Persistent right umbilical vein in a fetus with Noonan's syndrome: a case report.
We present a case of persistent right umbilical vein with Noonan's syndrome. Persistence of the right umbilical vein with no intrahepatic portion is an uncommon finding with a review of the literature revealing only five other cases. In these cases drainage was directly into the right atrium, inferior vena cava (IVC) or IVC via the iliac vein. Of the reported cases Noonan's syndrome was confirmed in one case and suspected in a second. This report represents a third case of persistent right umbilical vein with confirmed Noonan's syndrome.
