Vein connecting umbilicus to liver.

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

A paraumbilical (or umbilical) hernia is a hole in the connective tissue of the abdominal wall in the midline with close approximation to the umbilicus.
