VARIATIONS IN CIRCLE OF WILLIS AND THEIR CLINICAL IMPLICATIONS: A COMPREHENSIVE ANATOMICAL STUDY

Background: The Circle of Willis (CoW) is a crucial arterial anastomotic network at the base of the brain that ensures collateral circulation. However, anatomical variations are common and may influence cerebrovascular diseases. Objective: To study anatomical variations of the Circle of Willis and evaluate their clinical implications. Methods: A descriptive study using cadaveric specimens and radiological imaging was conducted. Variations were classified based on completeness and arterial anomalies. Results: A complete Circle of Willis was observed in fewer cases, while most showed variations such as hypoplasia and aplasia. Conclusion: Variations are common and clinically significant in cerebrovascular disorders.
