Segment III Artery

Origin

The segment III artery arises from the lateral segmental artery of liver.

Course

The segment III artery passes inferiorly and to the left. This course takes it in the same direction, but inferior to the segment II artery.

The pattern of segmental artery origins and courses is extremely variable. Most of the research is based on contrast proper hepatic artery arteriography (Furuta et al., 2009; Favelier et al., 2015). The account given is the most common but was found in only 27% of cases in a cadaveric study of 100 livers (Garg et al., 2019).

Branches

There are no named branches.

Supplied Structures

The segment III artery supplies segment III of the liver.
