מה שם השיטה לאיתור מידע נוסף

לשיטה קוראים של החזרת עוברים בהזרקה ישירות לרירית הרחם קוראים: transmyometrial-subendometrial embryo transfer כאשר החזרת עוברים מבוצעת בהנחית אולטראסאונד עם מחט שחודרת דרך דופן הרחם או direct intraendometrial embryo transfer כאשר החזרת העוברים מבוצעת בהנחיית היסטרוסקופ. השיטה מוכרת כבר כעשר שנים, ולצערי מחקרים מישראל (ראי למטה) הוכיחו שלשיטה זו אין יתרון ברור על השיטות המקובלות. כמובן שבמקרים של הצרות קיצונית בצוואר הרחם יש לשיטה זו יתרון מסוים, אבל כאמור אין כאן בינתיים בשורה של ממש. Twin pregnancy following transmyometrial-subendometrial embryo transfer for Fertil Steril 1997 Jun;67(6):1073-6 Comparison of transmyometrial and transcervical embryo transfer in patients with previously failed in vitro fertilization-embryo transfer cycles and/or cervical stenosis. Groutz A, Lessing JB, Wolf Y, Azem F, Yovel I, Amit A. IVF-ET Unit, Serlin Maternity Hospital, Tel Aviv, Israel. OBJECTIVE: To compare ultrasound-guided transmyometrial and transcervical ET in patients with cervical stenosis or in patients who failed to conceive after at least three previous IVF-ET cycles. DESIGN: A prospective, randomized study. SETTING: The IVF-ET Unit at Serlin Maternity Hospital. PATIENT(S): Forty patients undergoing IVF-ET. INTERVENTION(S): Ultrasound-guided transvaginal, transmyometrial, versus transcervical ET. MAIN OUTCOME MEASURE(S): Clinical pregnancy rate. RESULT(S): Transmyometrial ET was performed in 20 patients and resulted in one clinical pregnancy. Transcervical ET, performed in another 20 similar patients, resulted in three clinical pregnancies. CONCLUSION(S): No benefit was derived by electing transmyometrial ET in preference to transcervical ET in patients who had failed to conceive in previous cycles. Assisted implantation: direct intraendometrial embryo transfer. Gynecol Obstet Invest 1997;43(2):73-5 Itskovitz-Eldor J, Filmar S, Manor D, Stein D, Lightman A, Kol S. Department of Obstetrics and Gynecology, Rambam Medical Center, Haifa, Israel. We report herein a technique for direct intraendometrial transfer (DIET) of human embryos. In this study we evaluated whether 2-day embryos injected into the endometrial stroma can develop normally into viable pregnancies. After in vitro fertilization the embryos were injected into the endometrium of 14 women under direct visualization using a CO2-pulsed flexible hysteroscope. A total of 44 embryos were transferred, resulting in 2 clinical (14.3% per cycle) and 2 chemical pregnancies. In 1 patient, amniocentesis revealed monosomy X and the pregnancy was terminated at 18 weeks. The 2nd patient had an uneventful pregnancy and delivered a healthy baby. The results from the present study, demonstrating a low implantation rate after DIET of 2-day embryos, suggest that the endometrial stroma does not provide an optimal environment for early embryonic development. The acidifying effect of CO2 used for insufflation may also explain the low pregnancy rate after DIET. We conclude that it is possible to achieve pregnancy by DIET in humans, but presently this procedure can be considered only in cases where the implantation site needs to be precisely determined.
