Case Discussion

Uterine arteriovenous malformation (AVM) is often treated with uterine artery embolization (UAE), which may lead to ovarian insufficiency. Thus, avoiding UAE should be considered, particularly in women in the childbearing period.

The patient presented with lower abdominal pain one month after miscarriage with no surgical interference, 7 weeks later AVM disappeared spontaneously.
