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

open access: yesJournal 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

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

open access: yesKorean 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.

Quantitative Analysis of Brain CT Perfusion in Healthy Beagle Dogs: A Pilot Study

open access: yesVeterinary Sciences, 2023
Brain computed tomography (CT) perfusion is a technique that allows for the fast evaluation of cerebral hemodynamics. However, quantitative studies of brain CT perfusion in veterinary medicine are lacking. The purpose of this study was to investigate the

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

open access: yesKorean 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 ...

Wavelet Autoregulation Monitoring Identifies Blood Pressures Associated With Brain Injury in Neonatal Hypoxic-Ischemic Encephalopathy

open access: yesFrontiers in Neurology, 2021
Dysfunctional cerebrovascular autoregulation may contribute to neurologic injury in neonatal hypoxic-ischemic encephalopathy (HIE). Identifying the optimal mean arterial blood pressure (MAPopt) that best supports autoregulation could help identify ...

Endothelial dysfunction indicators and hemorheological properties in acute ischemic stroke

open access: yesАнналы 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 ...

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

open access: yesArquivos 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.
