| 目的探讨彩色多普勒诊断颈内动脉狭窄的方法及准确性。方法采用彩色多普勒检测83例颈动脉硬化症患者,128侧颈内动脉起始处有不同程度狭窄。按狭窄程度分成三组,轻度（1～39%）69侧,中度（40～69%）44侧,重度（70～99%）15侧。测定颈内动脉收缩期峰值流速（ICASPV）及颈内动脉与颈总动脉流速之比（VI CA/CCA）.结果轻度狭窄时血流无明显改变,中度狭窄时,ICASPV及VICA/CCA轻度增加；重度狭窄时,狭窄口呈现五彩色血流信号,ICASPV及VICA/CCA均明显增加；尤以VICA/CCA敏感。部分超声检测结果与动脉造影及/或手术对照符合率为89.71%.结论超声检查诊断颈内动脉起始处狭窄准确、无创,可作为临床首选方法；判断狭窄程度应以颈内与颈总动脉流速之比作为主要依据,结合峰值流速及二维切面图检测情况；中度狭窄,VICA/CCA>1.4,ICASPV>95cm/s;重度狭窄,VICA/CCA>3.0,ICASPV>200cm/s. |

| Objective To determine method and accuracy of color Doppler in diagnosing the stenosis of internal carotid artery.Methods We detected 128 internal carotid arteries with atherosclerotic stenosis in 83 cases by color Doppler.All studies were divided into three groups upon the degree of stenosis:slight (1～39%)69;moderate (40～69%)44; severe (70～99%)15.Peak systolic velocity in internal carotid artery (ICASPV) and ratio of internal carotid artery velocity to common carotid artery velocity (VICA/CCA) were measured.Results No significant hemodynamic changes occurred in slight group;ICASPV and VICA/CCA elevated slightly in moderate group;the color mosaic were presented in severe group,ICASPV and VICA/CCA were increased significantly,especially VICA/CCA.A part of results were compared with digital subtraction angiography (DSA) and/or operation.The accuracy was 89.71%.Conclusion Sonographic scanning is an accurate,noinvasive method in diagnosing the internal carotid artery stenosis and may be selected primarily in clinic.Determination of stenosis should be upon VICA/CCA,combining with the ICASPV and 2 D scanning,moderate stenosis:VICA/CCA>1.4,ICASPV>95cm/s;severe:VICA/CCA>3.0,ICASPV>200cm/s. |
