应用64排螺旋CT检测缺血性脑血管病与颈动脉斑块和狭窄的关系

目的探讨缺血性脑血管病与颈动脉斑块以及狭窄的关系。方法以2008年12月~2009年11月在苏大附二院神经内科住院的143例缺血性脑血管病患者为实验组;以同期67例无缺血性脑血管病患者为对照组,所有患者均行64排螺旋CT血管造影,检测其双侧颈动脉(颈总动脉、颈内动脉颅外段、颈内动脉颅内段)斑块类型以及狭窄程度。结果 143例缺血性脑血管病患者中,仅有14例(9.8%)患者未检测出明显斑块,斑块发生率为90.2%,各段颈动脉斑块检出率均明显高于非缺血性脑血管病患者。18.2%缺血性脑血管病患者存在轻度颈动脉狭窄,23.1%患者存在中度颈动脉狭窄,18.9%患者存在重度颈动脉狭窄,颈动脉完全闭塞的患者占8.4%,缺血性脑血管病患者颈动脉狭窄检出率(68.6%)明显大于非缺血性脑血管病患者(29.9%),两者差异具有显著统计学意义。结论颈动脉斑块的形成和颈动脉狭窄是造成缺血性脑血管病的主要原因。颈内动脉的狭窄比颈总动脉常见,且在颈内动脉颅内段,斑块以硬斑块为主,在颈总动脉中,尽管狭窄较颈内动脉相对少,但是斑块类型以软斑块为主,由此可推断在国人,造成缺血性脑血管病的主要原因为颈总动脉不稳定斑块的脱落和颈内动脉本身狭窄所致。

Relationship between ischemic cerebrovascular disease and carotid plaque and stenosis detected by 64-slice spiral CT

Objective To discuss the relationship between ischemic cerebrovascular disease and carotid plaque and stenosis.Methods 143 cases of ischemic cerebrovascular disease from December 2008 to November 2009 in our hospital were taken as the experimental group,and during the same period,67 cases of patients with no ischemic cerebrovascular disease were taken as the control group.All patients underwent 64-slice spiral CT angiography to detect the bilateral carotid arteries(common carotid artery,extracranial and int...
