摘　　要：目的探讨产科中妊娠晚期超声诊断帆状胎盘的应用价值。方法 60例帆状胎盘患者作为帆状胎盘组,根据患者入院时孕周不同分为中晚期组(孕周25~28周)和晚期组(孕周>28周),每组30例;选择60例健康分娩未诊断帆状胎盘的产妇作为对照组。比较帆状胎盘组与对照组产妇分娩结局;中晚期组和晚期组患者入院时超声诊断准确率。结果帆状胎盘组多胎、早产、宫内死胎、前置胎盘、围生儿死亡、单脐动脉发生率分别为20.0%、21.7%、8.3%、20.0%、18.3%、6.7%,高于对照组的1.7%、0、0、1.7%、3.3%、0,差异具有统计学意义(P<0.05)。晚期组入院时超声诊断帆状胎盘准确率为100.0%,高于中晚期组的80.0%,差异具有统计学意义(P<0.05)。结论帆状胎盘会增加产妇多胎、早产、宫内死胎、前置胎盘、围生儿死亡等不良妊娠结局的发生,妊娠晚期超声诊断帆状胎盘准确率高,值得在临床中推广。Objective To discuss the application value of ultrasonography in the diagnosis of velamentous placenta in late pregnancy in the obstetrics. Methods A total of 60 velamentous placenta was taken as velamentous placenta group, and they were divided into middle and late pregnancy group(25-28 weeks of gestation) and the late pregnancy group(> 28 weeks of gestatio), according to the different gestational weeks of the patients at admission, with 30 cases in each group. 60 healthy parturients without diagnosis of velamentous placenta were selected as the control group. The delivery outcome of velamentous placenta group and control group was compared. Diagnostic accuracy of ultrasound at admission was compared between middle and late pregnancy group and late pregnancy group. Results The incidence of polyembryony, premature delivery, intrauterine fetal death, placenta previa, perinatal deaths, single umbilical artery were 20.0%, 21.7%, 8.3%, 20.0%, 18.3% and 6.7% in velamentous placenta group, which was higher than 1.7%, 0, 0, 1.7%, 3.3% and 0 in the control group, and their difference was statistically significant(P<0.05). The diagnostic accuracy of ultrasound at admission was 100.0% in late pregnancy group, which was higher than 80.0% in middle and late pregnancy group, and the difference was statistically significant(P<0.05). Conclusion Velamentous placenta will increase the occurrence of adverse delivery outcome of polyembryony, premature delivery, intrauterine fetal death, placenta previa, perinatal deaths, and ultrasonography in late pregnancy shows high diagnostic accuracy for velamentous placenta. It is worthy of clinical promotion.
