title: Percutaneous embolization of idiopathic renal arteriovenous fistula using Amplatzer vascular plug II.
abstract: Renal arteriovenous fistula (AVF) presents a rare but important condition that can be acquired, congenital, or idiopathic. Embolization techniques have recently been considered the first-line therapy in the treatment of these lesions, but they carry a possible high risk of distal migration of embolic agents into the venous and pulmonary circulation. This risk is especially important with large, high-flow fistulas. In this report, we present a case in which a 31-year-old man with a symptomatic idiopathic AVF was treated with embolization using the Amplatzer vascular plug II after unsuccessful superselective embolization using coils. This method allowed for complete occlusion of the high-flow fistula with good preservation of arterial supply to the renal parenchyma.
