Association between Circle of Willis Configuration and Rupture of Cerebral Aneurysms
Medicina (Lithuania), 2019 Background and Objectives: Intracranial hemorrhage caused by the rupture of brain aneurysms occurs in almost 10 per 100,000 people whereas the incidence of such aneurysms is significantly higher, accounting for 4−9%.

Computation of Hemodynamics in the Circle of Willis [PDF]
Stroke, 2007 Background and Purpose— Wall shear stress (WSS) and pressure are important factors in the development of cerebral aneurysms. We aimed to develop a computational fluid dynamics simulator for flow in the complete circle of Willis to study the impact of variations in vessel radii and bifurcation angles ...

Pulsatility analysis of the circle of Willis
Aging BrainPurpose: To evaluate the phenomenological significance of cerebral blood pulsatility imaging in aging research. Methods: N = 38 subjects from 20 to 72 years of age (24 females) were imaged with ultrafast MRI with a sampling rate of 100 ms and ...

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.

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.

Analysis of the symmetric configuration of the circle of Willis in a series of autopsied corpses [PDF]
Vojnosanitetski Pregled, 2015 Introduction. The forming of the blood vessels network configuration at the base of the brain and interconnecting of blood vessels during the embryogenesis is directly related to the phylogenetic development of the brain and brain structures.
