Anatomical 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...

Variations of the Circle of Willis in 100 Cadavers in Kerman Province

Background & Aims: The relationship between variations of Willis circle and some cerebrovascular diseases has been shown in previous studies. A few studies have been conducted in Iran on these variations. Methods: This study was performed on 100 recently deceased Iranians due to car accidents who had been referred to Kerman Forensic Medicine Center for autopsy. The length and diameter of cerebr...

VARIATIONS 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...
