Ovarian pregnancy resulting from cornual fistulae in a woman who had undergone bilateral salpingectomy

Objective: To report a case of ovarian pregnancy following in vitro fertilization-embryo transfer (IVF-ET) treatment for which the cornual fistulae was the most probable explanation of the cause. Design: Case report. Setting: University department and assisted reproduction unit. Patient(s): A 29-year-old woman with primary infertility. Intervention(s): Hydrosalpinx of the bilateral fallopian tubes has been noted in patients who have decreased pregnancy rates in the IVF-ET treatment cycles. Salpingectomy before IVF cycles has been suggested to increase the pregnancy rate. We report a patient who presented with bilateral hydrosalpinx for whom bilateral salpingectomy was performed before IVF treatment. Main Outcome Measure(s): Clinical pregnancy. Result(s): The treatment cycle resulted in a primary ovarian pregnancy and required laparoscopic operation. A cornual fistulae was found that have might led to ectopic implantation of the embryos. Conclusion(s): Ovarian pregnancy may be an unexpected complication of those receiving bilateral salpingectomy before IVF treatment. The presence of cornual fistulae after salpingectomy was probably the cause of the ectopic pregnancy. (C)2005 by American Society for Reproductive Medicine.
