中孕期产前超声检查宫颈变化的临床意义

目的:通过观测中孕期产前超声检查中宫颈长度及形态变化,探讨其对早产的预测意义。方法:选择500例孕妇(单胎)观察妊娠20～28周宫颈长度及形态变化,并追踪其妊娠结局,分析足月产组与早产组之间的差异。结果:500例孕妇中177例早产,早产率为35.4%,323例足月产。足月产组与早产组的孕妇在中孕期宫颈长度、漏斗形态及既往妊娠史方面有统计学差异。结论:中孕期超声检查可直观清晰显示宫颈长度及形态变化,对先兆早产有一定的预测价值,我们可对高危人群进行动态监测,便于及时处理采取有效措施,减少或避免流产或早产发生。

Cervical changes during second trimester by ultrasonic examination

Objective:To evaluate the value of ultrasonographic examination of the cervical changes in predicting delivery for the women in the mid-second trimester of pregnancy.Methods:Transabdomen ultrasonography was performed in 500 pregnant women with single birth.Cervical length and morphological change of cervix was observed at 20-28 gestational weeks,and pregnant outcome was also followed.Results:There were 177 cases with preterm delivery(35.4%),and 323 cases with full-term birth.There was significant difference in cervical length,cervical funneling shape and the pregnant history between preterm delivery women and full-term women.Conclusions:Ultrasonographic examination can show cervical changes clearly,thus is valuable in predicting preterm delivery.Dynamic monitoring should be performed on pregnant women at high risk to reduce and avoid abortion and preterm delivery.
