孕中期前置胎盘诊断中经腹超声和经会阴超声联合应用的价值分析

The value of transabdominal ultrasonography and transperineal ultrasonography in the diagnosis of placenta previa in the second trimester of pregnancy

目的探讨孕中期前置胎盘诊断中经腹超声与经会阴超声联合应用的临床价值。方法选取我院2015年2月—2017年3月期间收治的60例孕中期前置胎盘患者,分别实施经腹超声、经会阴超声以及两者联合诊断,对比诊断准确率。结果 60例患者使用经腹超声诊断的准确率为71.67%,使用经会阴超声诊断的准确率为83.33%,使用经腹超声与经会阴超声联合诊断的准确率为96.67%;联合检查方式的诊断准确率远高于单纯使用其中一种诊断方式,差异具有统计学意义(P<0.05)。结论经腹超声联合经会阴超声在孕中期前置胎盘患者的临床诊断中具有较高的应用价值,能够有效提高诊断准确率,减少漏诊情况的发生,值得推广。

Objective The thesis mainly discuss the clinical value of diagnosis of placenta previa in second trimester transabdominal ultrasound and perineal ultrasound application. Methods According to the method of random number in our hospital from February 2015 to March 2017 during the 60 pregnant patients with placenta previa,all patients were performed transabdominal ultrasound,perineal ultrasound and combined diagnostic accuracy of both,compared two groups of patients with ultrasound diagnosis and misdiagnosis. Results the accuracy of diagnosis by transabdominal ultrasound in 60 patients was 71.67. The diagnostic accuracy of transperineal ultrasound was 83.33; The diagnostic accuracy of transabdominal ultrasound combined with transperineal ultrasound was 96.67. The diagnostic accuracy of combined examination was much higher than that of only one of them,and the difference was statistically significant （P〈0.05）.Conclusion The application value of abdominal ultrasound combined with transperineal ultrasound in clinical diagnosis of pregnancy in patients with placenta previa is high,can effectively improve the the accuracy of clinical diagnosis,reduce misdiagnosis happening,has higher application value.
