Origin

The right artery of the caudate lobe typically arises from the right hepatic artery (Furuta et al., 2009; Miyayama et al., 1990).

Course

The right artery of the caudate lobe courses posteriorly and medially.

Branches

The right artery of the caudate lobe gives off multiple small unnamed branches.

Supplied Structures

The right artery of the caudate lobe mainly supplies the lateral portion of the caudate lobe (Furuta et al., 2009).

Typically, the caudate lobe receives two arteries, one each from the right and left hepatic arteries (53% of cases). In 35% of individuals, this territory is supplied by the right hepatic artery branch only, or in 12% by the left hepatic artery branch (Furuta et al., 2009).

Artery

ScienceDirect image

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.
