Background and Purpose—Endovascular strategies provide unique opportunity to correlate
angiographic measures of collateral circulation at the time of endovascular therapy. We …

Background and Purpose—In the Interventional Management of Stroke (IMS) III trial, we
sought to demonstrate evidence of a differential treatment effect of endovascular treatment of …

Background and Purpose—Collateral circulation status at baseline is associated with
functional outcome after ischemic stroke and effect of endovascular treatment. We aimed to …

Background and Purpose—Collateral flow can determine ischemic core and tissue at risk.
Using the Interventional Management of Stroke (IMS) III trial data, we explored the …

Background and Purpose—Collaterals sustain the penumbra before recanalization and
offset infarct growth, yet the influence of baseline collateral flow on recanalization after …

Background and Purpose—Our aim was to determine the relationships between
angiographic collaterals and diffusion/perfusion findings, subsequent infarct growth, and …

Purpose Multiple scores have been described for the assessment of collateralization in
acute ischemic stroke. Currently, there is no gold standard for collateral assessment by CT …

BACKGROUND AND PURPOSE: The relationship between reperfusion and clinical
outcome is time-dependent, and the effect of reperfusion on outcome can vary on the basis …

Background Endovascular reperfusion techniques are a promising intervention for acute
ischemic stroke (AIS). Prior studies have identified markers of initial injury (arrival NIH stroke …

Objective We aimed to investigate the role of pretreatment collateral status in predicting the
efficacy and safety of endovascular treatment (EVT) in acute ischaemic stroke due to cervical …
