摘要
目的:探讨经阴道超声(TVS)在诊断前置胎盘及并发症中的应用价值。方法:对55例临床怀疑前置胎盘孕妇TVS检查进行定位并观察是否有并发症的存在与产时及病理结果相比较。结果:TVS检查对前置胎盘的诊断与产时相比其准确率为95.8%,检查后无出血增多及感染,前置胎盘伴有并发症的大出血风险预测率73%。结论:TVS对前置胎盘的诊断安全且准确率高,其风险预测为临床提供充分的处理依据。
Objective：To approach the diagnostic value and safety of Transvaginal ultrasonography（TVS） in diagnosing placenta praevia.Methods：We used TVS to localize and investigate placenta previa in 55 pregnant women,and verified the results during delivery.Results：The diagnostic accuracy of TVS for placenta previa was 95.8%,and no TVS-related hemorrhage or infections occurred.The predictive value for intrapartum hemorrhea was 73%.Conclusion：TVS is a safe and accurate diagnostic method for placenta praevia.
