【摘要】：目的探讨贵州省黔南布州依族及苗族成人Willis环解剖变异及分型,为黔南地区少数民族脑血管疾病提供对照。方法本研究为回顾性研究,连续纳入黔南州人民医院2011年12月~2017年2月期间CT及MRI检查正常,并作CTA检查黔南布依族或苗族成人513名,将检查数据采用西门子signo工作站,行VR、MIP及MPR多模式、多角度观察Willis环的发育情况进行分型,分析各种类型的情况。结果根据组成动脉的发育情况,将513例正常脑动脉Willis环分为4型,Ⅰ型3.7%(19例);Ⅱ型0.1%(5例);Ⅲ型65.5%(336例),根据后循环的发育情况分为5个亚型:Ⅲa,18.9%(97例);Ⅲb,32.2%(165例);Ⅲc,2.5%(13例);Ⅲd,4.5%(23例);Ⅲe,7.4%(38例);Ⅳ型29.8%(153例),根据前、后循环的发育情况组合将Ⅳ型分为5个亚型:Ⅳa,21%(108例);Ⅳb型,1.2%(6例);Ⅳc,1.6%(8例);Ⅳd型,1.9%(10例);Ⅳe型,4.1%(21例)。结论 CTA是一种无创、有效的评价脑底动脉环类型的方法,利用CTA评价黔南地区少数民族脑底动脉环可以为其他与脑血管类型有关疾病提供正常对照;黔南少数民族地区对称型Willis环显示率较低,以Ⅲ型为主,Ⅳ型次之。
[Abstract]:Objective to study the anatomical variation and type of Willis ring in the adults of Buzhou nationality and Miao nationality in Guizhou province, and to provide a control group for cerebrovascular diseases of minority nationalities in southern Guizhou. Methods for retrospective study, CT and MRI examinations were performed in Qiannan people's Hospital from December 2011 to February 2017. 513 adults of Buyi or Miao nationality in Qiannan were examined by CTA. Siemens signo workstation was used to test the data. The development of Willis ring was observed from different angles and all kinds of patterns were analyzed. Results according to the development of the constituent arteries, the Willis rings of 513 normal cerebral arteries were divided into 4 types. There were 19 cases of type 鈪，
