Fig. 3

Close-up pictures of the ascending colonic varix. a Contrast medium-enhanced CT before B-RTO shows the ascending colonic varix (black arrowhead), the main draining vein (black arrow), and the ileocolic vein (white arrows) as a feeder vein. b B-RTV from the main draining vein (black arrow) shows the ascending colonic varix (black arrowhead) and microballoon catheter (gray arrowhead). c After injection of the sclerosing agent, microcoils (white arrowhead) are inserted via the microballoon catheter (gray arrowhead). When the balloon is deflated, contrast medium is retained in the colonic varix (black arrowhead) and the draining vein (black arrow). c corresponds to the enlarged image of Fig. 2b. d The day after B-RTO, contrast medium-enhanced CT shows no enhancement of the draining vein (black arrow), the colonic varix (black arrowhead), and the ileocolic vein (white arrow)
