Figure 1 Schematic illustrates Couinaud segmental liver anatomy and the normal portal venous structures. The possible hepatic resection procedures are also shown.

Figure 2 (A,B) Schematics illustrate the normal portal vein (PV) branches from anterior (A) and inferior (B) perspectives. hp, horizontal part; LPV, left portal vein; RPV, right portal vein; up, umbilical (vertical) part.

Figure 3 Schematics illustrate selected variants of the portal venous system. (A) Bifurcation of the right posterior sectoral branch from the left main portal branch, with the right anterior sectoral branch arising from the left main portal branch; (B) portal trifurcation; (C) portal quadrifurcation; (D) bifurcation of the right portal vein (RPV) into anterior (Ant.) and posterior (Post.) branches, which supply segments V/VIII and VI/VII, respectively; (E) complete absence of the RPV. All hepatic segments are supplied by the LPV. hp, horizontal part; LPV, left portal vein; PV, portal vein; up, umbilical (vertical) part.
