[Contribution of diagnostic ultrasonography in cases of repeated embryonic implantation failure in fertilization in vitro].

INTRODUCTION

To assess ultrasonic data in the context of repeated failure of implantation in assisted reproduction medicine.

MATERIALS AND

METHODS

We reviewed ultrasonic data (uterine score at follicular and luteal phase). The same ultrasound exploration was repeated for two consecutive cycles to assess the changes in abnormalities observed and compare findings in 16 patients with repeated failure of implantation and in 14 controls. The controls were women who became pregnant within the three months following the exploration. We then introduced acetylsalicylic acid and prednisolone as first line treatment and nitroglycerin as second line treatment to measure the effects induced in 14 pathological uterine scores.

RESULTS

The score obtained under hormonal treatment was representative of other cycles (r = 0.812, p < 0.0014). The score was significantly lower and the luteal uterine artery pulsatility index was significantly higher in the repeated failure group than in the control group (p < 0.0001 and p = 0.008 respectively). For the 14 patients, treatment improved the uterine score in 8 with acetylsalicylic acid and prednisolone and in 4 with nitroglycerin. Two patients did not respond to treatment. Concerning the effect of therapy, of 14 patients, 8 had an improved uterine score with A + P, and with T; 2 patients did not respond to any treatment.

CONCLUSION

The uterine score and luteal artery pulsatility index may be valuable tools for patients with implantation failure who all do not respond to the same therapy.
