Renal arteriovenous fistulae (AVF) are a rare condition that can be acquired, congenital, or idiopathic. Idiopathic AVF are the rarest type of renal AVF. Traditionally, renal AVF were treated with surgery, but the mainstay of treatment has shifted to an endovascular approach by coil embolization. Embolization procedures are often difficult secondary to the "high flow" of the AVF, and there is the substantial risk of distal embolization of coils. We present a case in which an idiopathic renal AVF was successfully embolized with an Amplatzer vascular plug.
