We report the case of a 65-year-old man who presented with an infraren
al aortic aneurysm in association with a congenital right pelvic kidne
y vascularized by 2 aortic arteries, I of which arose from the aneurys
mal aorta and the other from the common right iliac artery. Successful
surgery consisted of excising the aneurysmal aortic segment and repla
cing it with a Dacron tube graft, then implanting the upper renal arte
ry (supplemented by a short segment of saphenous venous graft) in She
Dacron prosthesis. We review 6 other cases of this rare pathologic ass
ociation, found in our search of the literature, and discuss technique
s of renal protection and (when necessary) reimplantation of the anoma
lous arteries.
