Fig. 2. Peri-biliary arterial plexus. Super-selective digital angiography depicted a tumor stain (arrowhead; A). A microballoon catheter was deeply placed adjacent to the nodule (arrow; B) and lipiodol-balloon-occluded transarterial chemoembolization (B-TACE) was performed. Digital angiography during lipiodol infusion depicted a tumor (white arrowhead; B) and retrograde filling of lipiodol in small arteries accompanying with the tumor feeder (black arrowheads; B). But these small arteries were not depicted on the digital angiography performed via proximal portion (arrow; A). We speculated that the small arteries, peri-biliary plexus were opened to supply ischemic portion produced by B-TACE.
