Pregnancy after percutaneous ethanol sclerotherapy for uterine arteriovenous fistula: Case report

Uterine arteriovenous fistula is a rare but life-threatening gynecologic entity. Meanwhile, long-term radiation exposure will do serious harm to doctors' health. So we improve the operation method to reduce the radiation exposure time. The patient, a 24-years-old woman with a history of dilation and curettage, had long-term menorrhagia and anemia. Uterine arteriovenous fistula was confirmed by ultrasonography and computed tomography angiograph. Percutaneous anhydrous ethanol sclerotherapy was performed under the guidance of the X-ray imaging. The patient was followed up for 2 years without recurrence and had normal menstruation. Recently, she is successfully pregnant again. Percutaneous anhydrous ethanol sclerotherapy is a new option treating uterine arteriovenous fistula, which can greatly shorten the irradiation time and reduce the recurrence rate and has no obvious adverse effect on fertility.
