Abnormal ductus venosus waveforms

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

Pathology

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

Radiographic features

Abnormal waveforms include

Treatment and prognosis

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.
