Classification of gastric varices according to afferent venous inflow—type 1 gastric varices are supplied by a single afferent gastric vein (a1, a2); type 2 gastric varices by multiple afferent gastric veins (b1, b2); and type 3 (c1, c2) are supplied by single or multiple gastric veins with co-existent gastric veins that are directly contiguous with a shunt, but without contribution toward gastric varices. IVC inferior vena cava, PV portal vein, LGV left gastric vein, SMV superior mesenteric vein, LRV left renal vein, SV splenic vein, PGV posterior gastric vein, SGV short gastric veins.
