The effect of low concentrations of halothane on the cerebrovascular circulation in young children [PDF]

open access: yesAnaesthesia, 2000
To determine the effect of halothane on cerebral blood flow velocity measured by transcranial Doppler, 23 healthy young children were studied during surgery. Anaesthesia was induced with thiopental, fentanyl and vecuronium, and maintained with halothane in 70% nitrous oxide in oxygen.

The application of susceptibility⁃weighted imaging in cerebral vascular disease

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2022
Susceptibility ⁃weighted imaging (SWI) is a type of MRI developed based on gradient echo sequence (GRE). It is extremely susceptible to paramagnetic substances.

CV-Attention UNet: Attention-based UNet for 3D Cerebrovascular Segmentation of Enhanced TOF-MRA Images [PDF]

open access: yesarXiv, 2023
Due to the lack of automated methods, to diagnose cerebrovascular disease, time-of-flight magnetic resonance angiography (TOF-MRA) is assessed visually, making it time-consuming. The commonly used encoder-decoder architectures for cerebrovascular segmentation utilize redundant features, eventually leading to the extraction of low-level features ...

Chlamydia pneumoniae in atherosclerotic middle cerebral artery [PDF]

open access: yes, 2001
Background and Purpose—Atherosclerotic middle cerebral arteries are frequent sites of thrombosis, leading to stroke. Previous studies have suggested a role for Chlamydia pneumoniae in the pathogenesis of atherosclerosis.

Computer Modeling of Anterior Circulation Stroke: Proof of Concept in Cerebrovascular Occlusion [PDF]

open access: yesFrontiers in Neurology, 2014
Current literature emphasizes the role of the Circle of Willis (CoW) in salvaging ischemic brain tissue but not that of leptomeningeal anastomoses (LA). We developed a computational model of the cerebral circulation to (1) evaluate the roles of the CoW and LA in restoring flow to the superficial compartment of the middle cerebral artery (MCA) territory

Calculus Bovis-Fel Uris-Moschus Pharmacopuncture’s Effect on Regional Cerebral Blood Flow and Mean Arterial Blood Pressure in Rats

open access: yesJournal of Pharmacopuncture, 2013
Objectives: This study was designed to investigate the effects of Calculus Bovis-Fel Uris-Moschus pharmacopuncture (BUM) on the regional cerebral blood flow (rCBF) and the mean arterial blood pressure (MABP) in normal and cerebral ischemic rats and to ...

Relation of post-stroke headachto cerebrovascular pathology and hemodynamics

open access: yesFolia Neuropathologica, 2022
Despite high prevalence of cerebrovascular stroke, headache attributed to ischemic strokes is often undertreated and overlooked. The aim is to detect the relation of a post-stroke headache to cerebrovascular pathology and changes in hemodynamics through ...

An automated multiscale ensemble simulation approach for vascular blood flow [PDF]

open access: yes, 2015
Cerebrovascular diseases such as brain aneurysms are a primary cause of adult disability. The flow dynamics in brain arteries, both during periods of rest and increased activity, are known to be a major factor in the risk of aneurysm formation and rupture. The precise relation is however still an open field of investigation.
