Purpose Fluid-attenuated inversion recovery vascular hyperintensity (FVH) is frequently found in stroke patients after intracranial arterial occlusion, but the prognostic value of FVH findings is unclear. We assessed whether FVH is associated with cerebral collateral status and functional outcome in patients with acute stroke patients receiving endovascular therapy. Methods FVH score, American Society of Interventional and Therapeutic Neuroradiology (ASITN) grade, the functional outcome at 3 months (modified Rankin Scale (mRS)), and other clinical data were collected for 37 acute stroke patients with large vessel occlusion (LVO) receiving MRI before and after endovascular therapy. Statistical analysis was performed to predict functional outcome after stroke. Results The good functional outcome group (n = 16) had a higher FVH1 (FVH before therapy) score (4.63 +/- 1.20 vs 3.14 +/- 1.15; p = 0.001) and ASITN grade (3.31 +/- 0.48 vs 2.00 +/- 1.22; p < 0.001) and a lower FVH2 (FVH after therapy) score than the poor functional outcome group (n = 21; 0.125 +/- 0.50 vs 1.44 +/- 2.16; p = 0.030). mRS at 3 months was negatively correlated with FVH1 (r = - 0.525, p = 0.001) and the ASITN grade (r = - 0.478, p = 0.003) and positively correlated with FVH2 (r = 0.376, p = 0.034). FVH1 (OR, 0.085; 95% CI, 0.013-0.577; p = 0.012) and FVH2 (OR, 2.724; 95% CI, 1.061-6.996; p = 0.037) were independently associated with functional outcome in multivariable logistic regression analysis. Conclusions Assessing FVH before and after therapy in acute stroke patients with LVO might be useful for predicting functional outcome after stroke.
