Subchorionic hematoma associated with heterotopic pregnancy following in vitro fertilization: a case report.
BACKGROUND
After treatment for infertility using in vitro fertilization (IVF)-embryo transfer, a high index of suspicion must be maintained for early diagnosis and treatment of concurrent ectopic pregnancy; however, the likelihood of a positive outcome for the intrauterine pregnancy remains uncertain.


METHODS
A subchorionic hematoma threatening an intrauterine gestation noted concurrently with ultrasound diagnosis of a heterotopic IVF pregnancy resolved following laparoscopic salpingectomy.


CONCLUSIONS
Although symptomatic subchorionic hematoma may be associated with an increase in the rate of spontaneous miscarriage for a singleton pregnancy, it may not present a similar risk in the presence of a concurrent heterotopic gestation.
