摘　　要：目的了解肠系膜上动脉综合征(SMAS)的多层螺旋CT(MSCT)特征。方法对4例反复发作的餐后上腹饱胀感、呕吐及体质量下降的病人分别行MSCT、上消化道钡餐透视和内镜检查,4例病人均行手术治疗。结果手术证实3例为SMAS,1例为十二指肠腺癌。3例SMAS病人经MSCT确诊,上消化道钡餐透视诊断SMAS病人1例,内镜检查未能作出诊断。SMAS的MSCT表现为胃及十二指肠扩张,腹主动脉-肠系膜上动脉间距离分别为5.0、7.0、7.8mm,其夹角分别为22.0°、20.0°、21.5°。结论 MSCT对SMAS的诊断有重要价值,可成为诊断SMAS的首选方法。Objective To investigate the features of superior mesenteric artery syndrome（SMAS）on multilayer spiral CT（MSCT）. Methods Four patients with repeated postprandial epigastric distension,vomiting and weight loss received MSCT,upper digestive tract barium meal examination and endoscopy.All of them were treated surgically. Results Three cases were confirmed by surgery as having SMAS,and one duodenal cancer.SMAS was indentified by MSCT in three cases,and one by barium meal.Endoscopy failed to make the diagnosis.Manifestations of SMAS on MSCT were gastric and duodenal dilatation,the distance between SMA and abdominal aorta distance was 5.0,7.0and 7.8mm,respectively,and its included angle was 22.0°,2 0.0°,and 21.5°,respectively. Conclusion MSCT is of great value in the diagnosis of SMAS,which may become the first choice for identification of the disease.
