Abstract Objective: To analyze the relationship between classification of Willis circle (CoW) and aneurysm of anterior communicating artery (ACoA) based on cranial computer tomography angiography (CTA). Methods: A total of 1 184 inpatients who underwent both digital subtraction angiography (DSA) and cerebral CTA in the First Affiliated Hospital of Wenzhou Medical University from September 2006 to January 2016 were retrospectively analyzed. Patients with ACoA aneurysms were included in the ACoA aneurysm group (n=630), and patients without intracranial aneurysms were included in the control group (n=554). CoW is divided into anterior circulation and posterior circulation, which are further divided into 10 anatomical subtypes: a, b, c, d, e, f, g, h, i, j. All patients in the two groups were counted the number of each type of anterior and posterior circulation according to anatomical classification. The incidence of ACoA aneurysm was compared among different anatomical types. Results: The incidence of subtype g of anterior circulation in the control group was significantly higher than that in the ACoA aneurysm group. The incidence of h-type anterior circulation in ACoA aneurysm group was significantly higher than that in the control group. The incidence of type a, c and d posterior circulation in the control group was significantly higher than that in the ACoA aneurysm group. The incidence of type g, h and i posterior circulation in ACoA aneurysm group was significantly higher than that in the control group. Conclusion: The occurrence of ACoA aneurysm is related to the anatomical variation of CoW.
