ABSTRACT
Aortic stent grafting may be an alternative to surgery for patients with an abdominal aortic aneurysm and coexistent horseshoe kidney but is not without difficulties. This study examines the renal consequences of aortic stent grafting in such patients. This is a retrospective review of patients with horseshoe kidney in whom aortic stent grafting was performed between December 1995 and August 2000. Follow-up occurred within the EUROSTAR protocol and included measurement of serum creatinine. Of 130 patients in whom aortic stent grafting was performed, 4 had coexistent horseshoe kidney. In all patients the aneurysm was successfully excluded with the occlusion of between one and four anomalous renal arteries. At follow-up, no clinically significant renal impairment was detected. Endovascular aneurysm repair is an attractive option for patients with a horseshoe kidney and normal preoperative creatinine levels.
