[Thrombolysis of the middle cerebral artery]

Der Radiologe, 2009
Intravenous thrombolysis (IVT) is the evidence-based treatment of acute ischemic stroke in the first 3 h after symptom onset (IVT 3-4.5 h: off-label use with informed consent of the patient). However, intra-arterial thrombolysis (IAT) results in higher recanalization rates of the middle cerebral artery compared to IVT.

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

, 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

Protein kinase C inhibition attenuates vascular ET_B receptor upregulation and decreases brain damage after cerebral ischemia in rat

BMC Neuroscience, 2007
Background Protein kinase C (PKC) is known to be involved in the pathophysiology of experimental cerebral ischemia. We have previously shown that after transient middle cerebral artery occlusion, there is an upregulation of endothelin receptors in the ...

Excision of a Large Complex Left Middle Cerebral Artery Aneurysm With a Middle Cerebral Artery—Middle Cerebral Artery and Superficial Temporal Artery—Middle Cerebral Artery Bypass: 2-Dimensional Operative Video [PDF]

Operative Neurosurgery, 2020
Abstract Revascularization techniques for microsurgical manage-ment of middle cerebral artery (MCA) bifurcation aneurysms are often necessary for treatment of fusiform or giant aneurysms. Augmentation of the standard pterional approach to include an extended orbitozygomatic or modified orbitozygomatic approach provides a wider and more ...

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

SAGE 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 ...

Magnetic resonance investigation into the mechanisms involved in the development of high-altitude cerebral edema [PDF]

, 2017
Rapid ascent to high altitude commonly results in acute mountain sickness, and on occasion potentially fatal high-altitude cerebral edema. The exact pathophysiological mechanisms behind these syndromes remain to be determined.

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

, 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]

Neurology 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 ...

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

Arquivos 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.
