目的探讨超声和多层螺旋CT血管造影(CTA)检测脑梗死病人颅外颈动脉的临床价值,比较两种检查方法的一致性。方法选择2014年1月—2016年6月在我院诊治的临床疑似颈部血管性病变的脑梗死病人80例,所有病人给予超声和CTA检测,比较斑块性质、部位及狭窄情况。结果 80例病人超声和CTA检查发现斑块分别为112处和117处。超声与CTA对颅外颈动脉斑块发生部位、斑块性质与狭窄程度的检出情况比较,差异无统计学意义(P>0.05);Kappa值分别为0.698、0.713、0.745。结论颅外颈动脉斑块和脑梗死关系密切,超声和CTA在检测颅外颈动脉斑块发生部位、斑块;性质与狭窄程度判定表现出良好的一致性,对颅外颈动脉检查具有互补作用。
Objective To investigate the clinical value of ultrasound and multi-slice spiral CT angiography (CTA) in detecting extracranial carotid artery in patients with cerebral infarction and to compare the consistency of the two methods. Methods From January 2014 to June 2016, 80 patients with clinically suspected neck vasculopathy who were diagnosed and treated in our hospital from January 2014 to June 2016 were enrolled in this study. All patients were examined by ultrasound and CTA, and the plaque characteristics, location and stenosis were compared. Results Ultrasound and CTA examination of 80 patients revealed that the plaques were 112 and 117, respectively. Ultrasound and CTA had no significant difference in the detection site of extracranial carotid plaque, plaque quality and stenosis (P> 0.05). The Kappa values were 0.698, 0.713 and 0.745 respectively. Conclusion Extracranial carotid artery plaque is closely related to cerebral infarction. Ultrasonography and CTA are used to detect the site and plaque of extracranial carotid artery plaque. The nature and extent of stenosis are consistent with each other, and they are complementary to extracranial carotid artery effect.
