高频超声颈动脉血管重构与老年无症状脑梗死相关性的研究

摘要

目的：通过高频超声探查，分析颈动脉发生血管重构和无症状脑梗死（SCI）间的关系。方法选取38例符合要求的患者成为观察组，再选取同时段健康志愿者38例成为对照组。两组受试者都进行高频超声探查，分析对比两组颈动脉斑块、颈动脉内膜中层厚度（IMT）与颈动脉重构情况。结果与对照组相比，观察组颈动脉斑块检出数量明显增多，斑块的检出率及面积显著增大，斑块评分明显提高，差异均存在统计学意义（P ＜0．05）。两组颈总动脉主干、颈动脉分叉处以及颈内动脉主干 IMT 比较，差异存在统计学意义（P ＜0．05）。观察组较对照组出现颈动脉重构的比例明显提高，两组在无重构及负性重构的发生率方面的差异存在统计学意义（P ＜0．05）。结论高频超声检查可以准确分析颈动脉情况，从而对有效预防无症状性脑梗死发生的临床价值重大。%Objective To investigate the relationship of carotid atherosclerosis’remodeling and silent cerebral in -farction with high frequency ultrasonic.Methods 38 patients were se-lected as the observation group.38 health volunteers were selected as the control group.The Carotid arteries of cases in two groups were al checked with high -frequency ultrasound.The in-spected rate and acreage of the plaques,intima -media thickness(IMT)and vascular remodeling(VR).Results The inspected rate and acreage of the plaques and IMT in observe group were significantly higher than control group(P <0.05).The proportion of carotid atherosclerosis’remodeling in observe group were significantly higher than control group,especial y in no to remod-eling and negative remodeling.Conclusion Carotid artery atherosclerosis can be diagnosed in early period by high resolution color ultrasonography,which is important to prevent the occurrence of cerebral infarction.
