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。
Objective To investigate the clinical significance of carotid artery color Doppler ultrasonography in patients with acute cerebral infarction. Methods Totally 86 patients with acute cerebral infarction (cerebral infarction group) and 72 healthy controls (control group) were confirmed by diffusion weighted imaging (MRI). The distribution and characteristics of carotid plaques in the patients were analyzed by color Doppler ultrasonography. Results Among the 86 patients with cerebral infarction, the incidence of carotid plaque was 74.4%, while that of the control group was 28.2%. There were significant differences between the two groups (P <0.01) Found in the bifurcation of common carotid artery; cerebral infarction group of unstable plaque (soft spot, ulcer spot) detection rate was significantly higher than the control group, the difference between the two groups was statistically significant (P <0.01). Conclusion Carotid atherosclerosis is closely related to cerebral infarction. Color Doppler ultrasonography is the most simple and effective method to detect carotid atherosclerosis, which is of great significance in the prevention of cerebral infarction.
