【摘要】：目的 :比较CT血管造影(CTA)及彩色多普勒血流成像(CDFI)对颈内动脉形态异常的诊断价值,并探讨颈内动脉形态异常与缺血性脑血管病的关系。方法:选取2011年10月—2013年6月经临床诊断为缺血性脑血管病的患者126例,以DSA检查结果为金标准,采用Kappa检验,观察CTA、CDFI对颈内动脉形态异常分型的准确性。将所有患者分成脑梗组、TIA组及无症状组,采用方差分析,观察颈内动脉形态异常与缺血性脑血管病的关系。结果:76条颈动脉的CTA和CDFI分别与DSA比较,Kappa值=0.95和Kappa值=0.88(P0.001),提示两者诊断符合率较高;252条颈动脉的CTA与CDFI比较,Kappa值=0.93(P0.001),提示CTA与CDFI之间具有较高一致性。脑梗组、TIA组及无症状组的颈内动脉形态异常发生率有显著性差异(χ2=16.22,P=0.001),两两比较,脑梗组和TIA组的异常率均高于无症状组,差异有显著性意义,而脑梗组和TIA组异常率之间差异没有统计学意义。结论:CTA和CDFI均可用于评价颈内动脉形态异常。颈内动脉扭曲可能是缺血性脑血管病的危险因素之一。
[Abstract]:Objective: to compare the value of CT angiography (CTAA) and color Doppler flow imaging (CDFI) in the diagnosis of abnormal internal carotid artery morphology, and to explore the relationship between abnormal internal carotid artery shape and ischemic cerebrovascular disease. Methods: 126 patients with ischemic cerebrovascular disease from October 2011 to June 2013 were selected. The accuracy of DSA CDFI in abnormal classification of internal carotid artery was observed by Kappa test. All the patients were divided into two groups: TIA group and asymptomatic group. The relationship between internal carotid artery morphological abnormality and ischemic cerebrovascular disease was observed by ANOVA. Results compared with DSA, the CTA and CDFI of 76 carotid arteries were 0.95 and 0.88, respectively, suggesting that the diagnostic coincidence rate of CTA and CDFI in 252carotid arteries was higher than that of CDFI, suggesting that there was a high consistency between CTA and CDFI. There was a significant difference in the incidence of abnormal internal carotid artery morphology between the TIA group and the asymptomatic group (蠂 ~ (2 +) ~ (2) ~ (16. 22) P ~ (2 +) P ~ (0.001). Compared with the asymptomatic group, the abnormal rate of the cerebral infarction group and the TIA group were higher than that of the asymptomatic group, and the difference was significant. There was no significant difference in abnormal rate between cerebral infarction group and TIA group. Conclusion both CDFI and CTA can be used to evaluate the abnormal shape of internal carotid artery. Internal carotid artery distortion may be one of the risk factors for ischemic cerebrovascular disease.
