摘要: 目的探讨脑血管缺血性病变患者大脑动脉环(Willis环)的发育及变异情况。方法分析100例脑血管病变患者3DTOP MRA图像,统计各个动脉的变异情况及发生率,并与100例健康体检人群的3DTOP MRA图像对照。结果两组Wills环存在很大的变异。病变组与对照组Wllis环发育完整率分别为13%、25%,差异有统计学意义(P<0.05)。结论Willis环发育不完整与脑血管疾病的发生密切相关。

Abstract: Objective  To investigate the development and variation of cerebral artery ring (Willis ring) in patients with cerebral vascular disease. Methods  MRA 3DTOP images of 100 patients with cerebral vascular disease were analyzed, and the variation and incidence of each artery were  analyzed and compared with the MRA 3DTOP images of 100 healthy people. Results  There was a large variation in Willis ring between two groups. Willis ring development complete rates of hospitalized patients and healthy checkup people were 13% and 25%, respectively. There was statistically significant difference between two groups (P<0.05). Conclusion  The incompleteness of Willis ring is closely related to the occurrence of cerebrovascular disease.
