Mesodiverticular band

GF Johnson and AD Verhagen

The mesodiverticular band is an embryologic remnant of the vitelline circulation which carries the arterial supply to the Meckel's diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herinate and become obstruced. Clinical and radiological findings of acute, low, small-bowel obstruction are produced by this band.
