[Extra-uterine pregnancies after in vitro fertilization. Six case reports].

Ectopic pregnancies after in vitro fertilization (IVF) are more frequent because of the development of assisted reproductive technology. This retrospective study analysed 6 cases of ectopic pregnancy after IVF from the "clinique du Parc" (Tours) during a 3-year period. Tubal disease was found to be the main risk-factor for ectopic pregnancy after IVF heterotopic pregnancy may occur and its diagnosis is often difficult. Management of these ectopic pregnancies included salpingectomy in most cases. Bilateral salpingectomy before IVF may be discussed in cases of severe chronic infectious tubal disease. However, interstitial pregnancy is always possible after tubal occlusion.
