Perforated Cerclage Pessaries

This Cerclage pessary is used to treat pregnant women with cervical incompetence in order to support the cervix and turn it towards the sacrum.

It may be indicated in pregnancies with a history of premature labour, multiple pregnancies or mothers who are exposed to physical strain (e.g. standing for a long time). It may also be indicated in pregnant women suffering from prolapse of the genital organs.

Using transvaginal sonography in recumbent or upright position we have established normal values for the cervical length and an opening of the cervical os (funnelling) for singleton and twin pregnancies. Low values of the cervical length and high values of the opening of the cervical os (Funneling) help identify patients who might benefit from pessary placement.

Inserting a Cerclage Pessary

The pessary can easily be folded and inserted without pain. Before the application, it is recommended to exclude and treat if necessary cervical or vaginal infection. In general, cerclage pessaries should have a height of 17-25mm in singleton and a height of 25-30mm in twin or multiple pregnancies or pregnant patients with complaints of prolapse.

The width of the upper and lower diameter should be chosen depending on the individual constitution of the pregnant patient.
