Background Since the introduction of the philosophical tenet “Time is Brain!,” multiple lines
of research have demonstrated that other factors contribute to the degree of ischemic injury …

Purpose of Review To explore factors associated with infarct progression in the early and
late phase of acute ischemic stroke in patients undergoing endovascular therapy. Recent …

Objective To test the hypothesis that patients with acute ischemic stroke with poorer
collaterals would have faster ischemic core growth, we included 2 cohorts in the study …

Background and Purpose—In the setting of acute ischemic stroke because of large-vessel
occlusion (LVO) there is progressive loss of brain tissue which occurs in a time-dependent …

Background and Objectives The optimal methods for predicting early infarct growth rate
(EIGR) in acute ischemic stroke with a large vessel occlusion (LVO) have not been …

Blood supply to the brain is secured by an extensive collateral circulation system, which can
be divided into primary routes, ie, the Circle of Willis, and secondary routes, eg, collaterals …

Background and Purpose—Large vessel occlusion stroke leads to highly variable
hyperacute infarction growth. Our aim was to identify clinical and imaging parameters …

Background and Purpose Infarct growth rate (IGR) in acute ischemic stroke is highly
variable. We sought to evaluate impact of symptom-reperfusion time on outcomes in patients …

Leptomeningeal anastomoses or pial collateral vessels play a critical role in cerebral blood
flow (CBF) restoration following ischemic stroke. The magnitude of this adaptive response is …

Purpose This study compares computed tomography angiography-based collateral scoring
systems in regard to their inter-rater reliability and potential to predict functional outcome …
