Renal artery aneurysm (RAA) concomitant with a renal arteriovenous fistula (RAVF) has been infrequently reported in the literature. We report a case of a 42-year-old man suffering from a giant RAA combined with a congenital high-flow RAVF. The contrast-enhanced CTA showed a 12.7-cm RAA synchronous with an RAVF between the right renal artery and a draining vein. After a comprehensive preoperative assessment, an endovascular approach was decided. Successful embolization was performed using an Amplatzer vascular Plug, and multiple coils. Completion angiogram demonstrated no flow into the RAA. The results of longterm follow-up demonstrate that endovascular techniques are safe and effective for the management of RAAs combined with high-flow RAVF.
