经颅多普勒、颈动脉彩超和全脑血管造影术在缺血性脑血管病诊断中的应用

Application of TCD,Carotid Ultrasonography with CDFI,and DSA in Diagnosis of Ischemic Cerebrovascular Disease

目的探讨全脑血管造影术(DSA)、经颅多普勒(TCD)和颈动脉彩超(CDFI)在缺血性脑血管病中的应用。方法对56例缺血性脑血管病患者进行DSA、TCD和CDFI检测,观察其异常情况。结果颈部颅外段及颅内段共840根血管中,DSA检测:狭窄42根,闭塞16根;TCD检测:狭窄35根,闭塞27根。颈部颅内段共448根血管中,DSA检测:狭窄16根,闭塞5根;TCD检测:狭窄18根,闭塞10根;CDFI检测:狭窄23根,闭塞4根。结论 DSA、TCD和CDFI 3种方法联合应用,可对缺血性脑血管疾病的病因及诊断作出客观评价。DSA是评价头颈部血管狭窄和选择治疗方案的金标准,它对缺血性脑血管病的进一步治疗起着重要的作用。

Objective To evaluate the application of three dimensional digital subtraction angiography（DSA）,transcranial doppler sonography（TCD） and carotid ultrasonography with CDFI in diagnosis of transient ischemic attack（TIA）.Methods DSA,TCD and carotid ultrasonography with CDFI were performed in 56 patients with carotid disease,and then the abnormalities in carotid artery system were analyzed.Results Among the 840 extracranial and intracranial blood vessels,DSA showed stenosis in 42 and occlusion in 16,and TCD showed stenosis in 35 and occlusion in 27.Among the 448 intracranial blood vessels,DSA revealed stenosis in 16 and occlusion in 5,TCD revealed stenosis in 18 and occlusion in 10,and carotid ultrasonography with CDFI revealed stenosis in 23 and occlusion in 4.Conclusion Combined application of DSA,TCD and carotid ultrasonography with CDFI can make an objective evaluation of the etiology and diagnosis of ischemic cerebrovascular sisease.As the gold standard for the diagnosis and treatment of cerebral or carotid artery stenosis,as well as for the selection of therapeutic regimen,DSA plays an important role in the further interventions of ischemic cerebrovascular disease.
