The collaterome: A novel conceptual framework of systems biology in cerebrovascular disorders

Brain Circulation, 2015
The collaterome is the elaborate neurovascular architecture within the brain that regulates and determines the compensatory ability, response, and outcome of cerebrovascular pathophysiology.

Exploring the effects of resveratrol supplementation on cerebrovascular function in hormonal migraineurs: A pilot study [PDF]

, 2023
Background Past research suggests that hormonal migraineurs may have poorer cerebrovascular function than women who do not suffer from migraine. Resveratrol, a vasoactive phytoestrogen, has been shown to improve cerebrovascular function in several ...

Acute Gravitational Stress Selectively Impairs Dynamic Cerebrovascular Reactivity in the Anterior Circulation Independent of Changes to the Central Respiratory Chemoreflex [PDF]

, 2022
Cerebrovascular reactivity (CVR) to changes in the partial pressure of arterial carbon dioxide (PaCO2) is an important mechanism that maintains CO2 or pH homeostasis in the brain.

Cerebrovascular reactivity to hypercapnia during sevoflurane or desflurane anesthesia in rats [PDF]

Korean Journal of Anesthesiology, 2019
Background Hypercapnia causes dilation of cerebral vessels and increases cerebral blood flow, resulting in increased intracranial pressure. Sevoflurane is reported to preserve cerebrovascular carbon dioxide reactivity.

Cerebral hyperperfusion syndrome after endovascular stent graft reconstruction for postirradiated carotid blowout syndrome: a case report [PDF]

Journal of Neurocritical Care, 2022
Background Cerebral hyperperfusion syndrome (CHS) is a failure of autoregulation after a revascularization procedure. It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report We present a rare case of a patient who

Posterior circulation cerebrovascular syndromes: diagnosis and management [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2016
One in five strokes affects the posterior circulation. Diagnosing posterior circulation stroke can be challenging, as the vascular anatomy can be variable, and because presenting symptoms are often non-specific and fluctuating. Nevertheless, making the correct diagnosis is important, as these strokes have a high chance of recurrence, can be life ...

Melatonin does not attenuate dynamic cardiovascular and cerebrovascular reflex responses to acute hypotension in healthy men [PDF]

Korean Journal of Anesthesiology, 2012
BackgroundMelatonin has been shown to attenuate the reflex sympathetic increases that arise in response to orthostatic challenges. We tested the hypothesis that the attenuated sympathetic increase induced by melatonin premedication may weaken the ...

Risk of perioperative stroke and cerebral autoregulation monitoring: a systematic review

Arquivos de Neuro-Psiquiatria, 2022
Background Perioperative stroke, delirium, and cognitive impairment could be related to management and to variations in blood pressure control, cerebral hypoperfusion and raised blood volume.

Endothelial dysfunction indicators and hemorheological properties in acute ischemic stroke

Анналы клинической и экспериментальной неврологии, 2017
We evaluated endothelial dysfunction and hemorheological indicatorsin acute ischemic stroke. The hemorheological indicators(blood viscosity, plasma viscosity, hematocrit, erythrocyte aggregationand deformability, fibrinogen concentration) were ...

Cerebrovascular Reservoir and Arterial Transit Time Changes Assessed by Acetazolamide-Challenged Multi-Phase Arterial Spin Labeling Perfusion MRI in Chronic Cerebrovascular Steno-Occlusive Disease

대한영상의학회지, 2021
Purpose To explore cerebrovascular reservoir (CVR) and arterial transit time (ATT) changes using acetazolamide-challenged multi-phase arterial spin labeling (MP-ASL) perfusion-weighted MRI in chronic cerebrovascular steno-occlusive disease.
