【摘要】：目的探討貴州省黔南布州依族及苗族成人Willis環(huán)解剖變異及分型,為黔南地區(qū)少數(shù)民族腦血管疾病提供對(duì)照。方法本研究為回顧性研究,連續(xù)納入黔南州人民醫(yī)院2011年12月~2017年2月期間CT及MRI檢查正常,并作CTA檢查黔南布依族或苗族成人513名,將檢查數(shù)據(jù)采用西門子signo工作站,行VR、MIP及MPR多模式、多角度觀察Willis環(huán)的發(fā)育情況進(jìn)行分型,分析各種類型的情況。結(jié)果根據(jù)組成動(dòng)脈的發(fā)育情況,將513例正常腦動(dòng)脈Willis環(huán)分為4型,Ⅰ型3.7%(19例);Ⅱ型0.1%(5例);Ⅲ型65.5%(336例),根據(jù)后循環(huán)的發(fā)育情況分為5個(gè)亞型: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),根據(jù)前、后循環(huán)的發(fā)育情況組合將Ⅳ型分為5個(gè)亞型: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)。結(jié)論 CTA是一種無(wú)創(chuàng)、有效的評(píng)價(jià)腦底動(dòng)脈環(huán)類型的方法,利用CTA評(píng)價(jià)黔南地區(qū)少數(shù)民族腦底動(dòng)脈環(huán)可以為其他與腦血管類型有關(guān)疾病提供正常對(duì)照;黔南少數(shù)民族地區(qū)對(duì)稱型Willis環(huán)顯示率較低,以Ⅲ型為主,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，
