晚期流产宫颈松：分别于2016年孕20周及2018年孕孕26周无诱因胎膜早破自然流产各一次。扩宫试验：8号扩宫棒顺利通过。能否做安太环埋箍?

Late miscarriage cervix pine: in 2016 pregnancy 20 weeks and 2018 pregnancy 26 weeks without the cause of early rupture of the fetal membrane spontaneous miscarriage. Palace expansion test: No. 8 palace expansion stick passed smoothly. Can you do an anterahuan hoop?

陈凤林教授指出：宫颈机能不全，晚期复发性流产4次能埋箍，最好孕前埋箍。

Professor Chenfenglin pointed out: Cervical function is incomplete, late recurrent miscarriage can be buried four times, the best pre-pregnancy placement.
