Successful pregnancies with the use of laminaria tents before embryo transfer for refractory cervical stenosis.
OBJECTIVE
To determine whether laminaria tents are a safe and effective method of cervical dilatation in patients with a history of cervical stenosis and difficult ET.


METHODS
Case reports describing two patients.


METHODS
Tertiary care, assisted reproduction practice.


METHODS
Two patients with cervical stenosis and a history of multiple failed cycles of IVF.


METHODS
Laminaria tents were placed intracervically before ET.


METHODS
Presence of a gestational sac and fetal heartbeat on ultrasound.


RESULTS
Successful clinical pregnancies occurred in both patients after laminaria placement and ET.


CONCLUSIONS
Laminaria tent cervical dilatation appears to be a safe and effective option to assist ET in patients with a history of cervical stenosis.
