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 ...

The significance of the extracranial-intracranial anastomoses of carotid system in occlusion of internal carotid artery

Biomolecules & Biomedicine, 2004
The existence of collateral circulation in patients with impaired intracranial circulation was studied. We analysed angiograms of 35 patients of the Neurology Clinic of Clinical Centre in Sarajevo with occlusion of internal carotid artery.

Sex Differences in Collateral Circulation and Outcome After Mechanical Thrombectomy in Acute Ischemic Stroke

Frontiers in Neurology, 2022
BackgroundCollateral circulation is known to lead to smaller infarct volume and better functional outcome after mechanical thrombectomy (MT), but studies examining sex differences in collateral circulation are scarce.

The Role of Collateral Circulation in Preserving Myocardial Function

Biomolecules & Biomedicine, 2006
The coronary collateral circulation is an alternative source of blood supply to the myocardium jeopardized by the failure of the original stenotic or occluded vessel to provide adequate blood flow to this region. One hundred coronary angiograms and left

S-nitrosylation of AMPKγ impairs coronary collateral circulation and disrupts VSMC reprogramming

EMBO Reports, 2023
Collateral circulation is essential for blood resupply to the ischemic heart, which is dictated by the contractile phenotypic restoration of vascular smooth muscle cells (VSMC). Here we investigate whether S-nitrosylation of AMP-activated protein kinase (

Relevance of peripheral inflammation indexes in different collateral circulation for intracranial hemorrhage in acute anterior circulation ischemic stroke patients undergoing endovascular treatment

Journal of Stroke and Cerebrovascular Diseases
Background: Asymptomatic intracranial hemorrhage (aICH) is common after endovascular thrombectomy (EVT). Collateral circulation could modify the association between aICH with functional outcome and we aimed to investigate the impact of systemic ...
