Abstract:
The elements of afferent pedicle of the liver have a segmental distribution to the liver parenchyma. Divergence part of the hepatic portal vein is the main element of intraparenchymatous spatial distribution vasculo-ductal systems. On 500 divergence (intraparenchimal) portions of of hepatic portal vein (125 pieces of liver corrosion casts, 125 ultrasound images, 125 images of MDCT angiography and 125 images of MR angiography), it was highlighted a number of six morphological types of intraparenchymatous part of hepatic portal vein, which are presented as follows. Symmetric bifurcation (standard portal vein anatomy) (Type I - 76.2%) in which the main portal vein trunk divides into right and left portal branches. Trifurcation, (Type II - 10.4%) in: the left branch, the (right) anterior branch, and the (right) posterior branch. Quadrifurcation, (Type III - 0.2%) in: anterior and posterior branches in the right part, and lateral and medial branches in the left part. Asymmetric bifurcation, (Type IV - 7.4%) in which the (right) posterior branch is the first branch of the main portal vein trunk Asymmetric bifurcation of the right branch, (Type V - 4.4%) in which the branch for segment V or VIII (anterior branch) is the first branch of the right branch. Asymmetric bifurcation of the right branch, (Type VI - 1.4%) in which the branch for segment VI or VII (posterior branch) is the first branch of the right branch. Knowledge of these aspects is important both to investigate morphological imaging, and in performing partial resection and liver transplantation. Keywords: hepatic portal vein branches; morphological types; corrosion casts; ultrasound images; MDCT angiography; MR angiography; clinical and surgical inplications
