超声诊断前置胎盘的临床意义

Clinical Significance of Joint Diagnosis on Placenta Previa

目的%探讨超声诊断前置胎盘的价值。方法%88例胎盘前置状态,28周后经腹联合经会阴超声检查诊断结果与产后对照。结果%产后证实35例前置胎盘,经腹超声检查诊断前置胎盘31例。其中完全性前置胎盘4例,部分性前置胎盘9例,边缘性前置胎盘12例,低置胎盘6例。漏诊4例,误诊2例,符合29例,诊断符合率82.86%。经腹联合经会阴超声检查,漏诊4例得以纠正,但仍有两例误诊。一例侧壁低置胎盘误诊为完全性前置胎盘,一例后壁边缘性前置胎盘误诊为部分性前置胎盘。诊断符合率94.29%。结论%超声诊断前置胎盘安全、准确、费用低、可重复,是目前诊断前置胎盘首选的检查方法。联合应用可提高诊断的准确性率。

Objective To explore the value of ultrasonic diagnosis of placenta previa.Methods 88 cases of placenta previa,28 weeks after abdominal sonography diagnosis results with postpartum contrast.The postnatal outcome was confirmed in 35 cases of placenta previa,transabdominal ultrasound examination in the diagnosis of 31 cases of placenta previa.One of complete placenta previa in 4 cases,partial placenta previa in 9 cases,marginal placenta 12 cases,low lying placenta 6 cases.Missed diagnosis of 4 cases,misdiagnosis of 2 cases and 29 accordant cases,diagnosis coincidence rate is 82.86%.Transabdominal combined transperineal ultrasound examination,4 cases were missed diagnosis is correct,but there are still two cases.A case of side wall of low lying placenta misdiagnosed as complete placenta previa,a case of posterior marginal placenta misdiagnosed as part of placenta previa.Diagnosis coincidence rate is 94.29%.Conclusion ultrasound diagnosis of placenta previa is safe,accurate,low cost,repeatable,is currently the diagnosis of placenta previa preferred inspection method.The United application may improve the diagnostic accuracy rate.
