The group of small hepatic veins form the lower group of hepatic veins ‐ participating in the venous drainage (VD) of the caudate lobe (CL) ‐ and the lower portions of right and left hepatic lobes. VDCL was examined by a number of 150 hepatic corrosion casts; the pieces were made by injecting plastic mass in the vascularductal elements of the liver, followed by corrosion of the parenchyma with hydrochloric acid. The number of the CL veins varies from four to fifteen (average of 8.77 veins/piece). The analysis of VDCL depending collector hepatic veins (HV) demonstrates that: the left HV participates in VDCL 17.33% by the tail vein 1.3 (mean 1.80 veins/piece); the middle HV participates in VDCL 100% through the tail vein 4.8 (mean 5.2 veins/piece); the common trunk formed from the middle and left HV participates in the VDCL as a percentage of 11.11%; the right superior HV participates in VDCL as a percentage of 62.67% through the tail vein 2.4 (mean 2.75 veins/piece); the right inferior HV participates in VDCL as a percentage of 12% CL by the tail vein 1.3 (mean 2.22 veins/piece); the Inferior Vena Cava (IVC) venous drainage involved in the CL in 100% of cases, 1.4 veins (veins averaging 1.77 veine/piece). CL main venous drainage is done mainly to the Middle Hepatic Vein (98.46% of the parts) and to the retrohepatic portion of the IVC (84.09%) (Supported by CNMP 41092/2007).
