[A rare cause of intestinal obstruction revealed during pregnancy (Kamenge University Hospital Center, Bujumbura, Burundi)].

Acute intestinal occlusion is rare during pregnancy, and more exceptional is the source itself of the occlusion we are reporting embryonic. This is actually an embryonic remains: the omphalo-mesenteric (vitellin) duct that did not resorb and has developed into a fibrous cord. The latter, owing to physiological modifications, is responsible of the occlusion. The authors analyse the two facts which, when associated, represent an interesting clinical fact.
