Treatment of uterine arteriovenous malformation by myometrial lesion resection combined with artery occlusion under laparoscopy: a case report and literature review

Uterine arteriovenous malformation (AVM) is an uncommon, potentially life-threatening condition, and the primary therapeutic method is embolization. We describe a case of a 36-year-old woman with acquired uterine AVM accompanied by abnormal vaginal bleeding. The diagnosis was established by Doppler flow ultrasonography combined with magnetic resonance arteriography. Because this uterine AVM was extensive and multiple, uterine arterial embolization could not be considered. We therefore employed a combined method under laparoscopy, in which the uterine arteries were first occluded, then uterine myometrial lesions were resected and abnormal pelvic blood vessels were ablated. Finally, the uterus was reconstructed with an intact uterine cavity. Abnormal vaginal bleeding was successfully stopped after operation, but amenorrhea due to uterine adhesions occurred. This method is suitable for the treatment of uterine AVM with extensive and multiple lesions, but it should be chosen cautiously for women of reproductive age with AVM and fertility requirement.
