Application of ultrasound in the diagnosis of velamentous placenta on late pregnancy in obstetrics

目的 研究妊娠晚期超声诊断帆状胎盘在产科中的应用。方法 选取2014年1月~2015年3月在我院住院分娩,分娩后确诊帆状胎盘的产妇40例作为观察组。随机抽取同期住院分娩的非帆状胎盘产妇40例作为对照组。比较两组孕妇的临床特点及产前产后诊断结果。结果 观察组孕妇产后出血量和胎心监护异常例数高于对照组,两组患者产后出血量差异有统计学意义（P〈0.05）。两组孕妇在分娩方式、新生儿预后不良方面差异有统计学意义（P〈0.05）。40例产妇,产前超声诊断为帆状胎盘38例,产后帆状胎盘产妇40例,产前诊断率100%,产前超声漏诊2例,漏诊率5%。结论 超声检查能显著提高帆状胎盘在产前诊断率。

Objective To study the application of ultrasound in the diagnosis of velamentous placenta on late pregnancy in obstetrics. Methods 40 cases of maternal,who were diagnosed velamentous placenta after delivery in our hospital from January 2014 to March 2015,were selected as the study objects of observation group. In the same period,40 cases of pregnant women with non - velamentous placenta were randomly selected as the control group. Clinical characteristics and prenatal and postnatal diagnosis results of the two groups were compared. Results The amount of postpartum hemorrhage and abnormal fetal heart rate monitoring of the observation group were higher than those of the control group, the differences were significant between the two groups （P 〈 0.05）. In the mode of delivery and poor prognosis aspects of newborn,the two groups were not significant（P 〈 0.05）.Among the 40 cases of maternal, there were 38 cases diagnosed as velamentous placenta with prenatal ultrasonic, and there were 40 cases diagnosed as velamentous placenta postnatal. Diagnosis rate Postnatal was 100%, and prenatal ultrasound missed two cases, and misdiagnosis rate was 5%. Conclusion Ultrasonography can significantly improve velamentous placenta in prenatal diagnosis.
