Abstract:
Background. Currently, complex liver pathology has imposed an increased need for surgical
interventions at this level, which has required a detailed knowledge of hepatic blood circulation. An
important place in this study belongs to the efferent venous circulation. Under normal conditions, the
liver accumulates about 20% of the circulating blood volume and directs up to 1,200 ml of blood per
minute into the inferior vena cava, which represents 50% of the breast volume returned through this
vein. The advances made lately in knowing the anatomical distribution of the components of the
hepatic, arterial and venous vascular tree have allowed a systematization of knowledge in the field of
liver segmentation.The purpose of the present paper is to study the anatomical and surgical peculiarities
of hepatic veins.
Material and methods. To establish the morphology of hepatic veins, the study was performed on a
number of 11 macroscopic liver preparations. Macropreparations were taken from cadavers of both
sexes who died at different ages, in which no diseases of the hilar or cavale area of the liver.
As working methods were used: plastic injection, which has solvent dust and green, yellow, blue and
red paint, and corrosion step in hydrochloric acid solution.
Results. The trunks of the hepatic veins in all given cases are located intraorganically and flow into
the inferior vena cava in its subdiaphragmatic portion. Depending on the size of the veins, large hepatic
veins with a diameter of 7-18 mm and small diameters of 2-6 mm can be highlighted. The number of
hepatic veins flowing into the inferior vena cava is variable.
Conclusions. The casts of the venous elements of the liver, obtained by polychrome injection and
corrosion are very informative.
