SECTIONAL ANATOMY OF THE HEPATIC VEINS ON THE CORONAL PLANE / 解剖学报

ABSTRACT

Objective To provide sectional anatomic data for the coronal imaging diagnosis and surgical treatment of the diseases of the liver.Methods The course,distribution of left,middle,and right hepatic veins and their important tributaries as well as the relationship with the hepatic portal veins were investigated using serial coronal sections of the trunk of 30 adult cadavers,coronal MR images of abdomen of 10 adult healthy volunteers and three-dimensional MSCT image of intrahepatic ducts of 5 healthy adults.Results The draining form of left hepatic vein can be divided into 4 types according to the external shape character of left lateral lobe.All veins of the ventral area of segment Ⅷ opened into the middle hepatic vein.All veins of the dorsal area of segment Ⅷ joined the right hepatic vein.However,the veins(V8i) situated between the ventral and dorsal areas of segment Ⅷ can be divided into 3 types on the draining form.Right hepatic vein usually appears on the section through or behind the inferior vena cava with 4 types on the coronal plane.Conclusions Coronal section has obvious advantage to show the course of hepatic veins in the longitudinal direction.Segment Ⅷ can be divided into dorsal and ventral subsegments according to V8i,This method of subsegmental division may contribute to the development of new and safer surgical procedures of the liver.
