Endovascular repair of aortic aneurysms in the the presence of a horseshoe kidney.

PURPOSE

To report two cases of endovascular aortic aneurysm exclusion in patients with a horseshoe kidney.

METHODS AND RESULTS

Two male patients, one with a known horseshoe kidney and history of multiple previous laparotomies, presented with abdominal aortic aneurysms of approximately 6-cm diameter. Each was treated with a tapered aortomonoiliac polytetrafluoroethylene graft secured proximally with a Palmaz balloon-expandable stent. The endograft was sutured distally to a Dacron femorofemoral crossover graft. An anomalous renal vessel was sacrificed in one case. The aneurysms were successfully excluded, and the patients recovered without sequelae.

CONCLUSIONS

Endovascular repair should be considered as a treatment option in patients with aortic aneurysm in the presence of a horseshoe kidney, particularly if the renal vasculature can be wholly preserved.
