目的探讨颈动脉超声和经颅多普勒超声联合应用在脑梗死患者动脉硬化中的检查意义。方法 200例脑梗死患者,均进行颈动脉超声和经颅多普勒超声联合检查。观察颈内动脉狭窄或颈动脉斑块形成情况。结果颅内动脉狭窄阳性患者共80例,其余120例患者提示为阴性,分别占40%和60%;提示为颈动脉斑块形成阳性患者共116例,阴性患者共84例,分别占58%和42%;提示颈内动脉狭窄或颈动脉斑块形成阳性患者共150例,阴性患者共50例,分别占75%和25%;提示为颅内动脉狭窄或颈动脉狭窄阳性患者共66例,阴性患者共134例,分别占33%和67%。颈动脉斑块形成所占比例高于颈内动脉狭窄所占比例,差异有统计学意义(P<0.05);颈内动脉狭窄或颈动脉斑块形成所占比例分别高于颈内动脉狭窄或颈动脉斑块形成,差异有统计学意义(P<0.05)。结论在脑梗死患者中,颈内动脉狭窄或颈动脉斑块形成较为常见,颈动脉超声和经颅多普勒超声联合应用有助于评估患者病情。 Objective To investigate the significance of combined carotid artery and transcranial Doppler ultrasonography in atherosclerosis in patients with cerebral infarction. Methods 200 patients with cerebral infarction were examined by carotid ultrasonography and transcranial Doppler echocardiography. Observation of internal carotid artery stenosis or carotid plaque formation. Results A total of 80 patients with positive intracranial stenosis were found. The remaining 120 patients showed negative results, accounting for 40% and 60% respectively. It was suggested that there were 116 positive carotid plaque-positive patients and 84 negative patients, accounting for 58% And 42% respectively. There were 150 cases of carotid artery stenosis or carotid artery plaque positive, and 50 cases of negative patients (75% and 25% respectively) .There were 66 patients with positive intracranial stenosis or carotid artery stenosis , A total of 134 negative patients, accounting for 33% and 67%. The proportion of carotid artery plaque formation was higher than that of internal carotid artery stenosis, the difference was statistically significant (P <0.05); the proportion of internal carotid artery stenosis or carotid plaque formation was higher than that of internal carotid artery stenosis or Carotid plaque formation, the difference was statistically significant (P <0.05). Conclusion In patients with cerebral infarction, carotid artery stenosis or carotid plaque formation is more common, carotid artery ultrasound and transcranial Doppler ultrasound combined to help assess the patient’s condition.
