[The value of hysteroscopy after repeated implantation failures with in vitro fertilization].

OBJECT: we attempt to determine the usefulness of uterine re-assessment by hysteroscopy in women with two unsuccessful IVF-ET attempts. MATERIAL AND METHOD: This retrospective study concerns seventy-three infertile women who have had a repeat uterine hysteroscopy after two implantation failures in IVF. RESULTS: In half the cases, an abnormality was diagnosed. Cervical abnormalities (synechia, polyp, false passage) and hormono-dependent abnormalities (polyp, hyperplasia, submucous myoma) were the most frequent findings. The rate of pregnant women raises to twenty-two percent after treatment of these abnormalities. CONCLUSION: Regarding our experience, it seems legitimate to perform hysteroscopy in women who have had two IVF-ET failures before attempting a third procedure.

[Can the type of GnRH used during long in vitro fertilization protocols influence the pregnancy rate?].

Luteal defect is common during IVF cycles using GnRH agonist. It could be interesting to make up for this problem by using short acting GnRH agonist (effective for 24 hours), more handy at the end of the stimulation. 160 patients included in a long IVF protocol at the Bordeaux CHRU FIV center have been randomized, from September 1993 to August 1994, for the analog's choice (long or short) at the beginning of the stimulation. The stimulation's parameters, the hormonal dosages and the pregnancy rate are independent of the galenic form used. In close, the use of long-acting GnRH analog (sympler to use) sems preferable.

[Thromboembolism and ovarian hyperstimulation].

Three new cases of thromboembolic accidents involving the superior vena cave were associated with ovarian hyperstimulation and multiple pregnancy. On the basis of a review of the literature, three syndromes were individualized. First embolic arteries are infrequent and serious with an important morbidity; low doses of gonadotrophines is sufficient for causing this pathology. Second, thrombosis of the superior vena cava is late, during in vitro fertilization regimens with GnRH analogs complicated with serious hyperstimulation (degree III). Third, pregnancy is always present; pulmonary complications are very uncommon. Thrombosis of inferior vena cava is late, pregnancy is often present but women are frequently at risk of thromboembolic accident. Prevention of hyperstimulation is important. When present, HBPM is recommended for prevention of thromboembolism. Diagnostic of thrombosis is made with clinical examination and morphologic complementary exams such colour-vascular Doppler and magnetic resonance imaging. Curative treatment requires heparinization.
