{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.<BR>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.<BR>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.<BR>Ethanol embolotherapy was a less invasive, more precise, and quick-action approach managing AVM of the jaw and related emergency medicine.
