Deskripsi
Renal arteriovenous fistulas (AVFs) are rare vascular abnormalities. Their high-flow nature may result in increased cardiac output and lead to heart failure. Transcatheter endovascular management of renal AVFs with various embolization materials has been the treatment of choice in recent years. Embolization of large renal AVFs poses a risk of embolization through the AVF to the pulmonary circulation. Herein, we present the case of a patient whose large high-flow renal AVF was treated by a novel method involving the use of a bare stent and detachable metallic coils—called a wire-trapping technique—as well as compare this method with vascular plugs. Keywords: Transcatheter embolization, Arteriovenous fistula, Across-stent wire trapping
