Transcatheter arterial embolization of aneurysmal-type renal arteriovenous fistula: a case report

We report a case of aneurysmal-type renal arteriovenous fistula, which was successfully treated with transcatheter arterial embolization (TAE). A 73-year-old woman was referred to our hospital because of an incidental abnormal renal mass detected by computed tomography (CT). CT scan showed a round mass (4 x 3 x 3 cm) in the right kidney. Magnetic resonance (MR)-angiography and angiography revealed an aneurysmal type renal arteriovenous fistula (AVF). The patient was treated with TAE using detachable coils. CT, MR-angiography and angiography are useful means for the diagnosis of renal arteriovenous fistula. TAE is a powerful treatment for renal arteriovenous fistula.
