Origin

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

Course

The segment II artery passes straight to the left corner of the liver, superior to the segmental III 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 II artery supplies segment II of the liver.
