We describe the case of an 83-year-old woman who underwent surgical repair for abdominal aortic aneurysm with horseshoe kidney. Preoperative computed tomography（CT）scans showed the presence of not only the principal bilateral renal arteries but 2 accessory renal arteries originating from the right common iliac artery. The left accessory renal artery had 2 branches supplying each of the lower poles of the kidneys. We performed open surgery for artificial graft replacement by dividing the isthmus. The isthmus was formed of fibrous connective tissue therefore we dissected the isthmus sharply and sutured edges. A urinary fistula was absent. Since supply to the right renal lower pole via the left accessory artery was negligible, the artery was ligated. We performed this procedure safely and achieved a successful outcome.
