Late leiomyoma expulsion after uterine artery embolization

Abstract

A case of late expulsion of a leiomyoma after uterine artery embolization (UAE) is reported in a 49-year-old woman who underwent UAE for a huge (13 cm x 12 cm; 1,061 cm(3)) bleeding- and bulk-related intramural leiomyoma diagnosed with ultrasonography. Free-flow embolization was performed with 150-400-microm polyvinyl alcohol particles and absorbable particle sponge. Symptoms and myoma size were successfully controlled until 44 months, at which time the patient reported vaginal discharge. A 7-cm necrotic, partly submucosal leiomyoma was detected. The patient refused hysterectomy and spontaneously expelled the leiomyoma through the cervix 6 months later. In conclusion, UAE necessitates long-term follow-up and women should be warned of late complications.
