A mandibular arteriovenous malformation (AVM) is rare, and unawareness of this condition can lead to catastrophic complications. Embolization is an effective means to treat these lesions. The osseous changes and long-term outcomes among the pediatric patients after embolization treatment remain unclear. We present a 6-year-old patient with mandibular arteriovenous malformation who had sustained hemorrhagic shock after a tooth extraction. She was referred to us after stabilization of the hemodynamic condition. The patient received transarterial and direct intralesional embolization. Local infection occurred 3 months after embolization, but was well controlled. Serial computed tomography and panoramic radiographs were performed during follow-up examinations. The imaging studies showed gradual obliteration of the vascular space followed by normal bone regeneration and remodeling. The processes were complete during a period of 2 years. There was no recurrence of the vascular malformation and no abnormal growth of the right side of the mandible after 4 years and 4 months of observation.
下颌动静脉畸形（AVM）较为罕见，对这种疾病缺乏认识可能会导致灾难性并发症。栓塞是治疗这些病变的有效方法。栓塞治疗后儿科患者的骨质变化和长期预后仍不明确。我们报告一名6岁的下颌动静脉畸形患者，其拔牙后发生失血性休克。在血流动力学状况稳定后，她被转诊至我们这里。该患者接受了经动脉和直接瘤内栓塞治疗。栓塞后3个月发生局部感染，但得到了很好的控制。随访检查期间进行了系列计算机断层扫描和全景X线片检查。影像学研究显示血管腔逐渐闭塞，随后是正常的骨再生和重塑。这些过程在2年内完成。观察4年4个月后，血管畸形无复发，下颌骨右侧无异常生长。
