BACKGROUND:

uterine arteriovenous malformations constitute a group endometrial and myometrial vascularization disorders characterized by the formation of heterogeneous and aberrant communications between the arterial and venous territories, producing abundant genital bleeding pictures as well as hemodynamic instability.

CLINICAL CASE:

a patient who underwent a hemostatic uterine D&C developed a uterine arteriovenous fistula that was treated through selective embolization of the left uterine artery; she became pregnant after three months of the procedure, she presented a normal pregnancy with satisfactory perinatal outcomes.

CONCLUSION:

the diagnosis of arteriovenous malformations is mainly clinical, although confirmation depends on imaging tests. A Doppler ultrasound and angiography are the preferred techniques to diagnose lesions and to plan subsequent treatment, a decision that will depend on the patient’s reproductive wishes. Currently, the choice treatment for patients who want to become pregnant is a radiologically guided selective endovascular embolization. Oral contraceptives, resection hysteroscopy techniques or hysterectomy are other therapeutic options that may be considered based on the parameters indicated.
