彩色多普勒超声对新生儿完全性大动脉转位的诊断价值

目的 了解新生儿完全性大动脉转位（ＴＧＡ）的超声特点。评价超声在ＴＧＡ早期诊断中的价值。方法 回顾分析３５例新生儿ＴＧＡ的超声表现并与手术、心导管和尸解结果对照。结果 单纯ＴＧＡ６例，合并室间隔缺损、房间隔缺损、动脉导管未闭（ＰＤＡ）２０例，房室间隔缺损１例，肺动脉狭窄１例，肺干静脉畸形引流１例，三尖瓣闭锁２例，右位心２例，冠状动脉异常１例，合并３种以上其他先心病共１３例。大动脉位置关系与４例手术、１例心导管、２例尸解结果一致。１例ＰＤＡ彩超漏诊。结论 新生儿ＴＧＡ需早期诊断，超声检查无创、准确为临床提供可靠信息。

Evaluation of Echocardiography on Complete Transposition of the Great Arteries in Newborns

Objective To evaluate echocardiography in early diagnosis by studying echocardiography features of TGA in newborns. Methods 35 cases of neonatal TGA were analyzed retrospectively and compared with the findings of operation, catheterization and autopsy. Results Among the 35 cases,20 cases were with ventricular septal defect(VSD),atrial septal defect(ASD) and patent ductus arteriosus(PDA).1 case with endocardial cushion defect(ECD) ,1 case with pulmonary valve stenosis(PS),1 case with total anomalous pulmonary venous connection(TAPVC),2 cases with tricuspid atresia(TA) and 1 case with anomalous origin of coronary artery.13 cases were with more than three kinds of other congenital heart diseases. Echocardiography showed the changes of the great arteries were compatible with those seen under 4 cases of operation,1 case of catheterization and 2 cases of autopsy.1 case of PDA was missed by Echocardiography. Conclusion TGA in newborns should be early diagnosed. Echocardiography is an invasive and reliable technique and it can provide accurate informations for diagnosis of newborns with TGA.
