Intrahepatic topography of portal vein in the chick (Gallus gallus domesticus).
50 corrosion casts of Chick portal vein were studied to observe the various intrahepatic patterns of portal vein. The liver was supplied by right and left portal veins. Each one entered the liver through separate hilus. The right lobe of the liver received its portal supply from 2 principal veins: a right dorsal and a right ventral. In addition to the above 2 principal veins 2 minor veins were also observed in majority of cases--one supplied the central region (68%) and other the ventral region (52%) of the right lobe. The left lobe of the liver received its portal blood through left dorsal, left ventral and left intermediate veins. The various sites of origin of the veins of the portal system have been described.
