[Anatomic and surgical aspects of intrahepatic segmentation].

This article presents anatomical and surgical patterns of hepatovenous and portal segmentation in the human liver. Special attention was drawn to the significance of portal fissures, their projections and surgical approach to large blood vessels. The anatomical variations of hepatic veins and the constituents of the portal triad (with particular surgical importance) were also included. Finally, the study gives a brief description of the perivascular fibrous capsule morphology and its relations to the portal bifurcation.
