Hepatic and Ductus Venosus Blood Flows During Fetal Life
Abraham M. Rudolph – 1 January 1983 – The course of the venous circulation in the fetal liver has been studied in fetal lambs by means of the radionuclide‐labeled microsphere technique. About 50% of umbilical venous blood passes through the ductus venosus, while the remainder is distributed to both lobes of the liver. Portal venous blood is largely distributed to the right lobe of the liver, with a small proportion passing through the ductus venosus and none to the left lobe. Because of these flow patterns, oxygen saturation is lower in the right than in the left hepatic vein.
