Transcatheter uterine artery embolization is well described and performed for treatment of symptomatic uterine leiomyomas, for postpartum hemorrhage, and for hemorrhage following hysterectomy. Embolic agents have included polyvinyl alcohol, gelfoam, coils, and Embospheres®. We present a case of severe uterine hemorrhage after a missed abortion (after two instances of dilatation and curettage), which could not be managed with traditional embolic techniques but was successfully controlled with Onyx®.
