Abstract
BackgroundThe 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 presentationA 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.ConclusionsBased on present results, embolization of a high-output IRAVF with an ASDO via venous access might be an efficient and safe method.
Highlights
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
For large high-output renal arteriovenous fistulas (AVFs), there is a risk of emboli shifting to unexpected areas; these are recommended for surgical treatment [5, 6]
Our patient had a high-output and extremely large fistula; the purpose of retaining sufficient blood supply of the normal renal artery could hardly be reached if the fistula was occluded via arterial access
Summary
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. Interventional embolization has become the first choice for the treatment of AVFs. A prevailing embolization method is to use gelatin sponges and elastic coils to embolize fistulas through renal arterial access. A patient diagnosed with high-output IRAVF underwent embolization with an atrial septal defect occluder (ASDO) via renal venous access, achieving a satisfactory curative effect.
