I had a LEEP and a Cold Knife Cone BX in 2005.Up until May 2007, when I got pregnant,my husband and I always used BC.The risk of IC depends on several factors. The amount of tissue removed, how deep the HPV invaded the cervixand the individual person. Since I had 2 surgeries, the amount of tissue removed was more than normal. My cervix started out roughly at 3cm. The normal cervix is roughly 4-4.5cm. And every woman can be different....a woman may have a short cervix but it might not be weak....resulting in a normal pregnancy. It could also be long and not as strong resulting in IC. Everyone is different.
My doctor started checking my cervix at 8 weeks, 11 weeks and then at 15 weeks where it showed that it had started to shorten and I had spotting. I was at 2cm. My doc decided to do the cerclage. I got a double stitch McDonald and then stayed on some form of bedrest from 15weeks-37.5 weeks.
A cerclage is usually done betweek 12-16 weeks. The earlier the better but can be placed later if need be... If it is noticed that the cervix is shortening after 15 or so weeks a rescue cerclage could then be attempted. A rescue cerclage placement is not without risk. Rescue cerclages can carry a higher chance for infection and rupture of membranes from the advancing growth of baby.
Success rates with cerclages are as high as 85-90 percent with preventatively placed cerclages between 11-14 weeks. Depending on which type of cerclage suture placed, they may either be removed at or around 37 weeks to allow for vaginal delivery or stay in place which requires a c-section delivery.
