Abstract: Objective: To explore the finding and diagnostic value of MSCT in intestinal ischemia disease and provide help for clinical treatment. Methods: Retrospective analysis the MSCT plain and enhanced performance of intestinal ischemic lesions in 55 cases were final diagnosed by DSA, surgery, pathology or clinical. Results: Of the 55 patients, there were superior mesenteric artery embolism or thrombosis in 13 cases, mesenteric venous thrombosis in22 cases, ischemic colitis in 2 cases, volvulus in 6 cases, intestinal obstruction in 5 cases, intussusceptions in 4 cases, internal abdominal hernias in 3 cases. The MSCT and CTA findings of the 55 patients, there were lumen expansion and effusion in41 cases, mesenteric edema in 33 cases (cable levy in 5 cases, fat muddy levy in 27 cases, product gas in 1case), mesenteric vascular abnormalities take shape in 17 cases (there were whirlpool sign in 5 cases, abnormal position in 10 cases), vascular stenosis or filling defect in35 cases. Conclusion: MSCT findings of intestinal ischemia lesions has high sensitivity and certain characteristic, it should be as routine and preferred examination, at the same time refer to clinical manifestations, we can make the correct diagnosis and provide the basis for accurate clinical treatment for the important action of the etiologies and differential diagnosis.
