Figure 1: Portosystemic shunt Classification. (A) Normal. (B) Type I: Morgan and Superina Classification: Intrahepatic Portal Vein absent. Liver not perfused with portal blood-total shunt. Ia: SMV and splenic vein do not joint to form confluence. Ib: SMV and splenic vein join to form confluence trunk. (C) Type II: (Lautz et al.). Liver perfused with portal blood-partial shunt: IIa: Arising from left or right portal vein to the IVC. IIb: Arising from the main portal vein (including its bifurcation or splenomesenteric confluence) to the IVC. IIc: Arising from the IMV, gastric, or splenic veins into the IVC
