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.

An unusual complication of gastric dilatation/volvulus developed in a 10-year-old spayed Great Dane. An aortic thromboembolus lodged in the iliac artery bifurcation 4 days after admission and tube gastropexy to correct the condition. The dog was euthanatized after 48 hours of supportive care failed to elicit any improvement. Thrombus formation appeared to originate in the left ventricle; however, a primary cause could not be determined.

Volvulus of the ascending colon (ACV) in the horse results in microvascular injury and necrosis of the intestinal mucosa. This study investigated the site and type of microvascular injury which occurs within the mucosa and submucosa following ACV. Histopathology of volvulus treated ponies demonstrated mucosal necrosis with microvascular hemorrhage and thrombosis. Thrombi occurred within the subepithelial capillaries and edema and hemorrhage developed throughout the mucosa and submucosa. Vascular casts allowed 3-D viewing of samples obtained from the entire pelvic flexure and demonstrated two distinct microvascular changes: 1) disruption of the colonic glandular capillary network occurred concomitantly with the mucosal injury, and 2) extensive endothelial leakage from the submucosal microvasculature contributes to edema formation. Thus, microcorrosion casting of the equine pelvic flexure provided an effective means to characterize the location and severity of vascular leakage and visualize the extent and severity of injury to the capillary network not easily depicted by histopathology. Microvascular casting in conjunction with routine histopathology provided additional information on the pathomorphologic changes in this model of ischemia/reperfusion injury.
