          Abstract

          Blunt traumatic innominate artery injuries occur in polytrauma victims who have suffered high-speed motor vehicle collisions. Their associated injuries may preclude the use of heparin and affect surgical management and perioperative neurological risk. The uniqueness of this case is combining the arterial injury repair with a severe progressive neurological injury that prohibited standard perioperative antiplatelet or anticoagulent use.

          Rupture of the innominate artery from blunt trauma: current options for management.

          Rupture of the innominate artery is the second most common intrathoracic arterial injury from blunt trauma. It is frequently accompanied by major trauma to other organs. The traditional management is expeditious surgical repair. Three patients presented to the Emergency Department after motor vehicle collisions with traumatic rupture of the innominate artery from 2001 to 2003. One patient presented with an isolated innominate artery injury. The other two patients presented with multi-system trauma. All patients underwent surgical repair; however, repair was individualized in each case. Diagnosis was obtained via arteriography in all patients after the admission chest radiographs suggested mediastinal injury. In the patient with isolated traumatic innominate artery rupture, urgent repair was performed. In the remaining two, the repair was intentionally delayed (hospital day 4 and 19) until they stabilized or recovered from other injuries or complications. In one of these patients, repair was delayed after an endovascular repair failed. In both patients who underwent delayed repair, mean arterial pressure was maintained at <70 mmHg with beta-blockade. All patients underwent repair without cardiopulmonary bypass and were monitored for adequate cerebral perfusion pressures by measuring the right carotid artery stump pressure. Successful repair was achieved in all the three patients without postoperative complications or mortality. Rupture of the innominate artery from blunt trauma is an infrequent but life-threatening injury that mandates repair. In patients with isolated injuries, prompt intervention is warranted. However, intentional delayed repair may be a practical alternative for those patients with multi-system trauma.

            Traumatic rupture of the innominate artery.

            Blunt traumatic rupture of the innominate artery is uncommon. We reviewed our experience to correlate the impact of patient stability, presence of associated injuries and location of the injury within the artery with outcome. A retrospective review was performed of patients admitted between January 1, 1998 and December 17, 2002 with traumatic innominate artery rupture. Injuries were defined as proximal if they were

              Blunt injury of the innominate artery: a case report and review of literature.

              Innominate artery injury after blunt trauma is uncommon and mostly observed at its origin from the aorta. We report here an unusual case of distal innominate artery injury associated with acute right subclavian occlusion. MEDLINE search of blunt traumatic injury to the innominate artery revealed a total of 132 case reports by the end of 2003, including this case report, and all these published studies were reviewed.
