目的:研究经阴道三维超声评估妊娠期宫颈对早产预测的临床应用价值。方法:选择200例诊断为先兆早产的患者,经阴道三维超声观察其宫颈形态并随访妊娠结局。结果:与足月产组对比,早产组的宫颈长度、宫颈漏斗出现比、宫颈漏斗口面积等宫颈各项指标差异均有统计学意义(P<0.05);宫颈越短、出现宫颈漏斗、漏斗口面积越大的孕妇越容易发生早产。结论:经阴道三维超声评估妊娠期孕妇宫颈结构,是预测早产发生的一个有效手段。
Objective: To study the clinical value of transvaginal three-dimensional ultrasound in predicting the prediction of prenatal cervical during pregnancy. Methods: A total of 200 patients diagnosed as threatened preterm labor were selected. Their cervical morphology was observed by vaginal three-dimensional ultrasonography and the pregnancy outcome was followed up. Results: Compared with full-term group, there were significant differences in various indexes of cervix such as cervical length, cervical funnel appearance, cervical funnel mouth area in premature labor group (P <0.05); cervical shorter, cervix funnel, funnel Pregnant women whose mouth area is bigger are more prone to prematurity. Conclusion: Transvaginal three-dimensional ultrasonography to evaluate the cervical structure of pregnant women during pregnancy is an effective measure to predict preterm birth.
