title: [Vascular malformations of the digestive tract: a cause of severe digestive hemorrhage. Apropos of 2 cases].
abstract: We report on two cases of angiodysplasia of the digestive tract complicated by serious acute bleeding. The preoperative diagnoses were made by angiography. One case concerned a voluminous jejunal lesion which was macroscopically visible; the other concerned a punctiform lesion detected only by angiography and not found on the pathology specimen. The authors insist on the potential gravity of these angiodysplastic lesions, the necessity to perform an emergency celio-mesenteric angiogram when confronted with a serious digestive tract hemorrhage non-explained by conventional methods of exploration when they can be performed.
