高频超声对腔隙性脑梗死与颈动脉粥样硬化相关性的研究

目的探讨腔隙性脑梗死与颈动脉粥样硬化的关系。方放64例高血压患者及32例健康人接受颈动脉超声检查，对高血压患者颈动脉粥样硬化斑块与腔隙性脑梗死的关系进行相关分析。结果腔梗组及单纯高血压组内-中膜厚度（IMT）、IMT增厚发生率、斑块发生率均明显高于正常对照组（P〈0．01）。腔梗组斑块发生率明显高于单纯高血压组（P〈0．005）。在64例高血压患者中，检出斑块组腔隙性脑梗死发生率明显高于未检出斑块组（P〈0．01）。结论腔隙性脑梗死与颈动脉粥样硬化，尤其是动脉粥样斑块的发生及严重程度密切相关。

A Study of the Correlation Between Lacunar Infarct and Carotid Atherosclerosis by High- resolution Ultrasound

Objective To investigate the relationship between lacunar infarct and carotid atherosclerosis.Methods Carotid arteries were investigated with high-resolution ultrasound in 64 subjects with hypertension and 32 normal subjects.Correlation analysis were carried out in the correlation between the occurrence of carotid plaques and lacunar infarct.Results IMTs、IMT and the percentage of the occurrence of plaques in group Ⅰ(32 subjects with hypertension and lacunar infarct) and group Ⅱ(32 subjects with hypertension without cerebrovascular) were significantly higher than in group Ⅲ(32 normal subjects)(P<0.01).While the percentage of occurrence of plaques in group Ⅰ were significantly higher than in group Ⅱ(P<0.005).There is close correlation between the occurrence of carotid plaques and lacunar infarct.Conclusion There is close correlation between lacunar infarct and carotid atherosclerosis,especially the occurrence and severity of plaques.
