Bilateral tubal pregnancy following in vitro fertilization and transfer of two embryos.
A case of simultaneous bilateral tubal pregnancy after IVF-ET treatment is presented. This condition occurred despite the fact that only two embryos were transferred. Due to misinterpretation of repeated sonographic images, the diagnosis was delayed, and laparatomy with bilateral salpingectomy was not performed until 57 days had passed from the day of ET. Although there is a substantial risk of ectopic pregnancy following IVF-ET, this risk should be reduced as the number of embryos transferred per cycle decreases. This is, to the best of our knowledge, the first report of bilateral tubal pregnancies following the transfer of only two embryos.
