TRANSMYOMETRIAL EMBRYO-TRANSFER AFTER DIFFICULT IMMEDIATE MOCK TRANSCERVICAL TRANSFER

Objective: To evaluate the place of ultrasound-directed transvaginal t ransmyometrial ET in a protocol using both the transcervical and trans myometrial routes in a step-wise fashion. Design: A prospective descri ptive 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 Meas ures: Pregnancy and clinical pregnancy. Results: Four patients became pregnant, including three with clinical pregnancies. Conclusions: In c ases in which transcervical ET is difficult or impossible, transvagina l transmyometrial ET is a viable option. The use of mock transcervical ET immediately before the real transfer would identify patients needi ng transmyometrial ET.
