目的在肠系膜上动脉夹层(SMAD)诊断中应用128层螺旋CT(MSCT)进行CT血管成像(CTA),并观察其临床价值。方法择取2012年6月至2015年7月于我院就诊的患者30例,这些患者或疑似发生SMAD,或疑似有相关病变。为这些患者行全腹部MSCT扫描,并分析扫描结果。结果患者在MPR图像+CPR图像+CT轴面源像与MIP图像+VR图像中分别出现了明显的内膜瓣阴影、血管瘤样扩张以及真假腔等SMAD表现,可确诊为SMAD。结论经128层MSCT所行CTA技术,可以有效显示患者的SMAD具体病变情况,故临床可将其作为首选检测方法。
Objective To evaluate CT angiography (CTA) with 128-slice spiral CT (MSCT) in the diagnosis of mesenteric artery dissection (SMAD) and to observe its clinical value. Methods Thirty patients were enrolled in our hospital from June 2012 to July 2015. These patients were suspected to have SMAD or suspected related diseases. A total abdominal MSCT scan of these patients was performed and the results of the scan analyzed. Results In patients with MPR images + CPR images + CT axial source images and MIP images + VR images were significantly intimal flap shadow, hemangioma-like dilation and true and false lumen and other SMAD performance can be diagnosed as SMAD. Conclusion The CTA technique of 128-slice MSCT can effectively show the specific lesion of patients with SMAD, so it can be used clinically as the preferred method of detection.
