title: Twenty consecutive cases of endograft repair of traumatic aortic disruption: lessons learned.
abstract: OBJECTIVE
  Endograft repair holds considerable promise in the treatment of traumatic disruption of the thoracic aorta because patients often have multiple coexisting injuries further complicating traditional open repair. In addition, patients are often young, with an aortic anatomy dissimilar to those with atherosclerotic aneurysms. As a result, techniques for endograft repair have to be refined accordingly.
  
  
  METHODS
  The records of 20 consecutive cases of traumatic aortic disruption treated by endograft repair at a single institution were reviewed.
  
  
  RESULTS
  Mean patient age was 40 years (range, 17 to 88 years), and 17 (85%) of 20 patients were men. All cases were completed. There were no procedure related deaths, but four (20%) patients died of their co-injuries. Only two (10%) of 20 required a graft >28 mm in diameter, and nine (45%) aortas were small enough to require use of 23-mm abdominal cuffs. Six (30%) of 20 cases required complete or partial coverage of the left subclavian artery. Placement of a proximal extension was required in one patient for a type I endoleak. A graft collapse occurred in one patient that required surgical removal and aortic repair.
  
  
  CONCLUSIONS
  Endovascular repair of traumatic aortic disruption can be accomplished in most cases. Compared with atherosclerotic aneurysms, the proximal thoracic aorta tends to be smaller and the arch angle tighter in an aorta 19mm in diameter. This frequently necessitates the use of smaller devices and less stiff wires. Surgeons should be prepared to cover the left subclavian artery if needed, have a wide range of device sizes in stock to avoid over-sizing, and show restraint if the anatomy appears unsuitable.
