Transarterial embolization of a nonpuerperal traumatic vulvar hematoma.

Nonpuerperal traumatic vulvar hematomas are relatively uncommon. Conservative and surgical management are the usual treatment options for traumatic vulvar hematomas. There is no report of transarterial embolization of nonpuerperal traumatic vulvar hematoma. We report a 35-year-old woman who presented with a vulvar hematoma caused by an accidental fall on a toy of her child. The hematoma was expanding and was refractory to conservative treatment. A computed tomography (CT) scan revealed active extravasation of contrast material from the left internal pudendal artery. We performed transarterial embolization of the left internal pudendal artery. The left external pudendal artery, which had an anastomosis with the left internal pudendal artery, was also embolized. Postembolization angiography demonstrated no further extravasation of contrast material. We believe that transarterial embolization can be an effective treatment of nonpuerperal traumatic vulvar hematomas when conservative treatment fails.
