Heterotopic pregnancy obtained after in-vitro fertilization and embryo transfer following bilateral total salpingectomy: case report.

Heterotopic (coexistent ectopic and intra-uterine) pregnancy is common following in-vitro fertilization and multiple embryo transfer. Total bilateral salpingectomy is generally considered to eliminate the risk of ectopic, and hence heterotopic pregnancy. This is, however, not strictly correct as it does not eliminate the risk of interstitial tubal pregnancy. This is the first reported case of a heterotopic pregnancy following total bilateral salpingectomy. The diagnostic pitfalls and a suggested method of avoiding them are discussed.
