Arteriovenous malformations (AVMs) of the jaws are extremely rare lesions, which are probably hamartomas of developmental malformations. In this article we present an extremely high-flow AVM of the lower jaw with exsanguinating bleeding from the socket of the exfoliated tooth. Repeated episodic bleedings were controlled with local pressure and packing. Digital subtraction angiography revealed a high-flow, high-shunt AVM. Preoperative embolization and external carotid artery ligation, dental extraction, curettage and packing with Gelfoam were done. Postoperative bleeding stopped, bruit ceased, and it had disappeared completely after 6 months follow-up. On the second follow-up visit, 3 months later, the patient was found to have no problems.
颌骨动静脉畸形（AVM）是极为罕见的病变，可能是发育畸形的错构瘤。在本文中，我们呈现了一例下颌骨极高流量的AVM，伴有脱落牙齿牙槽窝的大量出血。通过局部压迫和填塞控制了反复的间歇性出血。数字减影血管造影显示为高流量、高分流的AVM。进行了术前栓塞和颈外动脉结扎、拔牙、刮除术并用明胶海绵填塞。术后出血停止，杂音消失，随访6个月后完全消失。在3个月后的第二次随访中，发现患者没有问题。
