Heritability of circle of Willis variations in families with intracranial aneurysms. [PDF]

PLoS ONE, 2018
Intracranial aneurysms more often occur in the same arterial territory within families. Several aneurysm locations are associated with specific circle of Willis variations.

Distribution of variations in anatomy of the circle of Willis: results of a cadaveric study of the Malawian population and review of literature

The Pan African Medical Journal, 2021
INTRODUCTION: The circle of Willis is an anatomical structure of clinical importance particularly in the evaluation of neurovascular diseases. Individuals show considerable variations in the anatomical configuration of the circle of Willis.

Function of Circle of Willis [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2014
Nearly 400 years ago, Thomas Willis described the arterial ring at the base of the brain (the circle of Willis, CW) and recognized it as a compensatory system in the case of arterial occlusion. This theory is still accepted. We present several arguments that via negativa should discard the compensatory theory. (1) Current theory is anthropocentric; it

Presence of anatomical variations of the circle of Willis in patients undergoing surgical treatment for ruptured intracranial aneurysms [PDF]

Vojnosanitetski Pregled, 2009
Background/Aim. The presence of aneurysmal changes on the brain blood vessels has been subject to numerous research. This study investigated the relation between ruptured aneurysms and anatomical configuration of the Circle of Willis, with the purpose to

Normal Variants of the Circle of Willis in patients undergoing CT Angiography

Journal of College of Medical Sciences-Nepal, 2017
Background & Objectives: The Circle of Willis represents the important anastomotic cerebral vessels at the base of the brain. Variation in the Circle of Willis is common. A complete or normal Circle of Willis varies widely in the literature.

Anatomical variants of circle of Willis [PDF]

Praxis Medica, 2020
Introduction: The circle of Willis is the major source of collateral blood flow between the carotid and vertebrobasilar system. Its potential depends on the presence and size of arteries that vary greatly among normal individuals and therefore their ...

Segmentation of Circle of Willis from 7T TOF-MRI data and immersive exploration using VR

Current Directions in Biomedical Engineering, 2022
7T TOF MRI scans provide high resolution images of intracranial vasculature. When segmented, the Circle of Willis is detailed and thus opens up new possibilities, in research but also in education.
