16层螺旋CT对肠系膜上动脉夹层的诊断价值

摘要

目的：探讨16层螺旋C T血管成像对肠系膜上动脉夹层的诊断价值和意义。方法回顾性分析黄石中心医院普爱院区2010年1月至2012年12月收集的9例确诊的肠系膜上动脉夹层患者的16层螺旋C T血管成像影像表现，运用后处理技术如最大密度投影、多平面重组、曲面重建和容积再现等方法进行分析和诊断。结果16层螺旋C T血管成像及后处理技术均能显示肠系膜上动脉夹层的真假腔、内膜片、破裂口位置、夹层累计的范围及是否合并血栓、分支血管受累等病变。结论运用16层螺旋CT血管成像及后处理技术能清楚显示肠系膜上动脉夹层及邻近血管病变，对筛选和诊断肠系膜上动脉夹层意义重大。%Objective To explore application value of 16 detecter spiral CT angiography for dissecting aneurysm of aorta .Meth-ods Retrospectively analyzed 9 cases of patients with the dissection of superior mesenteric artery in admission from January 2010 to December 2012 ,the cases were diagnosized by 16 detecter spiral CT angiography for dissecting aneurysm of aorta .post-process-ing techniques such as maximum density projection ,multi-plane reorganization and curved surface reconstruction and volume were used analyzed and diagnosized .Results These pathological changes such as superior mesenteric artery sandwich of true ,false cavity and inner diaphragm ,broken mouth position ,sandwich cumulative range and whether merger thrombus ,branch vascular involve-ment could be displayed by 16 detector CT vascular imaging and post-processing technology .Conclusion 16 layer detector CT ima-ging and post-processing techniques of blood vessels could clearly show the mesenteric artery sandwich ,which might be play an im-portant role for timely and accurate diagnosis .
