经腹和经会阴联合超声诊断孕中期前置胎盘效果

Transabdominal and transperineal ultrasound in diagnosis of placenta previa in mid-pregnancy

目的:探讨经腹超声和经会阴超声联用在孕中期前置胎盘诊断中的应用价值。方法:对我院经分娩证实为前置胎盘的112例孕中期患者进行回顾性分析,比较单一经腹超声检查和经腹超声联合会阴超声检查的前置胎盘检出率,分析其前置胎盘的具体位置差异。结果:前置胎盘检出率联合超声显著性高于单一经腹超声(P <0. 05);对完全性、边缘性、部分性前置胎盘检出率联合超声稍高于经腹超声,但二者无显著性差异(P> 0. 05);对低置性前置胎盘检出率联合超声显著性高于经腹超声(P <0. 05)。结论:经腹超声联合经会阴超声对孕中期前置胎盘尤其是对于较为隐匿的低置性前置胎盘具有较高的检出率,诊断价值较高,值得临床选择。

Objective：To explore the value of transabdominal and transperineal ultrasound in the diagnosis of placenta previa in mid-pregnancy.Methods：A retrospective analysis was made in 112 cases of placenta previa in mid-pregnancy confirmed by delivery in our hospital. The detection rate of placenta previa was compared between single transabdominal ultrasound and transabdominal ultrasound combined with transperineal ultrasound. The specific location difference of placenta previa was analyzed.Results：The detection rate of placenta previa in combined ultrasound group was significantly higher than that in single transabdominal ultrasound（ P 〈0.05）;the detection rate of complete, marginal and partial placenta previa in combined ultrasound group was slightly higher than that in transabdominal ultrasound, but there was no significant difference between them（ P 〉0.05）;the detection rate of low-lying placenta previa in combined ultrasound group was higher than that in transabdominal ultrasound group（ P 〈0.05）.Conclusion：Transabdominal ultrasound combined with transperineal ultrasound has a high detection rate for placenta previa in mid-pregnancy, especially for concealed low-lying placenta previa.
