Persistent ductus venosus

Case contributed by Sigmund Stuppner
Diagnosis certain


Incidental findings of abnormal vascular hepatic malformation on routine abdominal ultrasound.

Patient Data

Age: 35 years
Gender: Female

The MRI shows a persistent ductus venosus (arrow) that connects the left portal vein with the middle hepatic vein. There is also stenosis of the intrahepatic IVC with intrahepatic adjacent venous collaterals.

The coronal images offer better visualization of the intrahepatic IVC stenosis.

Case Discussion

Abnormal vascular connections are occasionally seen at ultrasonography and require further evaluation. Park et al have categorized intrahepatic portosystemic shunts into four morphologic types. A persistent ductus venosus could be considered as a fifth type of portosystemic shunt.
