BACKGROUND AND PURPOSE: The extent of pial collateral formation during acute
ischemic stroke has been shown to influence outcomes. This study examines whether …

BACKGROUND AND PURPOSE: This study examines whether anatomic extent of pial
collateral formation documented on angiography during acute thromboembolic stroke …

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 …

Background: The PROACT II trial showed that intra-arterial thrombolysis (IAT) is effective for
treatment of acute ischaemic stroke attributable to M1 and M2 segment occlusions …

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 AND PURPOSE: A potential role of perfusion CT (PCT) in selecting patients
with stroke for reperfusion therapies has been recently advocated. The purpose of the study …

BACKGROUND AND PURPOSE: Cerebral infarction evolves at different rates depending on
available blood flow suggesting that treatment time windows vary depending on the degree …

BACKGROUND AND PURPOSE: Reteplase (RP) and urokinase (UK) are being used “off-
label” to treat acute ischemic stroke. The safety and efficacy of intra-arterial RP or UK in the …

BACKGROUND AND PURPOSE: Predicting response to rtPA is essential in the era of
endovascular therapy for stroke. The purpose of this study was to elucidate prognostic …

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