Collateral Circulation in Ischemic Stroke: An Updated Review [PDF]
Journal of 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.

Frontiers in Neurology, 2022 Favorable cerebral collateral circulation contributes to hindering penumbral tissue from progressing to infarction and is associated with positive clinical outcomes after stroke. Given its clinical importance, improving cerebral collateral circulation is

Effect of collateral circulation in patients with multiple craniocervical artery stenoses [PDF]
Clinical and Translational Science, 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 ...

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.

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 ...

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.

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.

Collateral circulation- Evolving from time window to tissue window [PDF]
Annals of Indian Academy of Neurology, 2023 Cerebral collateral circulation refers to the auxiliary vascular structures which compensate cerebral blood flow when it has been compromised due to stenosis or occlusion of the principal supplying arteries.

Acute development of collateral circulation and therapeutic prospects in ischemic stroke
Neural Regeneration Research, 2016 In acute ischemic stroke, collateral circulation plays an important role in maintaining blood flow to the tissue that is at risk of progressing into ischemia, and in increasing the successful recanalization rate without hemorrhagic transformation.
