Diagnosis of Absent Ductus Venosus in a Population Referred for Fetal Echocardiography

Abstract

An ADV should be ruled out in a fetus with unexplained cardiomegaly or dilatation of the umbilical vein, systemic veins, or portal sinus. To our knowledge, prenatal diagnosis of an ADV with an abnormal communication between the portal sinus and the right atrium has not been reported previously. The portosystemic communication persisted after birth and required device occlusion.
