Abstract
Objective: to address the clinical problem of inadequate neck length of abdominal aortic aneurysms in endoluminal surgery.
Design: a covered suprarenal aortic stent was designed with a fenestration to preserve blood flow in a targeted renal artery.
Method and material: 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.
Conclusion: 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.
