BACKGROUND AND PURPOSE: It has been shown that the brain of a preterm infant
develops differently from that of a term infant, but little is known about the neonatal …

Background: Previous studies have shown a disrupted development of cerebral blood
vessels at term-equivalent age in prematurely born infants. Objective: To assess the …

Background: The aim of this study was to evaluate the frequency of circle of Willis (COW)
variations and the measurements of the COW vessel diameters in the Turkish population …

Background: The main scope of this paper is to investigate the prevalence of the anatomical
variants of the circle of Willis (CoW) in the Romanian population through magnetic …

Variations of the circle of Willis (CW) influence blood supply to the brain and adjacent
structures in adults. We examined the formation of the CW in 20 human embryo samples at …

Background: Cerebrovascular diseases such as stroke, aneurysms and arterio-venous
malformations are very much prevalent in our country. Circle of Willis, as an anastomotic …

To establish the usual pattern of flow in the circle of Willis in newborns, the authors scanned
53 healthy full-term infants within 3 days of birth with color Doppler imaging. All …

Because the circle of Willis (CoW) supplies blood to the brain in case of occlusion of one of
the cerebral arteries, identification of any change in its classical shape could be useful in the …

Objective: The objective of the present work was to study the anatomical variations of the
circle of Willis as regard its component vessels and their average diameters in a sample of …

Background and Purpose. There is a wide variation in the anatomy of the CW in different
individuals and population groups. The purpose of this study was to determine the …
