title: Pregnancy complicated by asymptomatic uterine arteriovenous malformation: a case report.
abstract: BACKGROUND
  Uterine arteriovenous malformation (AVM) is a rare disease. Percutaneous arterial embolization has been performed for patients who wish to preserve their ability to conceive.
  
  
  METHODS
  A 27-year-old primigravida was admitted for treatment of threatened premature labor at 21 weeks of gestation. She had been diagnosed with asymptomatic uterine AVM 2 years previously. She had not received any treatment before conception. At 41 weeks of gestation she spontaneously delivered a healthy infant weighting 3,154 g. and the Excessive bleeding (1,600 mL) occurred, probably due to eruption of the AVM vessel at the time of parturition. At 3 months postpartum, the patient underwent arterial embolization of AVM.
  
  
  CONCLUSIONS
  The management of uterine AVM should be individualized, taking into account the patient's desire to maintain her fertility and the symptoms.
