Figure 9a. Type B-3 gastric varices. (a) Contrast-enhanced CT scan shows gastric varices. (b) Balloon-occluded venogram of the gastrorenal shunt shows only the collateral draining veins. (c) Fluoroscopic image obtained after coil embolization of these collateral vessels (arrows indicate coils) demonstrates the drainage route of the varices. The image shows that EOI injected via the microcatheter fills the varices well. (d) Contrast-enhanced CT scan obtained 2 weeks later shows complete thrombosis of the varices.
