[Malabsorption and complex superior mesenteric vascular anomalies. Apropos of a case].

Radiological, and particularly arteriographic examinations in a 28-year-old man investigated for a malabsorption syndrome with exsudative enteropathy demonstrated the presence of a complex anomaly of mesenteric artery and vein vascularization. The diagnosis, based on these findings, was chronic or recurrent valvulus of the mesentery on an intestinal malposition.
