Abstract:
Objective To investigate the effect of fluid attenuated inversion recovery (FLAIR) on hyperintense vascular sign in patients with unilateral middle cerebral artery chronic occlusion.Changes of HVS and prediction of cerebral infarction were also analyzed.Methods Patients with unilateral middle cerebral artery chronic occlusion who were hospitalized in Jiangdu People’s Neurology Department of Yangzhou City from July 2016 to August 2021 were enrolled.According to the presence or absence of cerebral infarction,they were divided into non-cerebral infarction group and cerebral infarction group.According to whether the cerebral infarction recurred during the follow-up,the cerebral infarction group was divided into recurrence group and non-recurrence group.Multivariate logistic regression model and ROC curve were used to analyze the risk and predictive value of FVHs and cerebral infarction in patients with unilateral middle cerebral artery chronic occlusion.Results (1)Univariate analysis showed that the fibrinogen level,HVS signs and FVHs score in cerebral infarction group were significantly higher than those in non-cerebral infarction group (P<0.05).The baseline FVHs score of recurrent cerebral infarction patients were significantly higher than that of non-recurrent cerebral infarction patients (P<0.05).(2)Logistic regression analysis showed that FVHs score had a significant independent positive correlation with the first occurrence of cerebral infarction (OR=2.499; 95%CI 1.481~4.218;P=0.001),and FVHs score was not independently associated with cerebral infarction recurrence (OR=1.356;95%CI 0.922~1.994;P=0.112);(3)ROC curve analysis showed that FVHs score ≥4 had certain predictive value for cerebral infarction in patients with unilateral middle cerebral artery chronic occlusion,with sensitivity of 73.3%,specificity of 66.2%,area under curve (AUC) of 0.669 (95%CI 0.476~0.861;P=0.041).Conclusion For patients with unilateral middle cerebral artery chronic occlusion,HVS may change in a process from scratch,and once the occurrence of HVS signs suggests that cerebral blood flow is decompensated,which is prone to cerebral infarction.FHVs score has certain predictive value for cerebral infarction.
