摘要
目的使用CT血管造影(CTA)检查颈动脉狭窄、斑块分布情况,探讨其与ICVD的相关性。方法收集2017年5月至2019年6月在本院确诊的ICVD患者32例以及同期住院进行CTA检查的非ICVD患者32例的临床资料,分为两组。对患者CTA检查图像进行分析,对比两组患者颈动脉狭窄以及颈动脉斑块分布情况。结果CVD组患者无狭窄情况少,占15.62%,低于对照组(59.37%,P<0.05),其中以2级狭窄为多见占31.25%,总狭窄率为84.37%,明显高于对照组(40.62%,P<0.05)。对照组无3级狭窄和完全闭塞情况出现,无狭窄占比59.37%。ICVD组有93.75%(30/32)患者出现斑块,明显高于对照组[46.8%(15/32),P<0.05]。ICVD组斑块84.37%存在于L-CCAI中,其次分别为R-CCAI、L-CCAE、R-CCAE、L-CCA、R-CCA,与对照组情况比,其分布情况差异有统计学意义(P<0.05)。结论颈动脉狭窄、斑块分布与ICVD的发生存在一定相关性,使用CTA检查可反映其颅内外动脉的整体情况,为早期预测ICVD提供可靠信息。
Objective CT angiography(CTA)was used to examine carotid artery stenosis and plaque distribution,and to explore its correlation with ICVD.Methods Clinical data of 32 patients with ICVD diagnosed in our hospital from May 2017 to June 2019 and 32 patients with non-ICVD who were hospitalized for CTA examination during the same period were collected and divided into two groups.The images of the patients’CTA examination were analyzed,and the carotid artery stenosis and plaque distribution of carotid artery were compared between the two groups.Results There were a few cases without stenosis in the CVD group,accounting for 15.62%,which was lower than that of the control group(59.37%)(P<0.05).Among them,stenosis of grade 2 was more common,accounting for 31.25%,and the total stenosis rate was 84.37%,which was significantly higher than that of the control group(40.62%)(P<0.05).There were no stenosis of grade 3 and complete occlusion in the control group,and the cases without stenosis accounted for 59.37%.In the ICVD group,93.75%(30/32)patients had plaques,which was significantly higher than that in control group[46.8%(15/32)](P<0.05).84.37%of the plaques in the ICVD group were present in L-CCAI,followed by R-CCAI,L-CCAE,R-CCAE,L-CCA,and R-CCA,respectively.Compared with the situation in the control group,the difference in distribution was statistically significant(P<0.05).Conclusion Carotid artery stenosis and plaque distribution are related to the occurrence of ICVD.CTA examination can reflect the overall situation of intracranial and extracranial arteries,providing reliable information for early prediction of ICVD.
