case_images: (a-c) Left post-nephrectomy renal arteriovenous fistula (AVF) with the shunt diameter of 8.0 mm, combined with a giant left residual renal venous aneurysm; (d-f) complete occlusion of AVF by a 12 mm x 10 mm patent ductus arteriosus (PDA) occluder; (g, h) post-operative computed tomographic angiography (CTA) revealed disappearance of left renal AVF and rebound of left residual renal vein.. L: left orientation; white arrow: fistula; black arrow: aneurysmally dilated renal vein; gray arrow: implanted occluder.

case_images: The venous stump of the AVF was dilated to 100 mm in diameter (Figure 1(a) and (b)). On aortic angiogram, an AVF of the left renal pedicle and a giant aneurysm of the venous stump were noted (Figure 1(c)). Following confirmatory angiography, the occluder was deployed within the renal artery which completely isolated the AVF (Figure 1(d) and (f)). CTA at 3-, 6-, and 12-month follow-up confirmed complete isolation of the AVF and the stable location of the PDA occluder in the renal artery stump (Figure 1(g) and (h)).

case_images: (a-c) Left post-nephrectomy renal arteriovenous fistula (AVF) with the shunt diameter of 6.0 mm, combined with a giant left residual renal venous aneurysm; (d-f) complete occlusion of AVF by a 12 mm x 8 mm patent ductus arteriosus (PDA) occluder; (g, h) post-operative computed tomographic angiography (CTA) revealed stability of PDA occluder, disappearance of left renal AVF, and rebound of left residual renal vein.. L: left orientation; white arrow: fistula; black arrow: aneurysmally dilated renal vein; gray arrow: implanted occluder.

case_images: CTA displayed a left renal AVF (with a diameter of 6.0 mm) and a huge venous aneurysm (diameter of 70 mm) of the left renal pedicle (Figure 2(a) and (b)). The shunt was sealed completely (Figure 2(c) and (f)). Follow-up CTA at 3, 6, and 12 months verified complete isolation of the AVF and stable location of the PDA occluder within the left renal artery (Figure 2(g) and (h)).
