摘要
目的颈部血管彩超对急性缺血性卒中患者前循环脑动脉粥样硬化进行评价,并讨论其临床意义。方法选择患急性前循环脑梗死(影像检查证实)患者在发病后2周内完成颈部血管彩超检查,记录侧颈总动脉/颅外段颈内动脉不同回声斑块出现情况、斑块大小以及不同程度动脉狭窄出现情况。结果CT/MRI阳性侧CCA/EICA和阴性侧比较,CCA/EICA不同回声斑块大小及出现率无统计学差异;50%以下和50%～70%CCA/EICA狭窄出现率两侧无明显差别,70%～90%和90%以上狭窄出现率CT/MRI阳性侧均大于CT/MRI阴性侧。结论颈部血管彩超提示CCA/EICA70%以上狭窄,可以帮助确定急性缺血性卒中"罪犯动脉"。
Objective We appraise cerebral vascular atherosclerosis of acute anterior circulation ischemic stroke patients combining carotid duplex ultrasound.and transcranial Doppler （TCD）, and discuss the clinical significance of the outcomes. Methods Choice before the cycle of acute cerebral infarction （imaging confirmed） in patients with the disease two weeks after the completion of vascular color Doppler ultrasound to check the neck to record lateral carotid artery/extracranial internal carotid artery plaque echo appear different situation, as well as patch size varying degrees, the situation appears artery stenosis. Results CT/MRI positive side CCA/EICA and negative side comparison, CCA/EICA different echo plaque size and rate of no statistical difference; 50%and 50% -70% CCA/EICA stenosis rate was no significant difference on both sides,70% 0 90% and 90% stenosis rate of more than CT/MRI positive side than CT/MRI negative side. Conclusion Neck vascular CCA/EICA 70% color prompted more than a narrow, you can help determine the acute ischemic stroke ＂criminals artery＂.
