Successful Embolization of Collaterals from the Round Ligament Artery during Uterine Artery Embolization for Traumatic Uterine Leiomyoma Rupture: A Case Report.

We describe the case of a 48-year-old woman who presented with traumatic rupture of a giant leiomyoma and massive hemoperitoneum caused by slipping and falling in the bathroom. She was in shock on arrival, and resuscitation was performed. Contrast-enhanced computed tomography showed massive intra-abdominal hematoma and extravasation from the subserous leiomyoma. Uterine artery embolization was performed, but she went into shock again after 6 h. The second contrast-enhanced computed tomography revealed persistence of extravasation. During 2nd UAE, an angiogram revealed extravasation originating from left round ligament artery. After the embolization of the left round ligament and bilateral uterine arteries, the patient recovered from shock. Total abdominal hysterectomy was performed on day 2 of admission to prevent re-bleeding and infection, then she discharged on day 19 of admission.
