RATIONALE: Uterine arteriovenous fistula (UAVF) is a rare vascular abnormality that can cause severe and potentially life-threatening hemorrhage. Uterine artery embolization is a common treatment that may affect ovarian and uterine perfusion and cause fertility problems. We herein report our experience treating 2 patients with UAVF who underwent resection after temporary occlusion of both internal iliac arteries.
PATIENT CONCERNS: Both patients presented with a large UAVF after incomplete miscarriages in the second trimester. Magnetic resonance imaging revealed a UAVF measuring 3.6 × 2.6 × 2.1 cm over the myometrium of the posterior uterine in case 1, and a UAVF of 7.1 × 4.1 × 4.5 cm was identified in case 2.
DIAGNOSIS: Uterine arteriovenous fistula, retained products of conception.
INTERVENTIONS: The patients underwent resection of UAVF with temporary occlusion of the internal iliac arteries and hysteroscopic removal of the retained products of conception.
OUTCOMES: Intraoperative bleeding were minimal. Neither patient exhibited abnormal uterine bleeding at the 6-month follow-up. Follow-up ultrasonography and magnetic resonance imaging showed normal uterine myometrium and endometrium and no residual disease.
LESSONS: UAVF resection after temporary occlusion of the internal iliac arteries is a promising treatment approach for UAVF. This technique can reduce intraoperative bleeding and remove the potential hemorrhage-related lesion while preserving fertility.
