Abstract The present study evaluated the calibers and anatomic configurations based on the Magnetic Resonance analysis (MRA), assaying the cerebral vascular territories and sex-linked variations. A ...

When a watershed infarct is seen unilaterally, this is usually due to hemodynamic narrowing of a proximal artery (in this case, the carotid artery) without intact collateral vessels (e.g., an ...

A fractional-order model is proposed to describe the dynamic behaviors of the velocity of blood flow in cerebral aneurysm at the circle of Willis. The fractional-order derivative is used to model the ...

An incomplete Circle of Willis, defined by aplasia of any arterial segment, was present in 875 (77.7%) patients. The most common variation found was aplasia of the right posterior communicating artery ...

Bruce Willis' wife Emma Heming Willis shared an emotional post to mark their 17th anniversary. She opened up about her "unconditional love" for the actor as he battles dementia.

Any change in flow in the common carotid artery resulting from obstruction of the other cerebral vessels entering the circle of Willis was assumed to be directed to the internal carotid artery.

Velocity of blood flow is quite high through the anterior segment of the circle of Willis and through the anterior and middle cerebral arteries. brain-stem and posterior cerebral irrigation, by ...

Background: The circle of Willis (CoW) is the most common location for aneurysms to form in humans. Although the major cell types of the intracranial vasculature are well known, the heterogeneity and ...
