完全性大动脉转位多排螺旋CT临床价值

目的探讨多排螺旋CT(MSCT)诊断完全性大动脉转位(complete transposition of the great arteries,CTGA)的临床价值。资料与方法回顾性分析2006年1月至2010年7月46例接受CT血管造影(CTA)检查的完全性大动脉转位(TGA)患者的影像资料。均行MSCT扫描,其中对于<6岁、不能合作或心功能不全的患儿,检查前由麻醉师进行麻醉。结果 MSCT诊断TGA S,D,A型30例,S,D,D型12例,S,D,L型3例,I,L,A型1例,合并肺动脉瓣及瓣下流出道狭窄28例,室间隔完整7例。左侧三房心1例,永存左上腔静脉4例,下腔静脉肝段缺如1例。房间隔缺损(ASD)12例,动脉导管未闭(PDA)10例,卵圆孔未闭(FO)2例,主动脉右弓右降3例。室间隔增厚1例。左侧并列心耳3例,右主支气管重度狭窄2例。28例行手术矫治。结论 MSCT可准确诊断TGA心内及心外异常结构,为外科手术提供直观信息,为手术方式的选择提供依据。

Clinical Value of MSCT for Complete Transposition of Great Arteries

Objective To investigate the value of multi-slice spiral computed tomography(MSCT) in the diagnosis of complete transposition of great arteries(TGA).Materials and Methods Forty six patients with TGA(age from 1 day to 25 years old,27 males and 19 females) were performed MSCT examination.For the children under 6 years old,the patients with cardiac insufficiency,or not co-operating patients,they were anesthetized by anesthetist in advance.Results Among 46 cases of TGA,30 cases were SDA type,12 were SDD type,3 ...
