title: Conventional surgical repair of traumatic rupture of the thoracic aorta.
abstract: OBJECTIVE
  Traumatic rupture of the thoracic aorta is a life-threatening injury requiring urgent surgical intervention. Despite recent improvements in resuscitation and emergency operative techniques, the outcomes of patients with multiple injuries are still associated with a high mortality rate. We retrospectively examined the preoperative demographic data, associated complications and mortality rate of these patients.
  
  
  METHODS
  We analyzed the data (1991-2009) of 18 patients with acute traumatic rupture of the thoracic aorta. Most patients had rupture limited to the aortic isthmus and severe associated injuries in other organs. The aorta was repaired by direct suturing, patch plasty (n = 5; 27.7 %) or graft interposition (n = 9; 50 %).
  
  
  RESULTS
  The overall mortality rate was 33.3 %. All six patients who underwent emergency surgery within 2 h died, four intra-operatively and two postoperatively. The causes of the intra-operative mortality were uncontrollable hemorrhage and irreversible cardiac arrest due to penetrating injury of the thoracic aorta and intercostal arteries in three patients, and uncontrollable hemorrhage due to severe liver laceration in one. The surgical complications (42.8 %) were acute lung injury (n = 2), liver insufficiency (n = 2), acute renal failure (n = 1) and cerebral infarction (n = 1). No patients had postsurgical paraplegia. The mean period between arrival and treatment and the mean Injury Severity Score were significantly higher in group D than in group A.
  
  
  CONCLUSIONS
  To improve the outcome of traumatic thoracic aortic injury, the degree of multi-organ damage, the priority of treatment be evaluated accurately is important.
