Triiodothyronine levels were positively correlated with opening of collateral circulation in cerebral infarction patients with large artery atherosclerosis

open access: yesArchives of Medical Science, 2019
Introduction Non-thyroidal illness syndrome (NTIS) is one of the signs for poor prognosis of cerebral infarction (CI), but its risk factors had never been explored.

Acute Stroke Multimodal Imaging: Present and Potential Applications toward Advancing Care. [PDF]

open access: yes, 2017
In the past few decades, the field of acute ischemic stroke (AIS) has experienced significant advances in clinical practice. A core driver of this success has been the utilization of acute stroke imaging with an increasing focus on advanced methods ...

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

open access: yesBiomolecules & 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

open access: yesFrontiers 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.

Collateral donor artery physiology and the influence of a chronic total occlusion on fractional flow reserve [PDF]

open access: yes, 2015
Background— The presence of a concomitant chronic total coronary occlusion (CTO) and a large collateral contribution might alter the fractional flow reserve (FFR) of an interrogated vessel, rendering the FFR unreliable at predicting ischemia should the ...

MRI Visualization of Whole Brain Macro- and Microvascular Remodeling in a Rat Model of Ischemic Stroke: A Pilot Study [PDF]

open access: yes, 2020
Using superparamagnetic iron oxide nanoparticles (SPION) as a single contrast agent, we investigated dual contrast cerebrovascular magnetic resonance imaging (MRI) for simultaneously monitoring macro- and microvasculature and their association with ...

Arteriogenesis versus angiogenesis: similarities and differences [PDF]

open access: yes, 2007
Cardiovascular diseases account for more than half of total mortality before the age of 75 in industrialized countries. To develop therapies promoting the compensatory growth of blood vessels could be superior to palliative surgical surgical ...

The coronary collateral circulation revisited [PDF]

open access: yesNetherlands 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.

The ratio between cerebral blood flow and Tmax predicts the quality of collaterals in acute ischemic stroke [PDF]

open access: yes, 2018
Background In acute ischemic stroke the status of collateral circulation is a critical factor in determining outcome. We propose a less invasive alternative to digital subtraction angiography for evaluating collaterals based on dynamic-susceptibility ...

Leukocytes, Collateral Circulation, and Reperfusion in Ischemic Stroke Patients Treated With Mechanical Thrombectomy.

open access: yesStroke, 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.
