高分辨磁共振血管造影检查颈动脉粥样斑块与缺血性脑血管病相关性分析

目的　观察缺血性脑血管病患者颈动脉粥样硬化发生情况,探讨缺血性脑血管病与颈动脉粥样硬化的关系。方法　采 用磁共振血管成像,对126例经CT、MRI证实的缺血性脑血管病患者和126例非缺血性脑血管病患者的颈动脉硬化情况进行观察, 同时对数据进行统计学分析。结果　在126例缺血性脑血管病患者中,82例有不同程度的颈动脉斑块形成,发生率为68.3%;而非缺 血性脑血管病组126例中仅38例,发生率为35.7%,两组间差异有统计学意义(P<0.01)。结论　磁共振血管造影检查能早期发现 颈动脉粥样硬化,颈动脉硬化斑块与缺血性脑血管病密切相关。

High resolution magnetic resonance angiography in evaluation of relationship between carotid arteriosclerosis and ischemic cerebral vascular disorders

Objective To evaluate the relationship between carotid arteriosclerosis and ischemic cerebral vascular disorders (ICVD). Method We examined 126 ICVD patients and 126 non-ICVD patients in the alterations of carotid dimension and intramembrane morphology with magnetic resonance angiography (MRA). Results Carotid plaques to various extent were detected in 82 cases of ICVD patients and 38 cases of non-ICVD patients. The incidence of carotid plaques was 68.3% and 35.7%, respectively in these two groups of patients. Furthermore, patients either with age over 60 years, hypertension, or hyperlipemia were found to be more susceptible to carotid arteriosclerosis. Conclusion MRA is very useful to detect early-stage carotid arteriosclerosis, and the occurrence in the carotid arteriosclerosis is closely related to ICVD.
