CT平扫对肠坏死诊断价值

目的:探讨CT平扫对肠坏死诊断价值,总结肠管坏死征象。方法:分析98例可疑肠坏死患者CT平扫图像,所有患者均经手术证实或未能及时治疗死亡患者CT平扫影像,总结、分析影像特点。结果:全部患者中40例患者存在肠坏死,肠壁厚度改变,包括29例肠壁增厚,8例肠壁菲薄,5例表现为肠壁密度减低,3例表现为肠壁密度增加,25例表现肠管扩张,8例表现肠管塌陷,36例肠管内积液,其中34例见气液平面,4例仅见积气,5例肠壁内见气泡影,38例见腹腔积液,10例见系膜水肿,2例见肠系膜血管密度增高,1例肠系膜静脉内气体,1例门静脉内气体,5例见腹腔游离气体。结论:多排螺旋CT平扫对肠坏死部位及范围的评价有较高的价值,同时CT平扫能明确病因,为及早治疗打下良好基础。

Value of Unenhanced MSCT Scan for Intestinal Necrosis

Objective:To investigate the diagnostic value of CT scan in intestinal necrosis, summed the CT findings of bowel necrosis.Methods:Chose the CT imaging features of 40 patients with enteritis were retrospectively reviewed, some cases were confirmed by surgery, and the other cases were dead without surgery in time. Summarize the characteristics of the images.Results:In 40 patients, 29 were showed wall thickening; 8 cases showed intestinal collapse; 36 cases of the intestinal fluid; 34 cases were seen gas and liquid surface and 4 cases were only seen air. 5 cases were saw the bubble in the intestinal wall. 38 case were seen abdominal cavity effusion. 10 case were seen mesenteric edema. 2 cases were seen the density of mesenteric blood vessels higher than normal vessel. 1 cases were seen some air in mesenteric blood vessels. 1 cases were seen some air in The portal vein. 5 cases were seen free intraperitoneal air.Conclusion:MSCT has high value in evaluating position and size of bowel necrosis and CT could help us know which reason cause the bowel necrosis, so that the disease could be cured timely.
