title: Endovascular Surgery for Traumatic Thoracic Aortic Injury: Our Experience with Five Cases, Two of Whom were Young Patients.
abstract: OBJECTIVE
  We present our experience of endovascular surgery for traumatic aortic injury and the results of our procedures.
  
  
  METHODS
  From January 2009 to December 2013, we performed endovascular repairs of traumatic thoracic aortic injury on 5 male patients 16-75 years old (mean, 50.8), two of whom were young. Three of the patients had multiple organ injuries. The mean interval time to the operation is 22.0 hours (range, 10-36). All patients underwent endovascular repair with heparinization. The isthmus regions were seen in three cases and all of them were needed left subclavian artery (LSA) coverage. In the two young patients, the deployed stent graft was 22 mm (22.2% oversizing for diameter of aorta) and 26 mm (36.8% oversizing), respectively.
  
  
  RESULTS
  The procedures were successful in all patients, with no early mortality, paraplegia or stroke. During 3-63 months (mean, 30.8) follow-up period, no one experienced stent graft-related complications. One patient with LSA coverage experienced arm ischemia but the symptom improved with time.
  
  
  CONCLUSIONS
  Endovascular surgery for traumatic thoracic aortic injury can be performed safely with low mortality or morbidity even in young small aorta. Accumulation of clinical experience and evaluation of long-term outcomes are necessary.
