Abstract
Endovascular repair of abdominal aortic aneurysm (AAA) have accepted widely as a low invasive treatment, but with a potentiality of a development of endoleaks, which can be a cause of AAA rupture after the treatment. We describe endovascular repair combined with Kilt technique to treat AAA with aberrant renal arteries (ARA) of horseshoe kidney. A 79-year-old man was referred because of a 60 mm infrarenal AAA with horseshoe kidney. The horseshoe kidney had 3 ARA from AAA connecting to isthmus. His renal function was almost normal. Preoperative selective renal artery angiography with enhanced computed tomography (CT) scan showed that more than two third of the total renal mass was supplied by the original renal arteries. Endovascular repair without reconstruction of ARA was done. In this treatment, Kilt technique was performed before main body deployment, to avoid an appearance type II endoleak from ARA and inferior mesenteric artery. The postoperative enhanced CT scan showed a slight isthmus reduction, without any endoleaks. Postoperatively, the renal function showed no serious damage. Endovascular Repair combined with Kilt technique may be considered appropriate in suited AAA cases with ARA of horseshoe kidney.
