*2.3.2.3 Type C*

The right posterior area of the liver is supplied by 5–11 sector-shaped branches of the portal vein branches that are derived from an arched main vessel (**Figure 5**). It is not possible for segments VI and VII to be resected individually with precision (but is possible for types A and B). The proportion of livers with type C is small but significant from the point of view of precision liver resections. Type C has two variations, type C-a (6.59%), wherein the right-posterior portal vein is sector-shaped and the right-anterior portal vein is similar to that of type A (P8), and type C-b (3.42%),
