Cerebral collateral circulation is a network of blood vessels which stabilizes blood flow and
maintains cerebral perfusion whenever the main arteries fail to provide an adequate blood …

In acute ischemic stroke, collateral circulation plays an important role in maintaining blood
flow to the tissue that is at risk of progressing into ischemia, and in increasing the successful …

BACKGROUND AND PURPOSE: In acute stroke with proximal artery occlusion, FLAIR
vascular hyperintensities observed beyond the boundaries of the cortical lesion on DWI …

Background: Clinical and biological risk factors for hemorrhagic transformation (HT) after
intravenous thrombolysis (IT) have been well-established in several registries. The added …

BACKGROUND AND PURPOSE: Hyperintense vessels on baseline FLAIR MR imaging of
patients with ischemic stroke have been linked to leptomeningeal collateralization, yet the …

BACKGROUND AND PURPOSE: In acute ischemic stroke, whether FLAIR vascular
hyperintensities represent good or poor collaterals remains controversial. We hypothesized …

Objectives We tested whether FLAIR vascular hyperintensities (FVH)–DWI mismatch could
identify candidates for thrombectomy most likely to benefit from revascularization. Methods …

Background and Purpose—Fluid-attenuated inversion recovery vascular hyperintensities
(FVH) beyond the boundaries of diffusion-weighted imaging (DWI) lesion (FVH-DWI …

Background and purpose To investigate the relation between DWI-PWI mismatch and FLAIR-
hyperintense vessel (FHV) sign and their influence on the prediction of the infarct growth in …

Background and purpose Recent large series studies have demonstrated that dehydration is
common amongst stroke subjects and is associated with poor outcome. However, the effects …
