主动脉夹层继发破口发生部位与受累分支相关性研究

The Imaging Features of 64-MDCT Angiography in Diagnosis of the Intimal Flap Entry of Aortic Dissection

    摘要
  • 摘要: 目的: 分析主动脉夹层(AD)内膜破口发生部位与主动脉受累分支相关性。方法: 回顾性分析我院2006年1月至2009年12月经64-MDCTA检查诊断为AD及AD术后复查患者71例,结合多种图像后处理技术分析,AD患者内膜破口发生部位与主动脉受累分支轴位出现内膜破口相关性大小。结果: 64-MDCTA轴位图像结合多种图像后处理技术,可明确显示71例患者主动脉剥离内膜破口,共显示内膜破口270个。71例AD患者主动脉分支受累208支,其中,主要分支受累131支(闭塞1支),其中36支受累分支其相应横轴位内膜出现破口,占27.48%,存在弱相关性;主动脉壁支受累77支,其中73支受累分支其相应横轴位内膜出现破口,占94.81%,相关性较好。结论: AD内膜破口发生部位与主动脉受累分支有明显相关性。

     

    Abstract: Objective: To analysis the correlation with the position of the intimal flap entry and the involved aortic branch of aortic dissection(AD). Methods: Seventy-one patients with AD underwent 64-MDCTA examination,and the source images transferred to computer workstation subsequently post-processed using MPR,VR,CPR,MIP. Results: The entry of intimal flap could be shown in all of 71 patients. There were 270 entries of the intimal flap. And there are 208 branch which were involved,at the level of the involved branch,27.84% have entries in the main branch of the aorta,94.81% have entries in the ramiparietals. Conclusion: The position of the entry and the involved aortic branch have high correlation.
