According to Terminologia Anatomica, the portal hepatic vein (PHV) trunk bifurcates into the right branch and the left branch in the vicinity of the hepatic hillum. The caudate branches start from the transverse portion of the left branch. We studied the branching modalities of the PHV trunk and the morphological aspect of its branches at hillum level on 100 hepatic corrosion casts. Besides the homologated type (modal type, present in 97% cases), we found major branching variants of the PHV trunk in 3% cases. These variations are represented by: branching of the PHV trunk into the left branch and the posterior branch (1%), the anterior branch and the posterior branch (1%), and trifurcation into the left branch, the anterior branch and the posterior branch (1%). In case of bifurcation into a left branch and a posterior branch, the anterior branch of the PHV originates into the transverse portion of the left branch. In case of bifurcation into an anterior branch and a posterior branch, the left branch originates from the initial part of the anterior branch. In case of trifurcation into a left branch, an anterior branch and a posterior branch, the right branch is absent as a morphologic entity. These major morphological variations of branching of the PHV trunk are due to a vascular gliding phenomenon. Knowing these morphological aspects will facilitate the evaluation of the origin of caudate branches of the portal hepatic vein. (Supported by CNMP 4.1‐092/2007)
