多层螺旋CT评价颈动脉粥样硬化与脑梗死的关系

目的探讨多层螺旋CT评价颈动脉粥样硬化与脑梗死的关系。方法MSCT检测48例脑梗死患者的颈动脉,测量粥样斑块的厚度;并检查37例无脑梗死患者作为对照组。结果在脑梗死组,共有26例发现有斑块形成,检出率为54.2%;对照组共有5例发现有斑块形成,检出率为13.5%,两者有显著差异﹝P<0.01﹞。颈动脉粥样斑块最常见于颈动脉分叉处,其次为颈内动脉起始段。结论颈动脉粥样硬化程度与脑梗死发生率呈正比。MSCT在检出颈动脉粥样硬化斑块和临床疗效观察方面是一种有用的技术手段。

The relationship between the atherosclerosis of carotid artery and cerebral infarction with MSCT

Objective To explore the correlation between cerebral infarction and carotid atheroscleorosis by MSCT. Methods 48 patients with cerebral infarction was performed CT examination in the carotid arteries . The thickness of plaques were measured and compared with 37 cases in the contrast group. Results Twenty-six cases with plaque formation were detected in the cerebral infarction group. The rate of lesion detection was 54.2%. Five plaques formation were detected in the contrast group and the rate of lesion detection was 13.5%. There was significant difference between the two groups(P<0.01). The most common site of plaque formation is the bulb of the common carotid artery, and then proximal internal carotid artery. Conclusion The degree of carotid atheroscleorsis is in proportion to the incidence rate of cerebral infarction. MSCT is an useful technique in detecting atherosclerosis of the carotid artery, for assessing potential occurrence of cerebral infarction.
