Terminologia Anatomica (1998) homologates 2 arteries of the caudate lobe (CLA): right (RCLA) and left (LCLA), each originating from the homonym branch of the proper hepatic artery (PHA) (right branch ‐ RBr; left branch ‐ LBr). Our previous work evidenced variability both in origin and in number of CLA. We analyzed on 150 corrosion casts the types of spatial distribution of CLA according to their origin in different branching portions of PHA. The corrosion casts were made by injecting with plastic (AGO II paste and TECHNOVIT 7143) of the vasculo‐ductal systems, followed by parenchyma corrosion with hydrochloric acid. We analyzed at first the branching modalities of the PHA trunk and found 3 distinct aspects: Type I (modal, 74.67%) forking of PHA into right branch (RBr) and left branch (LBr); Type II (20.67%) forking of PHA into RBr and lateral branch (LBr); Type III (4.67%) forking of PHA in LBr and posterior branch (PBr). RBr is the origin of CLA in 33.67% cases, and LBr in 54.04%. We found origins of CLA from the anterior branch (1.05%), the posterior branch (1.40%), the lateral branch (2.81%) and the medial branch (7.02%). We found a higher frequency of origin of CLA from the medial branch in cases when it originates from the RBr. Evidence of CLA origin from other elements of the branching system of PHA than RBr and LBr is useful when planning and performing caudate lobe parenchyma surgery (Supported by CNMP 41092/2007).
