Background and Purpose—Although collateral vessels have been shown to be an important
prognostic factor in acute ischemic stroke, patients with lack of collaterals on standard …

BACKGROUND AND PURPOSE: Collateral vessel status is strongly associated with clinical
outcome in ischemic stroke but can be challenging to assess. The aim of this study was to …

Purpose Collateral circulation plays a pivotal role in the pathophysiology of acute ischemic
stroke and is increasingly recognized as a promising biomarker for predicting the clinical …

Background and Purpose—Despite the abundance of emerging multimodal imaging
techniques in the field of stroke, there is a paucity of data demonstrating a strong correlation …

Abstract Background & Purpose: Perfusion collateral index (PCI) has been recently defined
as a promising measure of collateral status. We sought to compare collateral status …

Background and Purpose—Status of collateral circulation is a strong predictor of outcome
after acute ischemic stroke. Our aim was to compare the predictive value of strategies for …

The cerebral collateral circulation is the main compensatory mechanism that maintains the
ischemic penumbra viable, the tissue at risk for infarction that can be saved if blood flow is …

BACKGROUND AND PURPOSE: Good CTA collaterals independently predict good
outcome in acute ischemic stroke. Our aim was to evaluate the role of collateral circulation …

Collateral circulation is a potent predictor of revascularization and clinical outcomes after
acute ischemic stroke, and various features of collateral flow may be seen with a variety 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 …
