Ultrasonographic diagnosis of uterine artery pseudoaneurysm after hysterectomy.

The development of an arterial pseudoaneurysm is a rare but reported complication of pelvic surgery. Typically the lesion is discovered because the patient has symptoms related to delayed rupture of the pseudoaneurysm, causing hemorrhage. We report a case in which an uterine artery pseudoaneurysm was detected 14 days after vaginal hysterectomy by TVUS, which was performed prior to a transvaginal drainage procedure to treat an infected pelvic hematoma.
