The Importance of Combining Colour Doppler Flow Imaging and Transcranial Colour Dopple in Diagnosing Aortic Arch Syndrome

目的:探讨经颅多普勒与彩色多普勒超声联合检查头臂型大动脉炎的价值。方法:应用彩超和TCD检查7例头臂型大动脉炎患者的颅内和颅外动脉,分析二维及血流动力学指标。结果:头臂型大动脉炎病变多位于颅外动脉起始段或近心端(84%);颅外段动脉狭窄程度与颅内动脉流速呈大致负相关;结论:彩超与TCD联合检查头臂型大动脉炎,对于了解动脉炎所致血管狭窄的分布情况及分析颅外动脉狭窄或闭塞对颅内循环的影响具有重要诊断价值。

Objective：To investigate the importance of combining color Doppler flow imaging and Transcranial color Doppler for the diagnosis of aortic arch syndrome. Methods： 7 patients with aortic arch syndrome were performed color Doppler flow imaging and Transcranial color Doppler. The two-dimensional and hemodynamic parametes of extra-cranium artery and inter-cranium artery were recorded and analysed. Results： Aortic arch syndrome generally located in the initiation of extra- cranium artery.occupying 84 % （84）%;The degree of extra- cranium artery stenosis has roughly negative correlation with the flow rate of inter- cranium artery. Conclusions： Aortic arch syndrome examined by combining color Doppler flow imaging and TranscranialcolorDopple has important diadynamic value for the distribution of aortic arch syndrome and the influence on structure or emphraxis in extra- cranium artery to inter- cranium artery.
