Fig. 30. Three Diagrams of the Umbilical Ring and its Significance in the Development of Ventral Hernia

I. Dissection of the umbilical ring in a human embryo eight months old, viewed from within. The peritoneum and subperitoneal connective tissue, containing a small amount of fat, have been carefully removed, exposing a funnelshaped opening above and to the right of the umbilical arteries. The umbilical vein lies to the left of this weak spot. The umbilical arteries are the strongest structures in the wall of the ring, and a hernial protrusion usually occurs above or to one side of them. Occasionally the umbilical vein is situated to the right of the ring, in which case the weak spot would be on the left side.


II. Side-view of the umbilical ring, showing the favorite position of the small hernial protrusion often seen in newborn babes.


III. A larger hernia, representing a later stage of the same type. Note how the umbilicus becomes lodged at the lower portion of the hernial pouch.
