate artery fistula and other iatrogenic injuries as potentially lethal complications.
