Blunt Aortic InjuryBlunt Aortic Injury
• 75% patients die at scene of accident
• 5% are unstable and die shortly after accident
• 25% of remainder die of other injuries
• Traditional approach to repair has been emergent open repair- Paraplegia 2-19%, Mortality 15-35%
• Current trend is appropriately timed urgent repair with an evolving endovascular role - Paraplegia 0%, Mortality 0-17%

• Comparison of open repair vs. stent for TTAT
• 1999 to 2011
• First thoracic aortic stent was October 2005
• Exclusively stent repair for last 4 years

• Stents Used- 7 TAG - 1 C-TAG- 17 Excluder Cuffs - 4 AneuRx Cuffs - 2 Talent - 9 TX2
• 36/40 immediate technical success
• 39/40technical success after re-interventions
• Complete coverage of traumatic tear with no stent migration or endoleaks at most recent follow-up

ConclusionsConclusions• Endovascular stents for BAI can be
performed safely with excellent short and mid-term results
• Time from admission to intervention of BAI is increased in the stent group with no increased mortality
• Stents for BAI are associated with decreased OR times and intraoperative blood transfusions compared to open
