The variations of the anterior part of the circle of Will’s may lead to some clinical conditions like Cerebrovascular diseases such as stroke, aneurysms, internal carotid artery occlusion and migraine. The present study was aimed to find out the incidence of the variations of the anterior part of the circle of Willi’s in the Telangana Population. Materials and Methods: A total of 40 adult brains (30 male and 10 female) were obtained from the dissection and the anterior part of the circle of Willi’s were studied and the observed variations of the middle cerebral artery, the anterior cerebral artery and anterior communicating artery were recorded and photographed. Results: Variations were observed in 27.5% specimens in which 7.5% specimens had double anterior communicating arteries, 7.5% specimens shown union and separation of anterior cerebral arteries, 2.5% specimens had an aneurysm of the anterior cerebral artery and anterior communicating artery, 2.5% specimen shown triple anterior cerebral artery, 5% specimens had the hypoplasia of anterior cerebral artery and 2.5% specimens had duplication of middle cerebral artery. Conclusion: Knowledge of the anatomical variations of the anterior part of the circle of Willi’s is of great value to the neurosurgeons while dealing with cerebrovascular stroke, aneurysms of the anterior cerebral artery, anterior communicating artery, and middle cerebral artery.
