Abstract:
Objective:To investigate the correlation between white matter hyperintensities (WMHs) and collateral circulation in patients with stroke caused by anterior circulation large vessel occlusion (aLVO).Methods:Patients with stroke caused by aLVO treated with endovascular mechanical thrombectomy in the Department of Neurology, Zhengzhou People's Hospital from December 2017 to April 2021 were retrospectively enrolled. Their demography, vascular risk factors, baseline clinical data and Fazekas scale score were collected. Multivariate logistic regression analysis was used to determine the independent correlation between WMHs and the collateral circulation status in patients with aLVO. Results:During the study, 166 patients with aLVO were included (77 males, 46.39%; aged 69.62±5.91 years). Their baseline National Institutes of Health Stroke Scale (NIHSS) score was 9.33±4.42. There were 120 patients (72.29%) in the good collateral circulation group and 46 (27.71%) in the poor collateral circulation group. Univariate analysis showed that there were significant differences in baseline NIHSS score, total Fazekas score and periventricular Fazekas score between the good collateral circulation group and the poor collateral circulation group (all P<0.05). Multivariate logistic regression analysis showed that total Fazekas score (odds ratio 2.583, 95% confidence interval 1.445-4.619; P=0.001) and periventricular Fazekas score (odds ratio 2.190, 95% confidence interval 1.022-4.692; P=0.044) were the independent risk factors for the poor collateral circulation. Conclusion:The severity of WMHs is associated with the poor collateral circulation in patients with aLVO.
