目的探讨产前超声观测胎儿主动脉瓣下圆锥连接对诊断胎儿完全型大动脉转位的临床价值.方法回顾分析22例经引产后尸检证实的完全型大动脉转位胎儿的超声心动图资料,总结其异常声像图特点.结果 22例中二维超声心动图均显示主动脉瓣下圆锥连接声像图特征,其中18例在左室长轴观显示两条大动脉前后平行走行,17例心底短轴观显示右室流出道包绕主动脉根部形态消失,9例显示室间隔完整,13例合并室间隔缺损,2例合并左室流出道狭窄.22例中20例主动脉与肺动脉呈右前左后排列,2例呈正前正后排列.结论产前超声观测主动脉瓣下圆锥连接对诊断胎儿完全型大动脉转位具有重要临床价值.

Objective To investigate the value of prenatal ultrasound observation of subaortic conical connection in the diagnosis of complete transposition of great arteries(TGA).Methods Echocardiography findings of 22 cases with complete TGA confirmed by autopsy were retrospectively analyzed and summarized.Results All cases were shown subaortic conical connection on two-dimensional echocardiography,the two great arteries were parallel in 18 cases on left ventricular long-axis view,the character of normal right ventricular outflow tract surrounding the aortic root disappeared in 17 cases.There were 13 cases with ventricular septal defect and 2 cases with left ventricular outflow tract obstruction.Aorta and pulmonary artery were shown in right anterior and left posterior position among 20 cases,and in anterior and posterior position in 2 cases.Conclusions Prenatal ultrasound observation of subaortic conical connection is of great value in the diagnosis of complete TGA.
