title: Uterine incarceration in a 9-week multifetal pregnancy resulting from in vitro fertilization. A case report.
abstract: 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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
