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.
中憩室带是卵黄循环的胚胎学残余物，它将动脉血供应输送至梅克尔憩室。若退化过程出现差错，一条开放或闭锁的动脉带会持续存在，并从肠系膜延伸至肠系膜对侧憩室的顶端。这会形成一个类似圈套的开口，肠袢可能由此疝出并导致梗阻。这种带子会引发急性低位小肠梗阻的临床和放射学表现。
