Posterior arterial circle of Willis anatomic variations and coronary artery dominance: is there a correlation?

open access: yesAutopsy and Case Reports, 2011
Anatomic variations and anomalies in the arteries from the circle of Willis or the heart are common, sometimes even more common than the classic morphology.

Particularities of the imagistic diagnosis of the cervical-cerebral arteries dissection. Flow-splitter dissection [PDF]

open access: yesRomanian Journal of Neurology, 2010
Background: Dissection of the cervical-cerebral arteries is an important cause of stroke in all age groups, specifically in younger population. Dissection of the cervical-cerebral arteries is produced by rupture of the intima and media layers, leading to

Triptans and CGRP blockade - impact on the cranial vasculature [PDF]

open access: yes, 2017
The trigeminovascular system plays a key role in the pathophysiology of migraine. The activation of the trigeminovascular system causes release of various neurotransmitters and neuropeptides, including serotonin and calcitonin gene-related peptide ...

Asymmetries of total arterial supply of cerebral hemispheres do not exist

open access: yesHeliyon, 2019
Background: Total blood supply to an organ, or its part, is proportional to its function. The aim of this project was to investigate whether there is a lateralisation of total functions of cerebral hemispheres by determining differences in the arterial ...

MRI and clinical characteristics of suspected cerebrovascular accident in nine cats [PDF]

open access: yes, 2017
Objectives Cerebrovascular accidents (CVAs) are infrequently reported in cats. To date, clinical characteristics, including lesion localisation and MRI findings, have only been reported in two cats.

Expressional changes in cerebrovascular receptors after experimental transient forebrain ischemia.

open access: yesPLoS ONE, 2012
BackgroundGlobal ischemic stroke is one of the most prominent consequences of cardiac arrest, since the diminished blood flow to the brain results in cell damage and sometimes permanently impaired neurological function.

The Role of Mitochondrial Biogenesis in Ischemic Stroke

open access: yesJournal of Integrative Neuroscience, 2023
Ischaemic stroke is a sudden neurological disorder caused by localised cerebral ischaemia and persistent cerebral infarction. Occlusion of large arteries due to atherothrombosis, cerebral embolism (i.e., embolic infarction), no thrombotic occlusion in ...
