Objective:
To report a case of bilateral tubal ectopic pregnancy (EP) after the transfer of two embryos.
Design:
Case report.
Setting:
University hospital.
Patient(S):
A 43-year-old multigravida with bilateral tubal pregnancy.
Intervention(S):
Operative laparoscopy with right linear salpingostomy and left salpingectomy.
Main Outcome Measure(S):
Laparoscopy revealed an unruptured left isthmic tubal EP and an unruptured right ampullary tubal EP.
Result(S):
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.
Conclusion(S):
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.
