What is "paraumbilical vein"

n. small veins arising in skin around the navel; terminate as accessory portal veins [syn: vena paraumbilicalis]

In the course of the round ligament of liver, small veins (paraumbilical) are found which establish an anastomosis between the veins of the anterior abdominal wall and the hepatic portal, hypogastric, and iliac veins.

The best marked of these small veins is one which commences at the umbilicus and runs backward and upward in, or on the surface of, the round ligament (ligamentum teres) between the layers of the falciform ligament to end in the left portal vein.
