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.

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

Posterior circulation cerebrovascular syndromes: diagnosis and management [PDF]

open access: yesJournal 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]

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 ...

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 ...

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

open access: yes대한영상의학회지, 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.

Preliminary study on internal carotid artery perfusion imaging and clinical application based on digital subtraction angiography

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2022
Background DSA is an irreplaceable diagnostic method for cerebral vascular disease. It is sensitive to intracranial macrovascular disease, but not to distal blood perfusion. In order to quantitatively assess the perfusion area of the feeding artery, this

Edaravone attenuates sustained pial arteriolar vasoconstriction independently of endothelial function after unclamping of the abdominal aorta in rabbits [PDF]

open access: yesKorean Journal of Anesthesiology, 2021
Background Cerebral blood flow (CBF) has direct effects on neuronal function and neurocognitive disorders. Oxidative stress from abdominal aortic surgery is important in the pathophysiology of CBF impairment.
