Dynamic Cerebral Autoregulation Post Endovascular Thrombectomy in Acute Ischemic Stroke

Brain Sciences, 2020
The development of the endovascular thrombectomy (EVT) technique has revolutionized acute stroke management for patients with large vessel occlusions (LVOs). The impact of successful recanalization using an EVT on autoregulatory profiles is unknown.

Individualized perfusion targets in hypoxic ischemic brain injury after cardiac arrest

Critical Care, 2017
Secondary injury is a major determinant of outcome in hypoxic ischemic brain injury (HIBI) after cardiac arrest and may be mitigated by optimizing cerebral oxygen delivery (CDO2).

Association between impaired dynamic cerebral autoregulation and BBB disruption in reversible cerebral vasoconstriction syndrome

The Journal of Headache and Pain, 2023
Background Half of the sufferers of reversible cerebral vasoconstriction syndrome (RCVS) exhibit imaging-proven blood-brain barrier disruption. The pathogenesis of blood-brain barrier disruption in RCVS remains unclear and mechanism-specific intervention

Cerebral Blood Flow Autoregulation in Offspring From Experimentally Preeclamptic Rats and the Effect of Age

Frontiers in Physiology, 2022
Preeclampsia is a hypertensive disorder of pregnancy that causes significant, long term cardiovascular effects for both the mother and offspring. A previous study demonstrated that middle cerebral arteries in offspring from an experimental rat model of ...

Cerebellar and Cerebral Autoregulation in Migraine [PDF]

Stroke, 2012
Background and Purpose— Silent ischemic brain lesions frequently occur in migraine with aura and are most often located in cerebellar border zones. This may imply an impairment of cerebellar blood flow autoregulation. This study investigated the characteristics of interictal cerebellar autoregulation in migraine with and ...

Dynamic cerebral autoregulation is acutely impaired during maximal apnoea in trained divers.

PLoS ONE, 2014
AimsTo examine whether dynamic cerebral autoregulation is acutely impaired during maximal voluntary apnoea in trained divers.MethodsMean arterial pressure (MAP), cerebral blood flow-velocity (CBFV) and end-tidal partial pressures of O2 and CO2 (PETO2 and

Impact of impaired cerebral blood flow autoregulation on cognitive impairment

Frontiers in Aging, 2022
Although the causes of cognitive impairment are multifactorial, emerging evidence indicates that cerebrovascular dysfunction plays an essential role in dementia.

Cerebral autoregulation in Alzheimer's disease [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2011
Cerebral autoregulation aims to stabilize blood flow to the brain during variations in perfusion pressure, thus protecting the brain against the risks of low or high systemic blood pressure. This vital mechanism is severely impaired in the transgenic mouse model of Alzheimer's disease (AD) that abundantly produces amyloid-β peptide

Cerebral autoregulation monitoring in neonates and infants after cardiac surgery with cardiopulmonary bypass - comparison of single ventricle and biventricular physiology

Frontiers in Pediatrics
IntroductionCardiopulmonary bypass surgery can lead to impaired cerebral autoregulation with the risk for ischemia, hemorrhage and delirium. In particular, infants with single ventricle physiology have altered hemodynamics with persistent veno-arterial ...

Correlation of rheoencephalography and laser Doppler flow: a rat study

Journal of Electrical Bioimpedance, 2016
Measuring brain electrical impedance (rheoencephalography) is a potential technique for noninvasive, continuous neuro-monitoring of cerebral blood flow autoregulation in humans.
