摘　　要：目的:探讨颈动脉狭窄程度及颈动脉粥样斑块部位、表面形态、性质与缺血性脑梗塞发生的相关性。方法:收集33例急性前循环脑梗塞患者,比较分析梗塞侧与非梗塞侧颈动脉粥样斑块分布、表面形态、斑块内部成分密度及管腔的狭窄程度。结果:脑梗塞侧颈动脉狭窄检出率明显高于非梗塞侧颈动脉狭窄检出率,P<0.05;脑梗塞侧颈动脉重度狭窄或闭塞的几率明显高于非梗塞侧,P<0.05;脑梗塞侧颈动脉斑块检出率明显高于非梗塞侧,P<0.05;脑梗塞侧及非梗塞侧颈动脉规则型斑块、不规则型斑块及溃疡型斑块比例的差异有统计学意义(P<0.05);脑梗塞侧颈动脉不稳定斑块比例明显高于非梗塞侧不稳定斑块比例,差异具有统计学意义(P<0.05)。结论:颈动脉CTA能准确评估颈动脉狭窄程度,正确评价颈动脉斑块的表面形态、性质、类型;颈动脉粥样硬化斑块的形成及动脉管腔不同程度的狭窄是脑缺血性病变的重要危险因素。Objective:To investigate the correlation between the degree of carotid stenosis and the location,surface morphology and properties of carotid atherosclerotic plaque.Methods:Collecting 33 patients with acute Anterior circulation infarction.Distribution of non-infarcted carotid atherosclerotic plaques,surface morphology,plaque internal component density,and stenosis of the lumen.Results:1.The detection rate of carotid artery stenosis in the cerebral infarction was significantly higher than that in the non-infarcted carotid artery stenosis,P<0.05;The risk of severe stenosis or occlusion of the carotid artery in the infarcted side was significantly higher than that in the non-infarcted side.P<0.05;The detection rates of cerebral infarction carotid plaque was significantly higher than that in the non-infarcted side,P<0.05;There were significant differences in the proportion of regular plaques,irregular plaques and ulcerated plaques in the cerebral infarction and non-infarcted carotid arteries,P<0.05;the proportion of unstable carotid plaque in the cerebral infarction was significantly higher than that in the non-infarcted side,P<0.05.Conclusions:Cervical artery CTA can accurately assess the degree of carotid stenosis,correctly evaluate the surface morphology,nature,type of carotid plaque;The formation of carotid atherosclerotic plaque and different degrees of stenosis in the arterial lumen are important risk factors for cerebral ischemic lesions.
