Ovarian arteriovenous fistula. An unusual cause of abdominal pain

Arteriovenous fistulae of the ovarian artery may develop after gynecologic surgery. A case that occurred 9 years after hysterectomy with bilateral oophorectomy is presented and discussed. It illustrates an unusual cause of left lower quadrant abdominal pain. Surgical removal of the ovarian arteriovenous fistula resulted in complete relief of the patient's symptoms. This uncommon entity must be considered when dealing with lower quadrant pain and a past history of hysterectomy.
