An arteriovenous fistula from a proximal renal artery bifurcation:
1. Hand injection demonstrates a proximal renal artery bifurcation and a blush at the middle third of the right kidney.
2. Super selective contrast injection demonstrates an arteriovenous fistula, arising from a branch of the accessory renal artery. Note the venous outflow earlier than the parenchymatous phase.
3. Selective right renal artery angiography post coil embolization. Note the resolution of the AV fistula without compromising the renal parenchyma.
