Transmyometrial embryo transfer after difficult immediate mock transcervical transfer.

OBJECTIVE

To evaluate the place of ultrasound-directed transvaginal transmyometrial ET in a protocol using both the transcervical and transmyometrial routes in a step-wise fashion.

DESIGN

A prospective descriptive clinical study.

SETTING

A university-based assisted conception unit.

PATIENTS

Thirteen patients who had difficult or impossible mock transcervical ET immediately before the real transfer.

INTERVENTION

Ultrasound-directed transvaginal transmyometrial ET.

MAIN OUTCOME MEASURES

Pregnancy and clinical pregnancy.

RESULTS

Four patients became pregnant, including three with clinical pregnancies.

CONCLUSIONS

In cases in which transcervical ET isd difficult or impossible, transvaginal transmyometrial ET is a viable option. The use of mock transcervical ET immediately before the real transfer would identify patients needing transmyometrial ET.
