三血管-气管心脏超声切面在诊断胎儿永存左上腔静脉的临床应用价值

The diagnositic value of three vessels and trachea view in screening fetal persistent leftsuperior vena cava by ultrasound

目的探讨胎儿心脏三血管-气管超声切面在诊断胎儿永存左上腔静脉的诊断价值。方法我们科室2009年10月～2012年1月，共接诊9例永存左上腔静脉（PLSVC）胎儿心脏畸形的胎儿。总结胎儿心脏三血管-气管切面在PLSVC声像图变化特点，旨在探讨该切面筛查胎儿永存PLSVC的应用价值。结果共诊断PLSVC9例，均经引产尸检和产后超声复查证实。结论本切面在诊断胎儿PLSVC上有很高的临床应用价值。

Objective To evaluate the feasibility and diagnosis value of three vessels and trachea view in screening fetal persistent left superior vena cava （ PLSVC ） by ultrasound. Methods Routine planes and three vessels and trachea view were observed by prena- tal ultrasound from October 2009 to January 2012. Results We found 9 cases of fetal PLSVC. Which 9 cases were proved by review or autopsy by induced abortion. Conclusion The three vessels and trachea view play an important role in screening fetal PLSVC
