宫颈环扎效果怎么样?怀孕后何时能做环扎?How about the effect of cervical cerclage? When can we do cerclage after pregnancy?

陈凤林教授指出：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 Chen Fenglin pointed out that: around 20 weeks of gestation, the defect is that the suture is only outside the mouth. Once contraction starts, it can not effectively prevent cervical dilatation, and it is easy to induce uterine contraction and miscarriage. After suture, it is easy to cause cervical tube infection, leading to premature rupture of membranes and miscarriage. The success rate is less than 20%.

创新点和学术价值：在孕前手术避免了缝扎导致流产的可能性，也不会导致宫颈感染。将“安太环”埋在宫颈内口的肌肉内，有效阻止宫颈内口的扩张。

Innovation and academic value: Pre-pregnancy surgery avoids the possibility of suture leading to miscarriage and cervical infection. The "Antaihuan" is buried in the muscle of the cervical inner mouth to effectively prevent the expansion of the cervical inner mouth.
