Hepatovenous segments in the human liver.

The patterns of hepatovenous segments in 95 human livers have been studied after preparing corrosion casts of the hepatic veins in 72 specimens and taking X-rays of 23 livers after injecting barium sulphate into the hepatic veins. Five hepatovenous segments were seen in every specimen: left, middle, right, paracaval and caudate. The sizes of corresponding hepatovenous segments were similar in 77.9% of livers; in the remainder increased or decreased size, at the expense of neighbouring segments, was observed.
