Detailed study of arterial variations in circle of Willis among migraine and non migrainous patients in Western Uttar Pradesh

Background: The human brain represents 2% of human body weight. It is supplied by two major arteries, paired internal carotid arteries and vertebral arteries. The arterial circle of Willis forms a polygonal anastomotic channel between two internal carotid artery and two vertebral arteries. The arterial circle is situated at the base of the brain in the interpeduncular fossa. Dr. Thomas Willis who first described the function of arterial anastomosis in 1966. Aim: To study the incidence of arterial variations in circle of willis among migraine patients of Western U.P. Methodology: Present study was conducted in the Department of Anatomy, Santosh Medical College Ghaziabad in collaboration with the Department of Radiodiagnosis, Rama Medical College & Hospital, Ghaziabad and from Dr. O.P Gupta Imaging Centre, Meerut. A total of 132 patients were scanned and 3D TOF sequence has been taken for MRA (BRAIN) examination.3D angiogram was reviewed for variation in brain. Results: The complete circle of Willis was absent among16.7% Migraine patients and 12.2% in non migrainous patients. The anterior communicating artery (A.com.) was absent in 26.7% migrainespatients and Anterior communicating artery were present in 73.3% in migrainous patients
