Juxtarenal aortic aneurysm associated with a horseshoe kidney. Transfemoral endoluminal repair.

Horseshoe kidney complicates aortic aneurysm surgery in 1 of 200 cases. A patient with asymptomatic juxtarenal aortic aneurysm associated with a horseshoe kidney was successfully treated by stent graft placement. The kidney was supplied by 4 renal arteries. The proximal uncovered part of the stent graft was anchored across the origin of 1 renal artery. Another renal artery, arising from the aneurysmal sac, was occluded by the covered part of the stent graft. A kidney infarction developed postoperatively, which did not affect renal function or blood pressure. The patient was discharged from the hospital in good condition. Follow-up computed tomography and angiography confirmed a satisfactory result of the endovascular treatment.
