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.
