Purpose: To report an unusual case of endovascular abdominal aortic aneurys
m (AAA) exclusion in which a fenestrated stent-graft was used to seal a pro
ximal Type I endoleak.
Methods and Results: An 84-year-old man with a 6.0-cm AAA underwent an aort
omonoiliac aneurysm exclusion procedure that was complicated by a proximal
endoleak. Because the patient had no right kidney, an additional stent-graf
t was designed to cover the right renal artery stump while preserving left
renal perfusion through a fenestration in the graft material. This approach
was successful in obliterating the endoleak around the proximal attachment
site, but flow through the lumbar arteries remained.
Conclusions: The use of a fenestrated stent-graft is feasible, but the type
of fenestration in this case has limited applicability owing to the rarity
of patients with suitable anatomy.
