产前超声在凶险型前置胎盘合并胎盘植入诊断中的应用价值

Application value of prenatal sonography in diagnosis of pernicious placenta previa combined with placenta implantation

目的探讨产前超声在凶险型前置胎盘合并胎盘植入诊断中的应用价值。方法选取2012-2015年秦皇岛市妇幼保健院收治的疑似凶险型前置胎盘的81例患者为研究对象,所有对象均进行超声以及MRI诊断。结果疑似凶险型前置胎盘产妇的产前超声诊断以及MRI诊断检出率比较,差异无统计学意义(P>0.05),合并胎盘植入产妇的妊娠结局较非合并者差(P<0.05)。结论凶险型前置胎盘合并胎盘植入产妇出现不良妊娠结局的风险比较高,产前超声的诊断效果比较理想,存在风险因素的产妇应当重点进行超声确诊,并采取针对性的处理措施。

Objective To explore the application value of prenatal sonography in diagnosis of pernicious plaeenta previa combined with placenta implantation. Methods Eighty-one patients suspected of pernicious placenta previa were selected from the hospital from 2012 to 2015 as study object, then sonography and magnetic resonance imaging （MRI） were performed. Results There was no statistically significant difference in the detection rate of pernicious placenta previa between prenatal sonography and MRI （ P〉0. 05 ） . The pregnancy outcome of patients with placenta implantation was statistically significantly worse than the patients without placenta implantation （ P〈0. 05 ） . Conclusion The risk of adverse pregnancy outcome is higher in women with pernicious placenta previa combined with placenta implantation compared with the women with pernicious placenta previa. The diagnostic effect of prenatal sonography is ideal, the women with risk factors should be diagnosed by ultrasound, and appropriate measures should be taken to prevent dangerous events.
