The anterior segmental artery of the liver arises from the right hepatic artery.


Typically, the right hepatic artery within the parenchyma of the right functional lobe of the liver quickly gives a side branch, then bifurcates into two terminal branches, one of which is the anterior segmental artery of the liver. It passes relatively straight, superior and to the right (Furuta et al., 2009).


The anterior segmental artery gives several segmental branches variably to Segment 1 (caudate lobe) and provides terminal branches to Segments V and VIII (Favelier et al., 2015).

Note that from the common hepatic artery to the terminal branches, the vasculature of the hepatobiliary system is extremely variable. What is given here is the most common arrangement. However, any surgeon operating in this area must first establish the branching pattern either radiographically or by exploration before ligating any vessel in this region.

Supplied Structures

The anterior segmental artery provides arterial supply to segment I (caudate lobe), segment V, and segment VIII of the liver (Favelier et al., 2015).

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
