Embolization therapy for the renal AVF. a Pre-therapeutic, b early treatment phase, and c post-therapeutic digital subtraction angiography images. The renal AVF (circled with a solid line) was filled with microcoils (circled with a dashed line) over time. The enlarged left renal vein (indicated by arrowheads) was delineated despite the arterial phase until the early therapeutic period (a, b), but disappeared after the AVF was blocked out (c), indicating a large amount of shunt flow
