A fenestrated covered suprarenal aortic stent.
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.
