The study results show that female male ratio was 1 the number of patients with only one aneurysm accounted for Saccular aneurysm was more common than lozenge-shaped aneurysm the rate of aneurysm ruptures was the bulge was mainly distributed in the carotid artery . The very small bulge less than 3mm and the small bulge 3-7mm were most common and accounted for and respectively. The variations of the circle of Willis were very diverse and complex including 13 forms four of which were the circle of Willis anterior part variants and nine transformations were the circle of Willis posterior variants. Abnormalities aplasia hypoplasia of the anterior communicating arterial were and abnormalities of the posterior communicating arterial were . The paper concludes that the abnormal anatomical variations in the circle of Willis can facilitate the early diagnosis and treatment of cerebral aneurysm disease.
