颈动脉粥样硬化与脑梗死的关系

目的：探讨颈动脉粥样硬化与脑梗死的关系。方法：82例患者为脑梗死组及74例非脑梗死患者（对照组）分别进行彩色多普勒超声检查。比较两组患者颈动脉粥样硬化的特征。结果：脑梗死组颈内动脉内膜中层厚度（IMT）〉0．8mm（42．68％）与对照组（27．03％）比较差异有显著性（P〈0．05）。脑梗死组中不稳定斑块（软斑50．00％，及溃疡斑17．11％）检出率67．11％，稳定性斑块检出率32．89％；对照组中不稳定斑块（软斑21．05％，及溃疡斑5．26％）检出率26.31％，稳定性斑块检出率73．68％．两组比较差异有显著性（P〈0．05）。斑块好发于颈总动脉膨大处、颈内动脉起始处及颈总动脉主干。结论：颈动脉粥样硬化斑块与脑梗死发生有密切关系．积极采取措施，增强斑块稳定性，防止斑块破裂，可减少脑梗死的发生。

Ralationship between carotid atherosclerosis and cerebral infarction

Objective:To investigate the relationship between carotid atherosclerosis and cerebral infarction.Methods:82 cases with cerebral infarction served as cerebral infarction (IC) group and 74 cases of none cerebral infarction as control group,they were assessed by color doppler and the featues of carotid atherosclerosis in two groups were compared.Results:The medial thickness of inner membrane of carotid artery was found in CI group IMT>0.8 mm(42.68%)] and control group(27.03%),with a significant difference between them(P<0.05).Cerebral infarction was correlated with the type of carotid atheromatous plaque,especially soft plaque and ulcer plaque.There was a high prevalence of carotid plaque in CCA and ICA. Conclusion:There is a significant correlation between cerebral infarction and carotid atheromatous plaque a,enhancing the stability of carotid plaques and the measures in preventing irs rupture can decrease the occurrence of cerebral infarction.
