Abnormal ductus venosus waveforms can arise in a number of conditions ranging from aneuploidy to vascular malformations and fetal tumours. 

Abnormal waveforms in fetal ductus venosus flow assessment can occur in a number of situations:

Abnormal waveforms include:

Growth restricted fetuses with abnormal ductus venosus flow have worse perinatal outcome compared to those where flow abnormality is confined to the umbilical or middle cerebral artery 8.
