Abstract：
Mandibular arteriovenous malformation (AVM) is rare. Our work aims to introduce the ethanol embolization of a patient suffering from acute oral hemorrhage induced by mandibular AVM.
A 35-year-old woman without coagulopathy underwent tooth extraction, and the acute oral bleeding occurred intraoperatively. Imaging examinations indicated the enhancement of vascular mass with bone destruction inside the mandible. Angiography finally confirmed the high blood flow nature and the diagnosis of AVM.
During the interventional procedure, the coils were first applied into the dilated outflowing vein to slow down the blood flow rate of mandibular AVM. Absolute ethanol was injected in a multi-bolus modality to destroy the nidus of AVM. Her mandibular lesion had been stable in the 12-month re-examined angiography, no further bleeding occurred during the period.
Ethanol embolotherapy was a less invasive, more precise, and quick-action approach managing AVM of the jaw and related emergency medicine.

摘要：
背景：下颌动静脉畸形（AVM）很少见。我们的工作旨在介绍下颌AVM引起的急性口腔出血患者的乙醇栓塞。
方法：一名35岁无凝血障碍的妇女接受了拔牙治疗，术中发生急性口腔出血。影像学检查显示血管块增强，下颌骨内部骨破坏。血管造影最终证实了高血流性质和AVM的诊断。
结果：在介入过程中，首先将线圈施加到扩张的流出静脉中，以减慢下颌AVM的血流速度。以多推注方式注入无水乙醇以破坏AVM的nidus。在12个月的血管造影复查中，她的下颌骨病变稳定，期间无进一步出血.
结论：乙醇栓塞治疗是一种侵入性较小的，更精确,和快速行动方法管理下颌的AVM和相关的急诊医学。
