宫颈环扎预防流产成功率高不高?Does cervix ring tie prevent miscarriage success rate is high?

陈凤林教授指出：宫颈环扎预防流产成功率并不高，传统的宫颈环扎在妊娠20周左右将宫口用丝线环扎，缺陷是缝扎的只是外口,一旦宫缩发动,不能有效阻止宫颈扩张,且易诱发宫缩而流产，缝扎后还容易引起宫颈管感染，导致胎膜早破流产，成功率不足20%左右。

Professor Chenfenglin pointed out: The success rate of cervical cervix in preventing miscarriage is not high. The traditional cervix ring is tied with silk thread around 20 weeks of pregnancy. The defect is that the suture is only external. Once the contractions are started, they can not effectively stop the cervical expansion. And easy to induce contractions and miscarriage, suture is also easy to cause cervical canal infection, resulting in premature rupture of the fetal membrane miscarriage, the success rate of less than 20 %.
