Embolization of high-output idiopathic renal arteriovenous fistula primarily using an atrial septal defect occluder via venous access: a case report

BMC Nephrol. 2019 Jan 11;20(1):15. doi: 10.1186/s12882-019-1200-x.

Abstract

Background: The case report is to evaluate the efficacy and safety of embolization of a high-output idiopathic renal arteriovenous fistula (IRAVF) with an atrial septal defect occluder (ASDO) via venous access.

Case presentation: A 57-year-old male diagnosed with high-output IRAVF received embolization with an ASDO via renal venous access and compact occlusion with 3 vascular plugs and a detachable elastic coil. The IRAVF was successfully occluded. After a follow-up of 2 months, renal arterial computed tomography angiography (CTA) showed the precise location of the ASDO. No complications were observed after 2 years' follow-up.

Conclusions: Based on present results, embolization of a high-output IRAVF with an ASDO via venous access might be an efficient and safe method.
