Objective: To report our experience with surgery of thoracic aortic rupture due to blunt trauma. Methods: Between October 1976 and October 1999, 50 patients suffering from acute rupture of the thoracic aorta due to blunt trauma were operated on. On admission, 22 patients (44%) presented with hypovolemic shock and all but five (90%) sustained major associated injuries. Thirty-one patients (62%) underwent immediate operation for aortic repair, whereas the procedure was delayed from 6 to 60 days in ten patients because of late diagnosis or coexisting life-threatening lesions thought to largely worsen the operative risk. In 48 patients, the aortic repair was carried out with the aid of cardiopulmonary bypass (CPB) in order to maintain the distal perfusion and to prevent spinal cord injury. An inert ‘Gott’ shunt and the ‘clamp-and-sew’ technique were used in one patient each. Results: The hospital mortality amounts to 18% (nine patients). Four patients (8%) died intraoperatively and five patients (10%) died in the postoperative course. In five patients (10%) death was caused by cerebral or pulmonary hemorrhage, possibly worsened by systemic heparinization during CPB. One case of postoperative paraplegia (2%) was observed in a patient operated on with the aid of CPB. There was neither aortic rupture nor sudden death in the group of patients in whom the surgical procedure was delayed. Conclusions: The immediate outcome of patients suffering from acute traumatic aortic rupture strongly depends on the associated injuries. In some cases, the emergency aortic repair must be favorably delayed because of the necessity of life-sustaining measures and management of major coexisting injuries, which could be worsened by the use of CPB. Conversely, the risk of paraplegia is significantly reduced by the use of CPB and distal perfusion during the time of aortic cross-clamping.
