title: Bilateral ectopic pregnancy after transfer of two embryos.
abstract: OBJECTIVE
  To report a case of bilateral tubal ectopic pregnancy (EP) after the transfer of two embryos.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  A 43-year-old multigravida with bilateral tubal pregnancy.
  
  
  METHODS
  Operative laparoscopy with right linear salpingostomy and left salpingectomy.
  
  
  METHODS
  Laparoscopy revealed an unruptured left isthmic tubal EP and an unruptured right ampullary tubal EP.
  
  
  RESULTS
  Pathology confirmed immature placental villi in the right tube and placental tissue in the left tube. The patient was discharged home without incident on the day after surgery.
  
  
  CONCLUSIONS
  This is a rare case of bilateral tubal pregnancy after the transfer of only two embryos. It is critical to perform a close inspection of the abdomen, pelvis, and contralateral tube after surgery for EP.
