Figure 4. Drawings illustrate the classification of gastric varices according to the patterns of their afferent gastric veins. Type 1 gastric varices are supplied by a single afferent gastric vein, type 2 are supplied by multiple afferent gastric veins, and type 3 are supplied by single or multiple gastric veins with coexistent gastric veins that are directly contiguous with the shunt (arrow) but do not contribute to the varices.
