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

BACKGROUND: The natural history of conservatively managed uterine arteriove nous malformations is largely unknown, and the risks associated with subseq uent pregnancy and vaginal delivery have not been established. CASE: A multiparous woman with a previously reported history of uterine art eriovenous malformation was monitored throughout pregnancy and vaginal deli very. Serial ultrasound studies were performed prior to a successful induct ion of labor for severe preeclampsia at 34 weeks' gestation. CONCLUSION: To our knowledge, this is the first report of pregnancy and vag inal delivery in a woman with a prior history of a medically managed uterin e arteriovenous malformation. Noninvasive treatment of uterine arteriovenou s malformations is rare, and the potential long-term risks of this approach , including pregnancy, remain uncertain.
