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

Application Value of Transabdominal Ultrasound and Transperineal Ultrasound in the Diagnosis of Placenta Previa in the Second Trimester

目的:探究孕中期前置胎盘孕妇在使用经腹超声和经会阴超声联用后的诊断价值。方法:研究对象为2014年6月~2016年6月收入的80例疑似孕中期前置胎盘孕妇,对其展开回顾性分析,本院分别采用经腹超声及经腹+经会阴超声联合诊断两种方式对其进行诊断。诊断后经手术即实验室检查发现有72例发生孕中期前置胎盘,现比较两种诊断方式的实施对灵敏度、准确度、特异度的影响。结果:超声联合诊断的灵敏度(98.44%)、准确率(94.44%)及特异度(71.43%)显著比经腹超声诊断的(90.47%)、(84.72%)、(44.44%)高(χ^2=6.064、5.061、14.946,P<0.05)。结论:孕中期前置胎盘经过经腹超声和经会阴超声联用诊断后能够形成优势互补,灵敏度更高,诊断结果更为准确。

Objective:To explore the diagnostic value of pregnant women with placenta previa in the second trimester after combined use of transabdominal ultrasound and transperineal ultrasound.Methods:A retrospective analysis was performed on 80 pregnant women with suspected placenta previa who had income from 2014.6~2016.6.The hospital diagnosed them with trans-abdominal ultrasound and trans-abdominal trans-perineal ultrasound.After the diagnosis,72 cases of placenta previa were found in the second trimester through laboratory examination after surgery.The effects of the two diagnostic methods on sensitivity,accuracy,and specificity are compared.Results:The sensitivity(98.44%),accuracy(94.44%),and specificity(71.43%)of the combined ultrasound diagnosis were significantly higher than those of(90.47%),(84.72%),and(44.44%)diagnosed by abdominal ultrasound(χ^2=6.064),5.061,14.946,P<0.05).Conclusion:The combined diagnosis of placenta previa with transabdominal ultrasound and transperineal ultrasound in the second trimester of pregnancy can form complementary advantages,higher sensitivity,and more accurate diagnosis results.
