Figure 1b. Drawings illustrate additional techniques for treatment of type 2 gastric varices. (a) Subselective injection of EOI via a microcatheter. The microcatheter is navigated through a balloon catheter into the nonopacified portion of the varices. EOI injected via the microcatheter will fill the entire variceal complex. (b) Coil embolization of afferent gastric veins, which prevents insufficient variceal filling and unexpected flow of EOI into the portal vein. The coil is placed in the gastric vein via a catheter that is introduced by means of portal venous access (PTO) or transileocolic venous access (TIO) at minilaparotomy.
