Pregnancy after medical management of a uterine arteriovenous malformation. A case report.

BACKGROUND

The natural history of conservatively managed uterine arteriovenous malformations is largely unknown, and the risks associated with subsequent pregnancy and vaginal delivery have not been established.

CASE: A multiparous woman with a previously reported history of uterine arteriovenous malformation was monitored throughout pregnancy and vaginal delivery. Serial ultrasound studies were performed prior to a successful induction of labor for severe preeclampsia at 34 weeks' gestation.

CONCLUSION

To our knowledge, this is the first report of pregnancy and vaginal delivery in a woman with a prior history of a medically managed uterine arteriovenous malformation. Noninvasive treatment of uterine arteriovenous malformations is rare, and the potential long-term risks of this approach, including pregnancy, remain uncertain.
