Uterine arteriovenous fistula treated with repetitive transcatheter embolization: case report.
Uterine arteriovenous fistula (AVF) is a rare entity, but may lead to life-threatening hemorrhage. Although transcatheter embolization, surgical ligation, or hysterectomy would be considered for treatment of uterine AVF, there is poor knowledge as to how gynecologists can manage the uterine AVF with multiple large inflow arteries. Herein we report a uterine AVF successfully treated using multiple-step transcatheter embolization. The patient, a 58-year-old postmenopausal woman with a history of dilation and curettage, had intermittent massive uterine bleeding. Radiologic imaging revealed the presence of a large vasculature mass. The mass occupied the entire pelvis, and the source of hemorrhage was identified as an accompanying AVF. We thought that surgical intervention was contraindicated because of the potential risk of uncontrollable intraoperative bleeding. Multiple-step transcatheter embolization was performed, with complete resolution of the AVF. Thereafter, the patient had no further uterine bleeding. Multiple-step transcatheter embolization might be the most beneficial and efficient treatment option for a uterine AVF with multiple large inflow arteries.
