摘　　要：目的:探讨脑缺血性卒中患者及其高危人群大脑动脉微栓子的出现频率及临床意义。方法:选择缺血性卒中患者及其高危人群100例作为研究对象。应用德国DWL公司multi DopT1TCD检测仪对被检者进行TCD微栓子监测。结果:微栓子阳性发现率为16% (16 / 100)。房颤组为16. 7% (3 /18);心脏瓣膜病组13. 3% (2 /15);脑梗死组24. 1% (7 /29),短暂性脑缺血发作组14. 2% ( 3 /21 ),颅内大血管狭窄组5. 3% ( 1 /19 )。结论:微栓子阳性率在有潜在栓子来源的患者高于无栓子来源的患者,微栓子的阳性发现率与患者发病后的间隔时间呈负相关。Objective: To study the prevalence and significance of cerebral microembolism in patients with ischemic stroke and people with the high risk. Methods:Total 100 patients were included and embolism signals were detected by using the multi-Dop T1 TCD monitoring. Results: Embolism signals were detected in 16% of patients (16/100). The rate of microembolism was 16.7% in atrial fibrillation group,13.3% in valvular heart disease group,24.1% in territorial infarcts group,14.2% in transient ischemic attack group,5.3% in intracranial arterial stenosis group,respectively. Conclusion:Microembolism signals were prevalent in patients with potential emboli source. There was a negative correlation between microembolism and interval time after the ischemic stroke onset.
