Selective vulnerability of medial temporal regions to short-term blood pressure variability and cerebral hypoperfusion in older adults

NeuroImage: Reports, 2022
Blood pressure variability is an emerging risk factor for stroke, cognitive impairment, and dementia, possibly through links with cerebral hypoperfusion.

Head Elevation, Cerebral Venous System, and Intracranial Pressure: Review and Hypothesis

Stroke: Vascular and Interventional Neurology, 2023
Background Facilitation of venous outflow from the brain is largely believed to be responsible for the beneficial effect of head elevation on intracranial pressure (ICP). However, the impact on cerebral perfusion pressure can be deleterious. Although the

Comparison of static and dynamic cerebral autoregulation under anesthesia influence in a controlled animal model.

PLoS ONE, 2021
The brain's ability to maintain cerebral blood flow approximately constant despite cerebral perfusion pressure changes is known as cerebral autoregulation (CA) and is governed by vasoconstriction and vasodilation.

Cerebral venous steal equation for intracranial segmental perfusion pressure predicts and quantifies reversible intracranial to extracranial flow diversion

Scientific Reports, 2021
Cerebral perfusion is determined by segmental perfusion pressure for the intracranial compartment (SPP), which is lower than cerebral perfusion pressure (CPP) because of extracranial stenosis. We used the Thevenin model of Starling resistors to represent

Optimal Cerebral Perfusion Pressure: Targeted Treatment for Severe Traumatic Brain Injury

Journal of Neurotrauma, 2020
Identification of individual therapy targets is critical for traumatic brain injury (TBI) patients. Clinical outcomes depend on cerebrovascular autoregulation (CA) impairment.

Targeted Perfusion Therapy in Spinal Cord Trauma. [PDF]

, 2020
We review state-of-the-art monitoring techniques for acute, severe traumatic spinal cord injury (TSCI) to facilitate targeted perfusion of the injured cord rather than applying universal mean arterial pressure targets.

Early cerebral perfusion pressure augmentation with phenylephrine after traumatic brain injury may be neuroprotective in a pediatric swine model* [PDF]

, 2012
Objective: Cerebral perfusion pressureage, and current guidelines recommend maintaining cerebral perfusion pressure between 40 mm Hg–60 mm Hg. Although adult traumatic brain injury studies have observed an increased risk of complications associated with ...
