Arteriovenous malformations are extremely rare conditions in that can result from abnormalities in the structure of blood vessels, which may be potentially fatal. A 30-year-old female patient visited our hospital with a complaint of swelling on the right maxillary posterior gingiva along with the large port-wine stain on right side of face. On clinical examination, the swelling was compressible and pulsatile. Radiographic examination revealed a lytic lesion of maxilla. Diagnostic angiography revealed a high-flow arteriovenous malformation of maxilla which was treated by selective transarterial embolization of maxillary artery using polyvinyl alcohol particles.
动静脉畸形是极为罕见的病症，可由血管结构异常导致，可能具有潜在致命性。一名30岁女性患者因右侧上颌后牙龈肿胀及右侧面部大片葡萄酒色斑就诊于我院。临床检查发现，肿胀可压缩且有搏动。影像学检查显示上颌有溶骨性病变。诊断性血管造影显示上颌高流量动静脉畸形，采用聚乙烯醇颗粒对上颌动脉进行选择性经动脉栓塞治疗。
