目的:探讨颈动脉低回声斑块超声造影增强特征与急性缺血性脑血管病发生的相关性。方法:将164例颈动脉低回声斑块患者(斑块总数164个),根据临床症状及MRI检查结果分为梗死组与非梗死组,梗死组又分为新发梗死组与陈旧梗死组,对斑块超声造影增强特征进行分级,分别比较梗死组与非梗死组、新发梗死组与陈旧梗死组斑块超声造影增强特征。结果:梗死组与非梗死组同侧颈动脉低回声斑块1、3级增强率比较差异有统计学意义(P<0.05),新发梗死组与陈旧梗死组同侧颈动脉低回声斑块1、3级增强率比较差异有统计学意义(P<0.05)。结论:颈动脉低回声斑块超声造影增强程度与急性缺血性脑血管病的发生密切相关。
Objective: To investigate the correlation between the enhanced features of hypoechoic carotid plaque and acute ischemic cerebrovascular disease. Methods: One hundred and sixty-four patients with hypoechoic carotid plaque (164 plaques in total) were divided into infarction group and non-infarction group according to the clinical symptoms and MRI findings. The infarction group was divided into new infarction group and old infarction group, The contrast-enhanced features of plaque were graded to compare the enhanced features of plaque contrast-enhanced ultrasound in infarction group and non-infarction group, new infarction group and old infarction group respectively. Results: There was significant difference in 1,3 and 4 levels of enhancement of ipsilateral carotid artery between infarcted group and non-infarcted group (P <0.05). In new infarction group and old infarction group, ipsilateral carotid artery hypoechoic plaque There was significant difference in 1,3-level enhancement rate (P <0.05). Conclusion: The contrast enhancement of carotid hypoechoic plaque is closely related to the occurrence of acute ischemic cerebrovascular disease.
