Accurate knowledge of brain anatomy is essential in the formation and practice of Neuroanatomy of students studying neurology and neurosurgery. Currently, the study of human anatomy has changed its approach, from being a descriptive anatomy and from dissection to one with clinical application. The present study was carried out with the objective of knowing the morphological variants that the cerebral arterial circle (polygon ofWillis) has in brains counted in the amphitheater at the Universidad Privada del Valle. For this study, 19 brains, extracted form corpses, were injected with modified acetic red silicone in the arteries that supply the brain. Once the silicone was solidified, we observed the path of the blood vessels; measurements of the external diameter of each artery or blood vessel were taken with the help of a digital caliper. The results found reveal that in 68,42% the external diameter of the cerebral arteries was greater than 1,00 mm and in the communicating cerebral arteries the size was greater than 0,5 mm; in both cases these are considered a classic type. In 31,58% it was found anatomical variants of the hypoplasia type, the only anomaly found, with unitary and hypoplasia predominating on the left side. This knowledge helps to predict those who have a circle normal or classic arterial damage have cerebrovascular damage and their recovery is better in relation to those who have hypoplasia or some anatomical variant. The prognosis is that it Will have higher complications compared to the classic.
