Abstract:
Objective To investigate the relationship between extracranial carotid artery tortuosity-related indicators and extracranial internal carotid artery aneurysm(ICAA)in elderly patients with suspected cerebrovascular disease.Methods A retrospective analysis was performed on 124 elderly patients with suspected cerebrovascular diseases undergoing head CT angiography(CTA)in our hospital from January 2021 to December 2023.According to the diagnostic results,they were divided into ICAA group(68 cases)and control group(56 cases).The extracranial carotid artery tortuosity-related indicators were compared between the two groups.Multivariate logistic regression analysis was used to identify the influencing factors for ICAA.ROC curve analysis was employed to analyze the diagnostic value of head CTA parameters for extracranial ICAA,and the area under curve(AUC)was calculated.Results There were no statistical differences in the pro-portions of extracranial internal carotid artery(EICA)without kinking,tortuosity,and coiling be-tween the two groups(P＞0.05).The ICAA group had significantly higher proportion of EICA(32.4％vs 14.3％,P＜0.05),and obviously greater common carotid artery kinking index,EICA kinking index,and internal carotid artery angle than the control group(P＜0.01).Multivariate lo-gistic regression analysis showed that kinking,common carotid artery kinking index,EICA kin-king index,and internal carotid artery angle were influencing factors for ICAA(P＜0.05,P＜0.01).ROC curve analysis indicated that in diagnosing ICAA,the sensitivity and the specificity was 70.59％and 82.14％,respectively,for common carotid artery kinking index,was 83.82％and 87.50％,respectively,for EICA kinking index,and was 80.88％and 83.93％,respectively,for in-ternal carotid artery angle.Conclusion The degree of EICA kinking is correlated with extracranial ICAA,and EICA kinking is more likely to cause ICAA.Head CTA parameters can reflect the morphological features of internal carotid artery kinking and had high adjuvant diagnostic value for diagnosing ICAA.
