B超检测子宫下段厚度对剖宫产术后患者再妊娠阴道分娩的意义

Significance of B ultrasound measurement of lower uterine segment thickness in vaginal birth after cesarean section

目的探讨应用B超检测妊娠晚期子宫下段厚度对剖宫产术后阴道分娩的指导意义。方法应用B超检测88例有剖宫产史孕妇的子宫下段厚度,并与分娩及手术结果对比。结果 B超检测妊娠晚期子宫下段厚度≥2mm者可行阴道试产。结论应用B超检测子宫下段厚度对剖宫产术后妊娠患者分娩方式的选择提供有利的指导,并能预测先兆子宫破裂的发生。

Objective To investigate the the significance of B ultrasound measurement of the lower uterine segment（LUS） thickness in vaginal birth after cesarean section（VBAC）.Methods Using B ultrasound measure the LUS thickness in 88 women with previous caesarean section,the outcome is contrasted with delivery and operation.Results A sonographic LUS thickness of ≥2mm was allowed to vaginal birth.Conclusions With B ultrasound measurement of the LUS thickness,women with previous caesarean section can get favorable guidance,also can predict aura uterine rupture.
