产前超声诊断持续性左上腔静脉临床价值分析

Analysis of the clinical value of prenatal ultrasound in the diagnosis of persistent left superior vena cava

目的探讨持续性左上腔静脉(PLSVC)采用产前超声诊断的价值。方法 25000例孕中期孕妇为研究对象,回顾性分析其临床资料。结果经超声检查,70例为PLSVC,检出率为0.28%,其中单纯性PLSVC 35例,占50.00%;单纯合并心外畸形7例,占10.00%;单纯合并心血管畸形14例,占20.00%;同时合并心内及外畸形13例,占18.57%;1例误诊,占1.43%。诊断准确率为98.57%。结论产前超声诊断PLSVC具有较高的临床价值。
