title: Rupture of thoracic aorta resulting from blunt trauma.
abstract: BACKGROUND
  Traumatic rupture of thoracic aorta caused by blunt trauma has been observed more frequently in recent years. The aim of this study was to evaluate the state of the art of diagnostic methods used to identify this injury and the surgical techniques used to repair it.
  
  
  METHODS
  The study was performed in 29 patients undergoing surgery for traumatic rupture of thoracic aorta from November 1979 to July 1995.
  
  
  RESULTS
  All patients presented multiple blunt traumatic injuries. The suspicion of traumatic aortic rupture always arose when evidence of an enlarged mediastinal shadow was found on the chest X-ray, subsequently confirmed in 27 cases using aortography. During the period 1993-1995 11 patients underwent CT scan before aortography, which resulted false negative in 3 cases (27.2%). The decision to perform surgery was based on well defined priorities: abdominal injuries took priority over the aortic injury, and in stable patients with intracerebral injuries, head CT scan and neurosurgery were performed first. Eight patients died (overall mortality was 27.5%).
  
  
  CONCLUSIONS
  CT scan should not be used for the diagnosis of aortic traumatic rupture because it is a waste of time (all patients have to undergo aortography before surgery) and the false negative rate is too high.
