做宫颈环扎手术成功率高吗?Does cervical cerclage have a high success rate?

宫颈环扎手术在妊娠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。

Cervical cerclage is performed around 20 weeks of gestation. The defect of cervical cerclage is that the suture is only external. Once uterine contraction starts, it can not effectively prevent cervical dilatation, and it is easy to induce uterine contraction and miscarriage. Cervical tube infection is easily caused after suture, leading to premature rupture of membranes and miscarriage. The success rate is less than 20%.

安太医院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。

Antai Hospital operates before pregnancy to avoid the possibility of miscarriage caused by suture and does not cause cervical infection. The "Antaihuan" is buried in the muscle of the cervical inner mouth to effectively prevent the expansion of the cervical inner mouth.
