摘要
目的探讨彩色多普勒超声(color Doppler flow imaging,CDFI)与经颅多普勒超声(transcranial Dopplersonography,TCD)联合应用在诊断颅内外动脉狭窄的临床价值。方法对102例缺血性脑血管病患者在数字减影血管造影(digital substraction angiography,DSA)检查前分别行CDFI、TCD检查,其中37例经脑血管造影确定为颈内动脉(ICA)单、双侧狭窄或闭塞,48例颅内动脉狭窄或闭塞。以DSA为标准,计算CDFI、TCD及二者联合检测结果的符合率。结果单用CDFI诊断符合率为93.1%(190/204)、单用TCD为96.2%(1275/1326),二者联合检测CDFI诊断符合率为96.6%(197/204)、TCD为98.4%(1305/1326)。结论CDFI和TCD的联合应用能明显提高对颅内外动脉狭窄诊断的准确性。
Objective: To explore the diagnostic value of combination of color Doppler flow imaging(CDFI)with transcranial Doppler(TCD)in intra-and extra-cranial cerebral arteriostenosis.Methods: One hundred and two patients with cerebral ischemia were examined with CDFI and TCD for examination before digital substraction angiography(DSA).Among them,37 patients were diagnosed as unilateral or bilateral ICA occlusion or stenosis and 48 patients were diagnosed as intra-cranial cerebral artery occlusion or stenosis with D...
