Uterine incarceration in a 9-week multifetal pregnancy resulting from in vitro fertilization. A case report.

BACKGROUND: Although retroversion of the uterus is a common finding, incarceration of the gravid uterus is a rare complication. It occurs usually between the 12th and 16th weeks of gestation and can lead to severe complications. No case of incarceration has been reported before in a multifetal gestation resulting from in vitro fertilization.

CASE: A 35-year-old woman with a triplet pregnancy presented at 9 weeks' gestation with acute urinary retention and was diagnosed with uterine incarceration. This diagnosis was confirmed by ultrasound and was resolved using transvaginal pressure under epidural anesthesia.

CONCLUSION: This is the first reported case of uterine incarceration in a triplet pregnancy that resulted from in vitro fertilization. There is no universal protocol for treatment of incarceration, but several techniques have been described.
