Objective:To investigate the correlation between fluid attenuated inversion recovery vascular hyperintensities (FVH) -diffusion weighted imaging (DWI) mismatch and the outcomes after endovascular mechanical thrombectomy (EMT) in patients with acute middle cerebral artery M1 segment occlusive stroke.Methods:Patients with middle cerebral artery M1 segment occlusive stroke who received EMT treatment and whose FLAIR images showed FVH in the Affiliated Hospital of Yangzhou University from January 2016 to June 2020 were enrolled retrospectively. The demographics and basic clinical information of the patients were collected. The modified Rankin Scale was used to evaluate the outcomes at 3 months after the onset of symptoms. 0-2 was defined as a good outcome, and >2 was defined as a poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcome. Results:A total of 77 patients were enrolled in the study. Their age was 67.16±9.63 years, 51 were males (66.23%). The baseline National Institutes of Health Stroke Scale (NIHSS) score was 14.16±7.49. Forty patients (51.95%) had a good outcome, and 37 (48.05%) had a poor outcome. Univariate analysis showed that the proportion of patients with FVH-DWI mismatch in the good outcome group was significantly higher than that in the poor outcome group (60.00% vs. 29.73%; χ2=7.103, P=0.008), and baseline NIHSS score (11.60±4.44 vs. 16.92±9.05; t=-3.312, P=0.001) and the proportion of patients with hypertension (65.00% vs. 86.49%; χ2=4.774, P=0.029) were significantly lower than those in the poor outcome group. Multivariate logistic regression analysis showed that FVH-DWI mismatch was independently associated with the good outcomes (odds ratio [ OR] 0.345, 95% confidence interval [ CI] 0.121-0.984; P=0.047), baseline NIHSS score was independently associated with the poor outcomes ( OR 1.133, 95% CI 1.036-1.239; P=0.006). Conclusion:FVH-DWI mismatch was independently associated with the good outcomes after EMT treatment in patients with acute middle cerebral artery M1 segment occlusive stroke.
