title: Hybrid procedures for complex thoracoabdominal aortic aneurysms: early results and secondary interventions.
abstract: BACKGROUND
  Hybrid procedures for thoracoabdominal aortic aneurysms (TAAA) have been previously described as an attractive alternative to open reconstruction.
  
  
  METHODS
  Between 1999 and 2009, 16 patients with a median age of 67years underwent hybrid repair of a TAAA (Crawford type I: 3, type II: 3, type III: 1, and type IV: 9). In 94%, 3 and more severe comorbidities were present, with previous aortic surgery in 56% of the patients; elective/urgent repair was done in 10 and emergent surgery in 6 patients.
  
  
  RESULTS
  Primary technical success was 100%, with 31 vessels grafted. Elective/urgent mortality was 20% (2 of 10) and emergent mortality 50% (3 of 6). During follow-up time (median: 12 months) 2 patients died and 2 patients had to undergo secondary interventions.
  
  
  CONCLUSIONS
  In high-risk patients especially after prior aortic surgery hybrid repair of TAAA is feasible. However, due to high mortality rates especially in the emergent situation this procedure should be reserved only for decidedly selected patients.
