Impacts of Rapid Recanalization and Collateral Circulation on Clinical Outcome after Intraarterial Thrombolysis [PDF]

Journal of Stroke, 2015
Background and PurposeRapid recanalization might improve clinical outcomes after intraarterial thrombolysis (IAT) for acute ischemic stroke patients with collateral circulation. We determined whether rapid recanalization and collateral circulation affect

Merging Multiphase CTA Images and Training Them Simultaneously with a Deep Learning Algorithm Could Improve the Efficacy of AI Models for Lateral Circulation Assessment in Ischemic Stroke

Diagnostics, 2022
We aimed to build a deep learning-based, objective, fast, and accurate collateral circulation assessment model. We included 92 patients who had suffered acute ischemic stroke (AIS) with large vessel occlusion in the anterior circulation in this study ...

Cerebral Collateral Circulation in Carotid Artery Disease [PDF]

, 2011
Carotid artery disease is common and increases the risk of stroke. However, there is wide variability on the severity of clinical manifestations of carotid disease, ranging from asymptomatic to fatal stroke. The collateral circulation has been recognized

Collateral Circulation Characteristic Based on Cone Beam Computed Tomography (Cbct) Images in Hyperacute Stroke

, 2023
Good collateral circulation flow is a promising outcome for ischemic stroke patients. Collateral circulation is the vessels that flow in parallel to each other, perfusing the same target tissue.
