摘要
目的探讨超声心动图对新生儿期永存左上腔静脉的诊断价值。方法我院产前胎儿超声心动图检查时明确诊断或疑为永存左上腔静脉胎儿共11例,出生后再行超声心动图检查,总结永存左上腔静脉的声像图特征。结果 11例胎儿产后均明确诊断为永存左上腔静脉。超声图像表现为永存左上腔静脉全程可显示,位于主动脉弓左侧,由左颈内静脉与左锁骨下静脉交汇形成,呈"Y"形,近心端与冠状静脉窦相连;永存左上腔静脉血流频谱与右侧上腔静脉相一致。结论超声心动图对新生儿期引流入冠状静脉窦到右心房的永存左上腔静脉有较好的诊断价值。
Objective To investigate the value of transthoracic echocardiography in diagnosing persistent left superior vena cava （PLSVC） in neonates. Methods Eleven fetuses suspected with PLSVC by fetal echocardiography underwent transthoracic echocardiography again after birth, the neonatal echocardiographic characteristics of PLSVC were summarized. Results All the 11 cases were diagnosed with PLSVC definitely. The echocardiographic features of PLSVC included the whole vessel left to aortic arch was shown clearly,PLSVC started at the joint of left subclavian vein and left internal jugular vein ,the three vessels constituted ＂Y ＂ sign, the near-end of PLSVC was connected with coronary sinus（CS）. PLSVC had a similar Doppler flow wave with right superior vena cava. Conclusion Echocardiography has better diagnostic value for neonatal PLSVC draining into CS.
