Doppler colour flow imaging of fetal intracerebral arteries relative to fetal behavioural states in normal pregnancy [PDF]

open access: yes, 1994
In 14 normally developing term fetuses, the relationship between the blood flow velocity waveforms at cerebral arterial level (internal carotid artery, anterior, middle and posterior cerebral artery) and fetal behavioural states was studied using Doppler

Macrophage depletion reduced brain injury following middle cerebral artery occlusion in mice

open access: yesJournal of Neuroinflammation, 2016
Macrophages are involved in demyelination in many brain diseases. However, the role of macrophages in the recovery phase of the ischemic brain is unknown.

Multiplanar computed tomography reconstruction to aid in recognition of the middle cerebral artery “Dot” sign: The sagittal string sign

open access: yesSAGE Open Medical Case Reports, 2017
While non-contrast head computed tomography is effective in detecting blood, it is not sensitive in diagnosing hyperacute ischemic stroke. One neuroradiologic marker for early thromboembolic occlusion of the distal middle cerebral artery is the middle ...

Function of BID - a molecule of the bcl-2 family - in ischemic cell death in the brain [PDF]

open access: yes, 2002
Mitochondrial mechanisms, particularly the release of cytochrome c, play a role in the death of nerve and glial cells in cerebral ischemia. We have currently investigated whether BID, a proapoptotic molecule of the bcl-2 family and promoter of the ...

Acute middle cerebral artery stroke in a patient with a patent middle cerebral artery [PDF]

open access: yesNeurology Clinical Practice, 2019
Knowledge of cerebrovascular anatomical variants is vital for clinicians working with patients presenting with signs and symptoms of cerebral infarction, particularly in the era of endovascular clot retrieval.We provide an overview of a cerebrovascular anatomical variation and detail a patient presenting with cerebral infarction secondary to occlusion ...

The transient intraluminal filament middle cerebral artery occlusion model as a model of endovascular thrombectomy in stroke

open access: yesJournal of Cerebral Blood Flow and Metabolism, 2015
The clinical relevance of the transient intraluminal filament model of middle cerebral artery occlusion (tMCAO) has been questioned due to distinct cerebral blood flow profiles upon reperfusion between tMCAO (abrupt reperfusion) and alteplase treatment ...

Transcranial doppler in sickle cell anaemia: evaluation of brain blood flow parameters in children of Aracaju, Northeast - Brazil Doppler transcraniano em portadores de anemia falciforme: estudo dos parâmetros de fluxo sangüíneo cerebral em crianças de Aracaju, Sergipe

open access: yesArquivos de Neuro-Psiquiatria, 2008
BACKGROUND: Environmental factors interfere on sickle cell anaemia (SCA). Transcanial Doppler (TCD) is important to evaluate cerebrovascular disease. OBJECTIVE: To evaluate brain haemodynamic profile of children with SCA in Sergipe.

Bilateral middle cerebral artery occlusions: Case report detailing successful treatment with timely mechanical thrombectomy

open access: yesRadiology Case Reports, 2020
Bilateral middle cerebral artery occlusion is a very rare and dangerous pathology, accounting for less than 1% of stroke presentations. Unless treated, the natural course of the disease leads to coma or death and thus is extremely important to be ...

Late Spontaneous Recanalization of Chronic Middle Cerebral Artery Occlusion [PDF]

open access: yesNeurointervention, 2012
Early spontaneous recanalization of the middle cerebral artery in acute ischemic phase artery is not uncommon, whereas the late spontaneous recanalization of chronic occluded artery is a very rare phenomenon and exact incidence and the timing of this ...

Fractal Rigidity in Migraine [PDF]

open access: yes, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...
