[A modified Shirodkar procedure--double cervical cerclage with an auxiliary loop]

Cervical cerclage high enough at the level of the internal ostium is effective in treating incompetent cervix. And double cerclage at a distance can close the cervix at a higher level even in the case of marked dilation with "bulging membranes". But the higher the cerclage, the more difficult it is to remove the suture at term. To solve this problem, we have designed a modified Shirodkar procedure, "The double cervical cerclage with an auxiliary loop". We have used this new method in 31 cases. In every case the closure was at a high level and the suture was able to be removed very easily at term without any complication.
