An unexpected quadruplet heterotopic pregnancy after bilateral salpingectomy and replacement of three embryos.
OBJECTIVE
To report a case of combined intrauterine and interstitial twin pregnancies after bilateral salpingectomy and IVF with replacement of three embryos.


METHODS
Case report.


METHODS
University hospital.


METHODS
A 31-year-old woman known to have bilateral salpingectomy for ectopic pregnancies who underwent IVF.


METHODS
Laparotomy.


METHODS
Postoperation intrauterine monozygotic twins survival and birth.


RESULTS
After removing the interstitial monozygotic twin pregnancy, the patient had an uneventful postoperative course and delivered two healthy girls by cesarean section at 38 weeks' gestation.


CONCLUSIONS
Heterotopic pregnancy can still occur in women treated by IVF after bilateral salpingectomy. The early sonography follow-up of IVF pregnancy would be of value because of the reported higher incidence of pathological pregnancies and especially monozygotic twinning.
