The coronary collateral circulation revisited [PDF]
Netherlands Heart Journal, 2013 The coronary collateral circulation constitutes a vascular network that forms bridges between adjacent arteries. In response to obstructive coronary artery disease (CAD) due to atherosclerotic plaque progression, these bridging vessels enlarge by a complex interplay of physical forces along with molecular and cellular players.

Guidelines for evaluation and management of cerebral collateral circulation in ischaemic stroke 2017
Stroke and vascular neurology, 2018 Collateral circulation plays a vital role in sustaining blood flow to the ischaemic areas in acute, subacute or chronic phases after an ischaemic stroke or transient ischaemic attack.

A Deep Learning Approach to Predicting Collateral Flow in Stroke Patients Using Radiomic Features from Perfusion Images [PDF]
arXiv, 2021 Collateral circulation results from specialized anastomotic channels which are capable of providing oxygenated blood to regions with compromised blood flow caused by ischemic injuries. The quality of collateral circulation has been established as a key factor in determining the likelihood of a favorable clinical outcome and goes a long way to determine

Stroke, 2019 Background and Purpose- Peripheral immune cells are activated after stroke and may in turn influence the fate of ischemic brain tissue, thus exerting a dual role in ischemic stroke.

Tomography, 2022 Up to 30% of ischemic stroke cases are due to large vessel occlusion (LVO), causing significant morbidity. Studies have shown that the collateral circulation of patients with acute ischemic stroke (AIS) secondary to LVO can predict their clinical and ...

Sensitivities and Hedging of the Collateral Choice Option [PDF]
arXiv, 2022 The collateral choice option allows a collateral-posting party the opportunity to change the type of security in which the collateral is deposited. Due to non-zero collateral basis spreads, this optionality significantly impacts asset valuation. Because of the complexity of valuing the option, many practitioners resort to deterministic assumptions on ...

International Journal of Molecular Sciences, 2019 Cardiovascular disease remains the leading global cause of death, and the number of patients with coronary artery disease (CAD) and exhausted therapeutic options (i.e., percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and ...

Theranostics, 2019 Rationale: Brain collaterals contribute to improving ischemic stroke outcomes. However, dynamic and timely investigations of collateral blood flow and collateral restoration in whole brains of living animals have rarely been reported.

Cheapest-to-Deliver Collateral: A Common Factor Approach [PDF]
arXiv, 2021 The collateral choice option gives the collateral posting party the opportunity to switch between different collateral currencies which is well-known to impact the asset price. Quantification of the option's value is of practical importance but remains challenging under the assumption of stochastic rates, as it is determined by an intractable ...
