Background In stroke patients, collateral flow can rapidly be assessed on computed
tomography angiography (CTA). Aims In this study, the impact of baseline collaterals on …

Background: We studied the impact of collateral circulation on CT perfusion (CTP)
parametric maps and the amount of salvaged brain tissue, the imaging and clinical outcome …

BACKGROUND AND PURPOSE: Collateral circulation is an important determinant of stroke
outcome. We studied the impact of leptomeningeal collateral circulation with respect to the …

Background and Purpose—Collateral flow plays an important role in maintaining tissue
viability in proximal large vessel occlusion. We developed and tested a regional …

We tested the hypothesis that the type of vascular occlusion, recanalisation and
collateralisation are predictive of outcome after thrombolytic therapy in acute ischaemic …

Collateral circulation affects the prognosis of patients with acute ischemic stroke (AIS)
treated by thrombolysis. The present study performed a systematic assessment of the impact …

Background and Purpose—In acute ischemic stroke, large early infarct size estimated by the
Alberta Stroke Program Early CT Score (ASPECTS) is associated with poorer outcomes and …

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

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 …

Background: Final infarct volume after thrombolysis for acute ischemic stroke depends on
time to, and degree of reperfusion and residual blood flow, which is influenced by …
