摘　　要：目的:探讨肠系膜上动脉栓塞的CT表现特点。方法:搜集肠系膜上动脉栓塞病例6例,男4例,女2例,平均年龄63岁,其中5例手术证实,1例DSA证实。6例均行腹部平扫加增强CT扫描。结果:肠系膜上动脉内充盈缺损6例,肠壁增厚4例,肠系膜增厚、血管增粗3例,肠腔扩张、肠壁薄纸样改变2例;腹腔积液2例。结论:多层螺旋CT是诊断肠系膜上动脉栓塞的一种有效且无创伤的影像检查方法,可以明确阻塞动脉的部位及范围,对手术较有指导价值。Objective：To investigate the characteristics of CT manifestations of superior mesenteric artery infarction. Methods：Of 6 patients with superior mesenteric artery infarction （4 male,2 female,mean age 63 years）,5 cases were proved by operation, 1 case by DSA. All cases received contrast-enhanced CT examination. Results：CT imaging showed filling defect in mesenteric artery （n= 6）, bowel wall thickening （n= 4）, mesenteric and vessel thickening （n = 3）, dilatation of bowl loops and the thinning of bowel wall （n= 2）,and ascites （n= 2）. Conclusion： MSCT is an effective non-invasive method for diagnosing superior mesenteric artery infarction. It shows definite position and extent of artery occlusion which is valuable to the operation.
