title: A fenestrated covered suprarenal aortic stent.
abstract: OBJECTIVE
  to address the clinical problem of inadequate neck length of abdominal aortic aneurysms in endoluminal surgery.
  
  
  METHODS
  a covered suprarenal aortic stent was designed with a fenestration to preserve blood flow in a targeted renal artery.
  
  
  METHODS
  a Dacron-covered stent was accurately cut to size with a fenestration according to pre-imaging studies.
  
  
  RESULTS
  the stent was successfully deployed in canine models, preserving the visceral and renal artery of interest.
  
  
  CONCLUSIONS
  by accurately placing a covered stent in the aorta and preserving the blood flow to its branches, it may be possible to extend the indications for endoluminal aortic aneurysm grafting.
