Cerebral and Sinus Vein Thrombosis [PDF]

open access: yesCirculation, 2014
A blood clot in the veins that drain the blood from the brain is called a sinus or cerebral vein thrombosis. It is an uncommon type of clot, affecting about 1500 people in the United States per year. Normally, blood is transported through arteries into the brain, where it delivers oxygen and nutrients. Once the blood has done its job, it collects into

Aphasic Syndromes in Cerebral Venous and Dural Sinuses Thrombosis—A Review of the Literature

open access: yesLife, 2022
Aphasia is an acquired central disorder of language that affects a person’s ability to understand and/or produce spoken and written language, caused by lesions situated usually in the dominant (left) cerebral hemisphere.

Monro-Kellie 2.0: The dynamic vascular and venous pathophysiological components of intracranial pressure [PDF]

open access: yes, 2016
For 200 years, the ‘closed box’ analogy of intracranial pressure (ICP) has underpinned neurosurgery and neuro-critical care. Cushing conceptualised the Monro-Kellie doctrine stating that a change in blood, brain or CSF volume resulted in reciprocal ...

Cerebral Vasculature Influences Blast-Induced Biomechanical Responses of Human Brain Tissue

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Multiple finite-element (FE) models to predict the biomechanical responses in the human brain resulting from the interaction with blast waves have established the importance of including the brain-surface convolutions, the major cerebral veins, and using

Appearance of the canine meninges in subtraction magnetic resonance images [PDF]

open access: yes, 2014
The canine meninges are not visible as discrete structures in noncontrast magnetic resonance (MR) images, and are incompletely visualized in T1‐weighted, postgadolinium images, reportedly appearing as short, thin curvilinear segments with minimal ...

Using a novel source-localized phase regressor technique for evaluation of the vascular contribution to semantic category area localization in BOLD fMRI. [PDF]

open access: yes, 2015
Numerous studies have shown that gradient-echo blood oxygen level dependent (BOLD) fMRI is biased toward large draining veins. However, the impact of this large vein bias on the localization and characterization of semantic category areas has not been ...

Convective infux/glymphatic system: tracers injected into the CSF enter and leave the brain along separate periarterial basement membrane pathways [PDF]

open access: yes, 2018
Tracers injected into CSF pass into the brain alongside arteries and out again. This has been recently termed the "glymphatic system" that proposes tracers enter the brain along periarterial "spaces" and leave the brain along the walls of veins.

Cerebral venous hemodynamic abnormalities in episodic and chronic migraine [PDF]

open access: yes, 2016
Alterations of cerebral venous drainage have been demonstrated in chronic migraine (CM), suggesting that cerebral venous hemodynamic abnormalities (CVHAs) play a role in this condition.

Evaluation of Venous Structures that Are Involved in Transsylvian Approach Using 3D Rotational Venography

open access: yesNeurologia Medico-Chirurgica, 2023
In the transsylvian (TS) approach, as characterized by clipping surgery, the presurgical visualization of the superficial middle cerebral vein (SMCV) can help change the surgical approach to ensure safe microsurgery.

Papilledema and venous stasis in patients with cerebral venous and sinus thrombosis

open access: yesBMC Neurology, 2023
Background Cerebral venous and sinus thrombosis (CVST) can cause increased intracranial pressure, often leading to papilledema. In this study, we investigated the association between papilledema and venous stasis on susceptibility weighted imaging (SWI ...
