超声评价颈动脉硬化斑块与脑梗死的关系

目的 探讨脑梗死与颈动脉粥样硬化的关系。方法 对84例经CT、MBI证实的脑梗死患者和84例非脑梗死患者行超声检查，观察颈动脉内壁光滑程度和有无动脉粥样硬化斑块。结果 84例脑梗死患者中，58例有不同程度的颈动脉斑块形成，发生率68．3％；非脑梗死组84例中有30例，发生率35．7％，两组间有显著性差异(P＜0．05)。非梗死组60岁以上患者有颈动脉粥样斑块者22例，无粥样斑块者25例；60岁以下患者有颈动脉粥样斑块者8例，无粥样斑块者29例，60岁以上组和60岁以下组在统计学上有显著性差异(P＜0．05)。结论 颈动脉粥样硬化与脑梗死有密切的相关性；年龄越大，颈动脉粥样硬化斑块发生率越高。超声检查能早期发现颈动脉粥样硬化，对有效预防脑梗死的发生有重要意义。

Evaluation of Relationship Between Carotid Arteriosclerosis and Cerebral Infarction with Ultrasonography

Objective To evaluate the relationship between carotid arteriosclerosis(CAS) and cerebral infarction with ultrasonography. Methods All 84 patients with cerebral infarction and 84 patients without cerebral infarction diagnosed by CT and MRI were examined in the alternations of carotid dimension,intramemebrane morphology and hemodynamics with ultrsonography. Results Among 84 and 84 cases from two groups ,56 and 12 cases were found to form carotid plaques to various extent,respectively;the incidence was 68.3% and 35.7% respectively.22 patiens above 60 years from cases without cerebral infarction had carotid plaques,25 patiens above 60 years had not carotid plaques. Those of two groups were different significantly.Conclusion CAS and cerebral infarction are closely related. CAS can be diagnosed in early period by ultrasonography,which is important to pretend the onset of cerebral infarction.
