ABSTRACT: Arteriovenous fistula is a high-flow vascular malformation characterized by a direct connection between an artery and a vein without the presence of a nidus (a network of arterial and venous channels). Renal artery aneurysm concomitant with a renal arteriovenous fistula (RAVF) is extremely rare. We report the case of a 45-year-old woman with a giant renal artery aneurysm combined with RAVF who presented with gross hematuria. The patient was successfully treated by embolization of a giant extrarenal aneurism and RAVF using coils and a plug device. RAVF can lead to harmful complications, and treatment is necessary upon diagnosis. Endovascular embolization is a feasible, efficient, and safe method able to retain maximal normal renal function
