摘要
目的探讨彩色多普勒超声检测颈动脉硬化斑块在脑梗死中的应用价值。方法选取2016年1月~2017年1月在我院就诊的50例脑梗死患者为观察组,并选择同期非脑梗死体检者50例为对照组,两组患者均采用彩色多普勒超声检查颈动脉检测颈动脉中层内膜厚度(IMT)、斑块类型,并检测收缩期峰值流速(PSV)、舒张末期流速(EDV)、阻力指数(RI)。结果观察组IMT、颈动脉斑块数量、面积[(1.49±0.42)mm、(5.86±1.35)个、(1.48±0.32)cm2]均明显大于对照组[(0.93±0.29)mm、(1.16±0.32)个、(0.59±0.12)cm2](P<0.05或P<0.01);观察组颈动脉斑块不稳定型数量(144个)明显多于对照组(10个)(P<0.01);观察组颈动脉PSV、EDV[(65.35±14.26)cm/s、(16.69±4.36)cm/s]低于对照组[(72.51±14.58)cm/s、(19.11±4.82)cm/s](P<0.05),RI(0.75±0.16)高于对照组(0.65±0.15)(P<0.05)。结论彩色多普勒超声提示颈动脉硬化与脑梗死密切相关,早期检查颈动脉能为临床预防脑梗死发生提供客观依据。
Objective To discuss the application value of color Doppler ultrasonography in detecting carotid atheroscle- rotic plaque in cerebral infarction. Methods 50 patients with cerebral infarction who were diagnosed in of. hospital from January 2016 to January 2017 were selected as the observation group. Another 50 patients with non-cerebral in- farction were selected as the control group. Color Doppler uhrasonography was applied for both groups for the examina- tion of carotid artery. The carotid artery intima thickness（IMT） and plaque type were examined, and the peak systolic velocity（PSV）, end diastolic velocity（EDV） and resistance index（RI） were examined. Results IMT, the number of carotid plaques and area in the observation group were[（1.49：±0.42） ram, （5.86±1.35） and （1.48_±0.32） cm2], which were signifi- cantly higher than those in the control group[（0.93±0.29） ram, （1.16±0.32）, （0.59±0.12） cm2]（P〈O.05 or P〈O.01）; the number of instable carotid plaques in the observation group（144）was significantly higher than that in the control group （10）（P〈0.01）; PSV and EDV of carotid artery in the observation group were[（65.35±14.26） cm/s, （16.69±4.36） cm/s], which were lower than those in the control group[（72.51±14.58） cm/s, （19.11±4.82） cm/s]（P〈O.05）, and RI（0.75±0.16） was higher than that in the control group（0.65±0.15）（P〈0.05）. Conclusion Color Doppler ultrasonography suggests that carotid atherosclerosis is closely related to cerebral infarction. Early examination of carotid artery can provide an objec- ＇i tire basis for the clinical prevention of cerebral infareHon.
