心脏三节段法在产前超声诊断完全型大动脉转位的应用价值

The Application Value of Heart Three-Segment Method in Prenatal Echocardiographic Diagnosis of Complete Transposition of the Great Arteries

目的探讨应用心脏三节段法超声心动图诊断胎儿完全型大动脉转位(TGA)的价值。方法回顾性分析产前超声应用心脏三节段法确诊为TGA胎儿21例,并分析其超声心动图图像特征。结果 21例TGA中13例经尸检证实,8例经产后超声心动图证实,其中17例为右转位型(80.95%),4例为左转位型(19.05%)。与产前诊断完全相符16例(76.19%),部分相符5例(23.81%)。部分相符者漏诊冠状动脉起源异常1例,部分型肺静脉异位引流1例,室间隔小缺损2例,房间隔缺损1例。结论心脏三节段法是产前超声诊断TGA是可靠方法,具有很好的临床应用价值。

Objective To explore the application value of heart three- segment ultrasonic diagnosis of fetal heartbeat transposition graph complete transposition of the great arteries(TGA).Methods By retrospectively analyzing of prenatal ultrasound diagnosis of TGA heart three- segment method applied fetal 21 cases,and analyzing the characteristics of echocardiographic images.Results 13 in 21 cases of TGA cases were confirmed by autopsy.8 cases were confirmed by postpartum echocardiography,of which 17 cases for the right type(80.95%),4 cases of left a type(19.05%),16 cases(76.19%) in full compliance with prenatal diagnosis,part 5 cases(23.81%).Some of the matches missing diagnosis of anomalous origin of coronary artery in 1 case,some type of pulmonary vein ectopic drainage in 1 case,small ventricular septal defect in 2 cases,1 case of atrial septal defects.Conclusion Heart three segment method is a reliable method of prenatal ultrasound diagnosis of TGA and has great value in clinical application.
