Anatomical Variations of the Circulus Arteriosus in Cadaveric Human Brains
Objective. Circulus arteriosus/circle of Willis (CW) is a polygonal anastomotic channel at the base of the brain which unites the internal carotid and vertebrobasilar system. It maintains the steady and constant supply to the brain. The variations of CW are seen often. The Aim of the present work is to find out the percentage of normal pattern of CW, and the frequency of variations of the CW an...
متن کاملAnatomical Variations of Circle of Willis in 57 Human Brains
Purpose: The circle of willis is responsible for blood supply of brain, which may suffer from anatomical variations. These disturbances can lead to aneurysm or even arterial rupture. The purpose of this study was to evaluate the anatomical structure of the cerebral arteries forming the circle of willis in adult cadavers. Also, cerebral versus non- cerebral versus non-cerebral arterial walls wer...
متن کاملVARIATIONS IN THE CIRCULUS ARTERIOSUS OF WILLIS: AUTOPSY FINDINDS IN 101 HUMAN CADAV ERS
In order to evaluate the microvascular anatomy and the interconnections, 101 fixed brains from human cadavers with a mean age of 41.3 years were subjected to objective scrutiny. Symmetry was visualized with an unaided eye and measurements made under microscopic magnification technique using a micrometer. Classic symmetry was observed in only 19 of the specimens, whereas the rest of the 82...

متن کاملAnomalous formation of the circulus arteriosus and its clinico-anatomical significance.
Circulus arteriosus (Circle of Willis) is an anastomotic ring which unites the internal carotid and vertebrobasilar systems. It slows down the blood before it reaches the brain and helps in collateral circulation. Anatomic study reveals the variation in the pattern and calibre of vessels which make up the circulus arteriosus. The greatest variation in calibre occurs in the posterior communicati...
