| Objective: High Resolution Vessel Wall Imaging(HR-VWI)was used to analyze the wall enhancement characteristics of unruptured intracranial aneurysms,to explore its correlation between clinical risk features of aneurysm patient and morphological features and the PHASES score of aneurysms,and further to determine the relevant factors of aneurysm wall enhancement.Methods: Sixty-seven patients with unruptured intracranial aneurysms were diagnosed by digital subtraction angiography examination in our hospital from December 2018 to January 2021.All patients were evaluated using the pre-and post-contrast HR-VWI.The HR-VWI images were reliably analyzed by two senior radiologists and to determine whether the wall of unruptured intracranial aneurysms was enhanced,which was divided into two groups: enhanced(AWE)group and non-enhanced group.Univariate and multivariate Logistic regression analysis were used to study the factors of aneurysm wall enhancement in UIAs.Results: The AWE group accounted for67.1%,and the non-enhanced group 32.9% respectively.Univariate analysis indicated that the two groups samples were statistically significant(P < 0.05)in aneurysm-related symptoms,neck width,dome height,SR,aneurysm size and the risk score of UIAs.Multivariate analysis showed that aneurysm size(OR = 2.250,P < 0.05)was considered to be independent risk factors for aneurysm wall enhancement.There were no statistically significant differences in sex,age,hypertension history,diabetes history,smoking history,drinking history,SAH history,aneurysm location,aneurysm irregular morphology,and aneurysm diameter between the two groups(P > 0.05).Conclusion: HR-VWI showed that there was a significant correlation between AWE and the size of UIAs,and AWE was detected more frequently in UIAs with high rupture risk based on the PHASES score,indicating that HR-VWI can effectively evaluate and predict the stability of UIAs,and AWE may be a risk factor for instability or even rupture of UIAs. |
