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.
