急性脑梗死患者颈动脉彩超检查的临床研究

目的探讨颈动脉彩色多普勒超声检查在急性脑梗死患者中的临床意义。方法对MRI的弥散加权成像证实的86例急性期脑梗死患者(脑梗死组)和72例健康体检者(对照组),采用彩色多普勒超声方法分析患者颈动脉斑块的分布及性质。结果 86例脑梗死患者中,颈动脉斑块发生率为74.4%,对照组中有斑块形成者检出率28.2%,两组相比较差异有统计学意义(P<0.01);斑块多见于颈总动脉分叉处;脑梗死组中不稳定性斑块(软斑、溃疡斑)检出率明显高于对照组,两组对照差异有统计学意义(P<0.01)。结论颈动脉粥样硬化和脑梗死有密切的关系,彩色多普勒超声是检测颈动脉粥样硬化最为简捷的方法,对临床预防脑梗死有重要意义。

Clinical Research of Acute Cerebral Infraction Patients Carotid Artery Color Doppler Ultrasound Inspection

Objective To explore the clinical implications of carotid artery color doppler ultrasonography in acute cerebral infraction patients.Methods The distribution and nature of the carotid atherosclerotic plaques confirmed by MRI diffusion weighted imaging(DWI) were analyzed by color doppler ultrasonography in patients with acute cerebral infarction(n=86) and normal control group(n=72).Results Carotid arteries plaque detection rate was up to 74.4% among 86 cases of cerebral infarction and the normal control group was 28.2%,there was significant difference between the both groups(P<0.01);plaques were in carotid arterial bifurcation place;unstable plaque in the cerebral infarction group(soft spot,ulcer spot) the detection rate were obviously higher than those in the normal control group,there was significant difference between the both groups(P<0.01).Conclusion Carotid atherosclerosis had close correlation to cerebral infraction,Color Doppler ultrasonography was a convenient and effective method to investigate carotid atherosclerosis,it was important to prevent the onset of ischemic infarction.
