|contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!|
Ductus Venosus describes the vitelline blood vessel lying within the liver that connects (shunts) the portal and umbilical veins to the inferior vena cava and also acts to protect the fetus from placental overcirculation.
Absence can cause hydrops fetalis and the umbilical vein then drains directly into the inferior vena cava or right atrium. Postnatally this shunt functionally closes then structurally closes and degenerates to form it the ligamentum venosum. Failure to close is described as a persistant ductus venosus.
