  • Apr 2015
The aim of the present study was to investigate the effects and safety of a patent ductus arteriosus occluder (PDAO) in the management of major abdominal arteriovenous fistula. A 56-year-old man was admitted into our hospital, presenting with impeded defecation and claudication. Computed tomographic angiography (CTA) was conducted upon admission, w...

  • May 2024
Background/Objectives: Retrograde access of the peroneal artery (PA) is considered technically challenging and at risk of bleeding. The aim of this multicentre retrospective study was to assess the safety, feasibility, and technical success of this access route for infrainguinal endovascular recanalizations. Methods: We retrospectively analyzed 186...

Endovascular Therapy of a Giant Renal Artery Aneurysm Combined With High-Flow Renal Arteriovenous Fistula Using a Patent Ductus Arteriosus Occluder

Renal artery aneurysm (RAA) concomitant with a renal arteriovenous fistula (RAVF) is extremely rare. A 32-year-old man suffered from a giant RAA combined with high-flow RAVF. The computer tomographic angiography (CTA) demonstrated a RAA, which is 6.3 cm in length and 2.1 cm in diameter, combined with an arteriovenous fistula between the right renal artery and right renal vein (fistula area:1.05 cm × 1.0 cm). After a comprehensive preoperative assessment, a patent ductus arteriosus occluder (PDAO) was implanted. At a 1-year follow-up, the CTA study showed that the PDAO was in situ and there was no recanalization of the lesion. At a third-year follow-up, ultrasound examination showed an image of right renal atrophy. The results of long-term follow-up demonstrate that PDAO is safe and effective for the management of RAAs combined with high-flow RAVF.
