| 目的探讨多层螺旋 CT(MDCT)血管造影及后处理技术对中肠旋转不良的诊断价值。方法选择安徽医科大学第一附属医院 2016年 6月至 2019年 1月 3年期间 13例经临床手术确诊中肠旋转不良的病人，回顾性分析 MDCT影像图像及临床资料。结果 11例出现“漩涡征”阳性率为 85%；3例出现肠系膜动静脉位置“换位征”，阳性率仅为 23%，；10例空肠动脉呈 180° |

| Objective To evaluate the value of multislice spiral CT angiography and post?treatment in the diagnosis of malrotation of midgut.Methods A total of 13 patients with malrotation of midgut diagnosed by clinical surgery in The First Affiliated Hospitalof Anhui Medical University from June 2016 to January 2019 were selected，and the CT images and clinical data were retrospective? ly analyzed.Results Eleven cases presented vortex sign，with a positive rate of 85%.Three cases presented“transposition sign”of the arteriovenous position of mesentery，the positive rate being only 23%.In 10 cases，the jejunal artery was 180° flipped，and the blood vessel was located in the right side of the abdominal cavity，with a positive rate of 77%.The jejunum was located in the rightupper abdominal cavity and ileum in the left lower and middle abdominal cavity in 7 cases.The jejunum was located in the right up?per abdominal cavity and ileum in the right lower abdominal cavity in 5 cases.Abnormal position of ileocecum and appendix wasfound in 2 cases，the positive rate being only 15%，of which abnormality was located in the left lower abdomen in 1 case and theright middle abdomen in the other one.Free transverse colon was found in 3 patients，with a positive rate of 23%.Conclusions MDCT angiography and post?treatment have high value in the diagnosis of malrotation of the midgut，and the mesenteric vortex sign and jejunal artery flip sign have especially certain specificity. |
