Differential Diagnosis and Treatment of Suspected Uterine Arteriovenous Fistula or Pregnancy Residue after Abortion

Uterine arteriovenous fistula (UAVF) belongs to uterine vascular disease, which refers to the abnormal direct traffic between uterine artery branches and vein branches by passing the capillary network. The acquired UAVF is often secondary to uterine trauma. Due to the certain similarity in the B-ultrasound manifestations between pregnancy residue after abortion and UAVF, the accuracy of diagnosis may be interfered. A case of mixed mass of left posterior wall of uterus with extremely rich blood flow signals and suspected UAVF was reported. After oral short-acting contraceptive, hysteroscopic surgery was performed, and the pregnancy residue was diagnosed. Combined with literature review, this case report provided us more experience for the differential diagnosis, treatment and prevention of pregnancy residue after abortion and UAVF.
