Remember that normally it is only at the end of pregnancy that the cervix opens and changes to allow the birth of the baby. If the internal opening of the cervix is not closed enough, toned, this is called an open bite of the cervix (or cervical open bite).
In this case, a strapping is carried out. The goal is to avoid late miscarriages (from the second trimester) or premature deliveries.
Who are the women at risk?
Some women will have strapping done depending on their history. This is the case when there have been several late abortions, several threats or premature deliveries, a tear of the cervix during previous maneuvers. Strapping is a technique that helps limit recurrence.
To put the cerclage in place, the obstetrician performs a small surgical intervention lasting a few minutes vaginally under general or local anesthesia.
How do you install a strapping?
It exists two different methods of strapping :
- The most common is McDonald’s, which involves tying a non-absorbable thread (usually nylon) around the cervix.
- The other is called the Shirodkar technique: the mucous membrane is incised to surround the cervix with a strip.
The cerclage must be installed, in women at risk, between two and three and a half months of pregnancy. If it is done too late, it will not have the desired effect.
The course of pregnancy after placing a cerclage
No need to stay in bed, but limited activity is strongly recommended to bring your pregnancy to term. Indeed, if your commuting time is too long, if you have to take the car or public transport, your doctor will surely make the decision to stop you earlier than planned.
He can also prescribe antispasmodics, According to the case. You will thus avoid significant fatigue.
Know that expectant mothers who have cervical cerclage are monitored very closelyt. For hugs, ask your doctor. Usually, it is better to wait a bit before resuming sexual activity.
The strapping removed around 38 SA
Women often worry about the consequences of contractions, even though the strapping has not yet been removed. Indeed, if the labor starts with the presence of the cerclage, there is a risk of a tear of the cervix.
Rest assured: the cerclage is removed well before the term of pregnancy, around 37-38 weeks of gestation (SA) when the child can come into the world without any problem.
To remove the strapping, the technique is simpler than to place it. This is done in gynecological consultation using the speculum. The removal is very simple, not painful. It takes just a few minutes.
