Abstract: Objective: To analyze the cause and clinical manifestations of uterus arteriovenous malformations (UAVMs), and to discuss the precautions in diagnosis and treatment. Methods：Five patients (accepted from March 2014 to March 2018) were diagnosed as UAVMs by Peking University Third Hospital. The clinical data were retrospectively analyzed. Results：UAVMs were preliminarily diagnosed by ultrasound Doppler examination in five cases. One was treated with hysteroscopic curettage plus uterine balloon oppression, and the lesion disappeared 3 months later. One was treated with the ultrasound-guided curettage, and the lesion also disappeared after 3 months. Three other cases were confirmed by angiography, and treated synchronously with the selective uterine artery embolization. One patient delivered successfully after 2+ years. One had amenorrhea after 2 months. The last case had curettage after embolization, and the lesion disappeared 3 months after operation. Conclusions：Color doppler ultrasound through vagina can be adopted as the preferred examination of UAVMs, while angiography remains the golden criteria for diagnosis. Selective uterine artery embolization is an effective treatment of UAVMs.
