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

The Analysis of Indices of Cerebral Blood Circulation in Women-smokers [PDF]

open access: yes, 2017
The results of rheoencephalography of female smokers 17–21 years old and control group were studied and analyzed. The aim of this work was to explain and analyze physiological features of smoking effect on functional changes of regional hemodynamics in ...

Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]

open access: yesScientific Reports, 9: 3779, 2019, 2019
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

Attempt to establish an experimental animal model of moyamoya disease using immuno-embolic material--histological changes of the arterial wall resulting from immunological reaction in cats. [PDF]

open access: yes, 2003
In this study, we investigated the relationship between intimal thickening of the internal carotid artery (ICA) and immunological reaction, and between occlusion of the ICA and development of basal collateral vessels in moyamoya disease.

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.
