Combined interstitial and intrauterine pregnancies after in-vitro fertilization and embryo transfer

Abstract

A case of combined interstitial and intrauterine pregnancies after bilateral salpingectomy and in-vitro fertilization with embryo transfer is reported. The case was incorrectly diagnosed ultrasonographically as intrauterine triplets at 7 weeks gestation. The patient suffered from intra-abdominal bleeding at 14 weeks gestation. At laparotomy, a ruptured left interstitial pregnancy with a non-viable fetus was found in the left abdominal quadrant. The uterine defect was successfully repaired and gestational contents and blood were evacuated from the abdominal cavity. The intrauterine twin pregnancy progressed without incident, and a Caesarean section was performed at 36 weeks gestation, resulting in healthy male and female infants.
