An anomaly of the position of the midgut in a pregnant woman predisposes to volvulus. Vascular repair, despite the abdominal catastrophe, sometimes allows parts of the intestine to be saved. A case of volvulus in a pregnant woman is described. At operation, 18 hours after onset, two anomalies were found: reverse rotation of the midgut and an anomaly of the collecting system of the superior mesenteric vein. Most of the midgut was infarcted. Thrombi were removed from the superior mesenteric vessels, and a portion of the anamalous superior mesenteric vein was reconstructed. All but 3 M. of the small bowel and the entire right colon were resected. Prolonged treatment with parenteral hyperalimentation enabled us to control the appearance of a moderate degree of malabsorption. To our knowledge, no similar case has been reported previously in the literature.

Ileal villous atrophy with normal proximal small intestinal mucosa is a rare lesion observed in a few diseases. We report here a case of unknown etiology. A 49-year-old woman presented with chronic diarrhea and steatorrhea due to bile acid malabsorption which was strikingly improved by a low-fat diet. Villous atrophy was total or subtotal, but enterocyte alterations were minimal. Crypts were hyperplastic and the lamina propria was infiltrated by lymphocytes and plasma cells mainly synthesizing IgM. These alterations were associated with the presence in the submucosa, and occasionally in the mucosa, of numerous convoluted nonectasic capillary tufts. Thrombi consisting of pure platelet aggregates were found in the capillary tufts and adjacent small vessels, whose walls were either normal or hyalinized. The patient suffered for many years from attacks of Raynaud's phenomenon and platelet aggregation was depressed in the presence of collagen. Thrombi disappeared after aspirin treatment, but the other lesions persisted at the time of death from an unrelated cause.
