磁共振血管造影评价颈动脉狭窄与脑梗死发生的相关性研究

目的利用磁共振血管显影评价颈动脉狭窄与脑梗死的相关性。方法对18例颈内动脉供血区脑梗死患者和15例无脑卒中病史的对照组患者进行磁共振血管造影检查,比较脑梗死组与对照组颈动脉形态的差异。结果18例脑梗死患者中颈内动脉轻度狭窄3例,中度狭窄9例,重度狭窄6例,颈动脉粥样斑块15例。15例对照组颈内动脉狭窄程度轻度3例,中度3例,重度0例,颈动脉粥样斑块3例。比较差异有统计学意义(P<0.05)。结论磁共振血管造影可作为检测颈内动脉的狭窄程度的可靠方法,对颈动脉粥样硬化早期干预和脑梗死的预防有重要意义。

The relationship between carotid stenosis with cerebral infarct evaluated by magnetic resonance angiography

Objective To evaluate the relationship between carotid stenosis and cerebral infarct by magnetic resonance angiography.Methods Eighteen cases with cerebral infarct in the regions supplied by internal carotid arteries and 15 cases without cerebral infarct were examined by magnetic resonance angiography,the imagings of carotid arteries of 2 groups were compared.Results Of 18 cases with cerebral infarct,mild stenosis was found in 3 case,moderate stenosis in 9 cases,severe stenosis in 6 cases and atherosclerotic plaque in 15 cases.Of 15 non-infarct cases,mild stenosis was found in 3 cases,moderate in 3 cases,atherosclerotic plaque in 3 cases,and no severe stenosis was found.The difference was statistically significant between 2 groups(P<0.01).Conclusion Magnetic resonance angiography is a reliable method for detecting the degree of carotid stenosis,and can be used as the indicator for early intervention of carotid atherosclerosis and prevention of cerebral infarct.
