Collateral Circulation in Ischemic Stroke: An Updated Review. [PDF]
J Stroke, 2023 The collateral circulation plays a crucial role in maintaining perfusion to brain tissue in ischemic stroke, which prolongs the time window for effective therapies to be provided and ultimately avoids irreversible damage that may lead to worse clinical ...

The Pathophysiology of Collateral Circulation in Acute Ischemic Stroke. [PDF]
Diagnostics (Basel), 2023 Cerebral collateral circulation is a network of blood vessels which stabilizes blood flow and maintains cerebral perfusion whenever the main arteries fail to provide an adequate blood supply, as happens in ischemic stroke.

Basic Research in Cardiology, 2008 Following an arterial occlusion outward remodeling of pre-existent inter-connecting arterioles occurs by proliferation of vascular smooth muscle and endothelial cells. This is initiated by deformation of the endothelial cells through increased pulsatile fluid shear stress (FSS) caused by the steep pressure gradient between the high pre-occlusive and ...

Coronary Collateral Circulation [PDF]
Clinical Cardiology, 1991 AbstractThe occurrence and influence of coronary collateral circulation and obstruction of the supplying coronary arteries on left ventricular contractility, prevalence of myocardial infarction, and bicycle exercise ergometer test were studied in a random sample of 286 patients with angiographically documented coronary artery disease.

InceptionV4 and SEResNet101: precise predictors of intracranial hemorrhage and collateral circulation post-ischemic stroke intervention. [PDF]
Front NeurolBackgroundIschemic stroke (IS) is a major global health issue. The risk of intracranial hemorrhage (ICH) after interventional treatment and the status of collateral circulation significantly affect patient prognosis.

Collateral Circulation and <i>Rabep2</i> Polymorphisms in Large Artery Occlusion: Impacts on Short- and Long-Term Prognosis. [PDF]
J Am Heart AssocBackground Intracranial anterior circulation large artery occlusion (AC‐LAO) is a predominant cause of ischemic stroke. Although collateral circulation plays a critical role in stroke outcomes, the genetic and environmental factors affecting collateral ...

Stroke, 2003 Background— The collateral circulation plays a pivotal role in the pathophysiology of cerebral ischemia. Current knowledge of the collateral circulation remains sparse, largely because of prior limitations in methods for evaluation of these diminutive routes of cerebral blood flow.

Effect of collateral circulation in patients with multiple craniocervical artery stenoses. [PDF]
Clin Transl Sci, 2023 Based on previous findings, collateral circulation in the brain is vital in mitigating cerebral ischemia's effects and influencing stroke risk. This retrospective study examined collateral circulation, admission ischemic stroke status, and long‐term ...

ColorViz, a New and Rapid Tool for Assessing Collateral Circulation during Stroke
Brain Sciences, 2020 Prognosis of patients with acute ischemic stroke is strictly related to the patency and prominence of the collateral leptomeningeal pathways distal to the arterial occlusion.
