Cervical cerclage before blastocyst transfer in patients having cryopreserved embryo transfer.
OBJECTIVE
To present two successful pregnancy results following cervical cerclage before blastocyst transfer in patients who had cryopreserved ET and in whom cervical insufficiency was diagnosed.


METHODS
Case report.


METHODS
Assisted reproduction unit in a university hospital.


METHODS
Two patients with infertility and cervical insufficiency. Both patients signed informed consent.


METHODS
Cervical cerclage before blastocyst transfer.


METHODS
Pregnancy and birth.


RESULTS
Both women achieved pregnancy after transfer of a single, high-quality blastocyst and gave birth to a healthy infant.


CONCLUSIONS
Cervical cerclage can be performed before blastocyst transfer in patients with cervical insufficiency who undergo cryopreserved ET. The procedure is especially relevant to patients in whom the cervical os is dilated and the distal cervical segment is short. Transfer of a single, high-quality blastocyst can result in pregnancy and birth.
