The ductus venosus is a fetal vessel that has an important function in transfer of oxygen and nutrition rich blood from umbilical vein to vital organs. Its control under active regulation and its anatomy results in a flow-velocity profile that is typically forward throughout the cardiac cycle. This forward cardiac function reflects afterload, cardiac contractility, compliance and vascular volume changes. Ductus venosus assessment gives valuable information in different fetal conditions. For example, during first trimester screening, an abnormal ductus venosus measurement changes the screening result. Assessment of ductus venosus in twin to twin transfusion syndrome is an essential element of staging. In fetal growth restriction, an abnormal waveform mandates imminent delivery. In this review, we will discuss role of ductus venosus assessment and its role in antenatal management and prediction of outcome in certain fetal conditions throughout the pregnancy.
