| 摘 要： | 本文报告用彩色多普勒检测151例颈动脉粥样硬化病变和34例正常人。结果表明颈动脉分叉处是粥样硬化斑块多发部位(62.3%),声像图显示斑块有3种类型(扁平斑、软斑、硬斑)。本组中有6例颈内动脉腔明显狭窄(腔径减少45%以上),狭窄部位显示有镶嵌血流。频谱多普勒分析显示收缩期峰值流速增高和频谱增宽。2例颈内动脉完全阻塞,彩色多普勒显示颈内动脉内无彩色血流。这种方法可用于颈动脉粥样硬化的早期诊断,也对缺血性脑病的预防具有价值。

| Abstract: | In this paper 151 patients with atheroscieroticlesions of earotid artery and 14 normal subjects were de-tected by colour doppler imaging (CDI). The resultsshowed that the carotid bifurcation is the most frequentshe (62.3%) involved by atherosclerotic plaque. Thethree types of plaque (flat, soft, and hard) appeared inultrasonogrophy. There were 6 cases with markedstenosis of the ICA lumen (more than 45% dimeter re-duction), the site of stenosis was elearly visualized byshade of mosaic colour. The spectral doppler ?halysisshowed that the peak of the systolic velocity increasedand the spectrnm broadened. 2 cases of ICA occlusionshow clearly no colour flow in the ICA by CDI. Thism???od can be used to diagnose early atheroscteroticlesions of carotid artery and it is also valuable to pre-vent the ischemic encephalopathy discase attack. |
