Uterine arteriovenous malformation (UAVM) is a potentially fatal disorder caused by abnormal and nonfunctional connections between veins and arteries in the myometrium. It's consistently related to uterine trauma or prior pregnancy. A 32-year-old patient presented with severe vaginal bleeding as well as a 30-day history of abnormal vaginal bleeding. She was diagnosed with UAVM by transabdominal ultrasound color Doppler. MRI confirmed the diagnosis of UAVM. Therefore, she was given oral progesterone 5 mg three times a day for 21 days as a conservative treatment. She was followed for a year, remained asymptomatic and conceived spontaneously, and had a low-risk pregnancy, with good maternal and fetal outcomes. Since the treatment, the patient has not suffered any serious uterine hemorrhage.
