摘要：

目的 探讨64排CT对肠壁缺血性病变的诊断价值及临床意义。方法 选择2014年11月至2016年10月本院收治的40例肠壁缺血性病变患者作为研究对象。本组患者均行手术治疗，手术病理证实为肠壁缺血性病变，术前行64 排CT 影像学检 查，收集患者病理学及64排CT影像学资料，分析64排CT诊断结果与病理学诊断结果符合率，并总结肠壁缺血性病变影像学 特征。结果 40例患者经64排CT诊断检出血管狭窄病变38例，漏诊2例，诊断符合率为95.00%。肠壁缺血性病变C影像学 特征：肠壁环形增厚及分层强化，狭窄，肠壁节段性扩张及肠壁变薄，病变肠段结肠袋消失，肠壁及静脉积气，肠系膜水肿、腹水。结论 64排CT诊断肠壁缺血性病变准确性较高，影像特征性明显，可为肠壁缺血性病变临床诊治提供可靠的参考依据，值得临床推广。

ABSTRACT: Objective To investigate the diagnostic value and imaging features of 64 slice CT in diagnosis of intestinal ischemia lesions. Methods Forty cases of patients with intestinal ischemic lesions admitted from November 2014 to October 2016 in our hospital were enrolled as the research objects. All the patients underwent surgical treatment, and surgical pathology confirmed as intestinal ischemic lesions. The patients accepted 64 -slice CT imaging examination before the surgery. The pathological results and 64-slice CT imaging data was collected, the coincidence rate with pathological results was analyzed, and the imaging features of intestinal ischemic lesions were summarized. Results Of the 40 cases, 38 cases were diagnozed as vascular stenosis with 64-slice CT, 2 cases missed, the diagnostic consistence rate was 95.00%. The CT imaging characteristics of intestinal ischemic lesions included intestinal wall thickening and hierarchical reinforcement, stenosis, segmental dilatation of the intestinal wall and intestinal wall thinning, intestinal lesions of colonic pouch disappearing, intestinal wall and mesenteric venous gas, mesenteric edema and ascites. Conclusion 64-slice CT has high accuracy in the diagnosis of intestinal wall ischemia, and the imaging features are obvious, which can provide a reliable reference for the diagnosis and treatment of intestinal ischemic lesions, it is worthy of clinical promotion.
