Ligamentum venosum

Last revised by Daniel J Bell on 30 Aug 2019

The ligamentum venosum is a fibrous remnant which travels superiorly from the porta hepatis of the liver to the inferior vena cava. It is often obliterated in adults. 

In the fetus, it is patent and known as the ductus venosus which shunts blood returning from the placenta in the umbilical vein to the inferior vena cava thus bypassing the liver.
