Two patients with aneurysm secondary to blunt traumatic subadventitial rupture of the distal innominate artery (IA) are reported. IA rupture was identified because of a cervical bruit in one patient and detected during thoracic aortography in the other patient. The patients had associated cardiovascular lesions consisting of traumatic aneurysm of the subclavian artery and rupture of the aortic valve, respectively. Both lesions were surgically repaired by resection of the lacerated intima and direct closure of the adventitia. In the patient who underwent repair of the aortic valve with simultaneous cardiopulmonary bypass the IA was approached after cannulation of the right common carotid artery. In the other patient the IA was repaired without use of a shunt under close EEG monitoring. Injury to the IA is rare because the artery is short and relatively well protected by the bony cage. Other cardiovascular lesions may be associated with IA rupture and a routine search should be made.
