title: In vitro fertilization patient presenting in hemorrhagic shock caused by unsuspected heterotopic pregnancy.
abstract: A 30-year-old woman who had undergone in vitro fertilization and embryo transfer (IVF-ET) presented to the emergency department in hemorrhagic shock 4 weeks after a spontaneous abortion. She was found to have a ruptured uterus caused by an unsuspected second pregnancy located in the cornual region of the uterus. Women undergoing IVF-ET are at a higher risk for multiple pregnancies, ectopic pregnancies, and heterotopic pregnancies.
