ABSTRACT
Objective:To investigate the correlation between fluid-attenuated inversion recovery (FLAIR) vascular hyperintensities (FVHs) and outcomes after endovascular mechanical thrombectomy (EMT) in patients with anterior circulation large vessel occlusive stroke.Methods:Using " Nanjing First Hospital Stroke Database" , consecutive patients with anterior circulation large vessel occlusive stroke received EMT treatment from June 2015 to December 2018 were enrolled retrospectively. Before EMT treatment, the distal FVH grade and the American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) collateral circulation grade were evaluated. The modified Rankin Scale was used to evaluate the functional outcome of patients at 3 months after onset, and 0-2 was defined as a good outcome. Spearman correlation analysis was used to analyze the correlation between the distal FVH grade and the ASITN/SIR collateral circulation grade. Multivariate logistic regression analysis was used to identify the independent predictors of the outcomes. Results:A total of 117 patients with acute anterior circulation large vessel occlusive stroke were enrolled, aged 70.74±12.50 years, 72 (61.5%) were male. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 13.73±4.91. Seventy-four patients (63.2%) had a good outcome and 43 (36.8%) had a poor outcome. The distal FVH grade was grade 0 in 8 cases (6.84%), grade 1 in 34 cases (29.06%), and grade 2 in 75 cases (64.10%). Compared with the distal FVH low-grade group (grade 0-1), the high-grade group (grade 2) had a higher ASITN/SIR collateral circulation grade ( P<0.001) and lower baseline National Institutes of Health Stroke Scale (NIHSS) score ( P=0.026). Spearman correlation analysis showed that the distal FVH grade was significantly positively correlated with the ASITN/SIR collateral circulation grade ( r=0.620, P<0.001). Multivariate logistic regression analysis showed that the high distal FVH grade (odds ratio [ OR] 0.336, 95% confidence interval [ CI] 0.128-0.879; P=0.026) was independently associated with the good outcomes, while the higher baseline NIHSS score ( OR 1.036, 95% CI 0.988-1.229; P=0.048) and symptomatic cerebral hemorrhage ( OR 5.597, 95% CI 1.052-29.761; P=0.043) were independently associated with the poor outcomes. Conclusion:The distal FVHs can reflect the state of collateral circulation. The high grade of distal FVHs is associated with the good outcomes after EMT in patients with anterior circulation large vessel occlusive stroke.
