摘　　要：目的:探究头颈CT血管成像相关指标对脑梗死颈动脉狭窄程度的评估价值。方法:收集本院2020年2月至2023年10月收治的62例脑梗死颈动脉狭窄患者临床资料进行研究,比较头颈CT血管成像与DSA的对脑梗死颈动脉狭窄的诊断情况,比较颈动脉不同狭窄程度的头颈CT血管成像相关指标,分析颈CT血管成像相关指标与脑梗死颈动脉狭窄程度的关系及其对梗死颈动脉狭窄程度的评估价值。结果:62例患者共计256处动脉,其中157处狭窄,99处正常;头颈CT血管成像诊断脑梗死颈动脉狭窄的灵敏度为96.82%,特异度为96.97%,准确性为96.88%,阳性预测值为98.06%,阴性预测值为95.05%,诊断效能良好;颈动脉不同狭窄程度的狭窄远端直径、最小残余直径比较差异显著(P<0.05),狭窄远端直径、最小残余直径随着颈动脉狭窄程度的加重而降低;狭窄远端直径、最小残余直径与颈动脉狭窄程度呈负相关关系,差异显著(r=-0.541,P=0.000、r=-0.519,P=0.001);DSA结果显示,62例患者共有157处不同程度的狭窄,头颈CT血管成像相关指标检测对脑梗死颈动脉狭窄程度的诊断总准确率为92.99%,头颈CT血管成像相关指标对脑梗死颈动脉轻度、中度、重度狭窄的诊断准确率分别为90.63%、93.68%、93.33%;Kappa值=0.819,一致性良好。结论:头颈CT血管成像相关指标对脑梗死颈动脉狭窄程度有良好的的评估价值。Objective:To explore the evaluative value of head and neck CT angiography(CTA)indices in assessing the degree of carotid artery stenosis in patients with cerebral infarction.Methods:Clinical data from 62 patients with cerebral infarction and carotid artery stenosis admitted to our hospital from February 2020 to October 2023 were collected for analysis.The diagnostic performance of head and neck CTA versus digital subtraction angiography(DSA)in identifying carotid artery stenosis in cerebral infarction was compared.CTA indices related to different degrees of carotid artery stenosis were also compared.The relationship between CTA indices and the degree of carotid artery stenosis,as well as their evaluative value,was analyzed.Results:Among the 256 arteries evaluated in 62 patients,157 were stenosed and 99 were normal.Head and neck CTA demonstrated a sensitivity of 96.82%,specificity of 96.97%,accuracy of 96.88%,positive predictive value of 98.06%,and negative predictive value of 95.05%in diagnosing carotid artery stenosis in cerebral infarction,indicating good diagnostic performance.Significant differences(P<0.05)were observed in the distal diameter of stenosis and minimum residual diameter among different degrees of carotid artery stenosis.Both the distal diameter of stenosis and minimum residual diameter decreased with increasing stenosis severity.A significant negative correlation was found between these two indices and the degree of carotid artery stenosis(r=-0.541,P 0.000 for distal diameter of stenosis;r=-0.519,P 0.001 for minimum residual diameter).DSA results showed 157 stenoses of varying degrees in 62 patients.The overall accuracy of CTA indices in diagnosing the degree of carotid artery stenosis was 92.99%.The diagnostic accuracy of CTA indices for mild,moderate,and severe stenosis was 90.63%,93.68%,and 93.33%,respectively.The Kappa value was 0.819,indicating good agreement.Conclusion:Head and neck CTA indices have good evaluative value in assessing the degree of carotid artery stenosis in patients with c
