title: Immediate endovascular treatment of blunt aortic injury: our therapeutic strategy.
abstract: BACKGROUND
  Posttraumatic aortic rupture is a potentially lethal injury. Endovascular procedure has recently proved to be a valid option. Timing of the treatment, however, is still a debated issue. We evaluated the feasibility and safety of immediate stent-graft repair of acute posttraumatic aortic injury.
  
  
  METHODS
  From 1998 to 2005, 15 patients (11 men and 4 women, mean age 42.3 years) with blunt aortic injury were treated with immediate stent-graft positioning. In patients with clinical and radiologic signs of impending rupture, endovascular treatment was performed in an emergency setting (11 cases). In the 4 remaining patients the aortic lesion was treated after clinical management. When present, immediate life-threatening nonaortic lesions were treated before endovascular stenting (6 cases). In 1 case emergency laparotomy and endovascular procedure were performed simultaneously. Stent positioning was monitored by intraoperative transesophageal echocardiography in all cases.
  
  
  RESULTS
  Endovascular procedure was successful in 100% of the patients. Two patients died perioperatively as a consequence of a multiorgan failure. Both patients were in American Society of Anesthetists class V and were in severe intractable hemorrhagic shock before the procedure. Computed tomography scan performed before discharge showed correct positioning of the stent graft and absence of endoleaks in all cases. At a mean follow-up of 29 months (range 1-79) all patients were alive but 1, who died of unrelated cause, and no intervention-related complication had occurred.
  
  
  CONCLUSIONS
  Immediate stent-graft repair of posttraumatic aortic injury is a feasible and safe procedure. It allows us to minimize the surgical risks and to treat stable and unstable lesions even when associated lesions would contraindicate traditional surgical intervention.
