Figure 9a. (a) Drawing illustrates type 3 gastric varices that are supplied by multiple gastric veins with coexistent gastric veins that are directly contiguous with the shunt but do not contribute to the varices. Arrow indicates direct shunting vein. (b) Drawing illustrates the standard BRTO method for type 3 gastric varices. EOI injected via a balloon catheter tends to flow into the direct shunting vein (arrows).
