Abstract

Introduction: Circle of Willis, is an arterial circle, furnishing arterial supply to most of the brain and meninges. However, its formation and a complete arterial circle, differs among individuals.

Objectives: In the present study, an attempt has been made to identify those variations and to segregate them into anterior and posterior circulation.

Materials and method: Thirty-two cadaveric brains were used for the study.

Results: The results show that the variations of the anterior circulation exceeded those observed in the posterior circulation.

Conclusions: These variations would add on to the previous findings and thus help the neurosurgeons while operating this region.
