应用彩色多普勒血流成像技术对颈动脉粥样硬化与短暂性脑缺血发作分析

The analysis of using Colored Doppler Blood Stream Image Formation Technology of Neck At-herosclerosis and the transient ischemic attack

目的:对短暂性脑缺血发作病人和无脑卒中病史者进行对照观察。方法:采用彩色多普勒血流成像技术。结果:短暂性脑缺血发作组颈动脉狭窄程度小于49%者与对照组无显著差别。(P<0.05)狭窄程度大于50%者短暂性脑缺血发作组明显高于对照组(P<0.05),发生暂性脑缺血发作的危险是对照组的4.3倍。结论:颈动脉狭窄程度越大,发生暂性脑缺血发作的危险性越大。

Objective： The comparison observation to transient ischemic attack patient and the non -apoplexy medical history to the temporary brain carries. Methods： using colored Doppler blood stream image formation technology. Results： no remarkable difference between the observation group （the narrow degrese is smaller than 49%） and control group. （p〈0.05）.The TIA group （the narrow degree is bigger than 50%）is higher than control group ,the risk is 4.3 times. Conclusion ： The carotid artery narrow degree is bigger, The risk of brain to lack blood is bigger.
