目的:探讨经颅多普勒超声(TCD)与彩色多普勒超声(CDFI)联合应用诊断颈内动脉起始部(ICAex)重度狭窄或闭塞的意义。方法:对于7例临床经TCD检查诊断为ICAex重度狭窄或闭塞并判断出其侧支建立情况的患者,联合应用CDFI检查。结果:两种检查在诊断血管狭窄和闭塞情况中结论相符,并能相互补充完善。结论:TCD与CDFI联合应用,在ICAex狭窄、闭塞性疾病的诊断中具有重要的临床意义。
Objective: To investigate the significance of transcranial Doppler ultrasound (TCD) and color Doppler ultrasound (CDFI) in the diagnosis of severe stenosis or occlusion of the carotid artery (ICAex). Methods: Seven patients with clinically diagnosed severe ICAex stenosis or occlusion by TCD and diagnosed their collateral establishment were treated with CDFI. Results: The results of the two examinations were consistent in the diagnosis of vascular stenosis and occlusion and could complement each other. Conclusion: TCD combined with CDFI has important clinical significance in the diagnosis of ICAex stenosis and occlusive disease.
