超声监测先兆早产患者宫颈的临床意义

Clinical significance of cervical ultrasound surveillance for threatened or preterm delivery

目的 探讨B超监测先兆早产患者子宫颈,检测子宫颈机能不全的临床意义。方法 采用B型超声腹式法,测定35(观察组)和46例正常孕妇(对照组)的子宫颈宫颈内口、颈管长度、宫颈管筒状扩张及胚胎与宫颈的关系。结果 观察组官颈内口(1.66±0.32)cm,颈管长度(2.05±0.63)cm,宫颈管筒状扩张(1.76±2.1)cm,对照组为(1.34±0.14、2.95±0.77、1.26±1.8)cm,两组比较差异极显著(P<0.005)。其中有13例出现“漏斗形成”占37.14%,平均漏斗长度为(2.6cm),漏斗宽度为(1.6cm),早产分娩的10例,占76.9%。结论 超声监测妊娠期宫颈对诊断子宫颈机能不全有较好的预测作用。

Objective:To sqeculate clinical significance of detecting cervical incompetency for threatened and preterm delivery. Methods: Transabdominal ultrasonography was carried out to determine cerbical width, length, dilatation and relationship of enbryo with cervix in 35 study patiens and 46 control subjects.Results:For study group,the mean cervical width,length and dilatation was 1.66±0.32cm,2.05± 0.63cm, 1.76 ± 2.1cm, respectively comparably, control group was 1.34±0.14cm,2.95±0.77cm,and 1.26± 1.8cm, respective...
