Japanese Journal of Oral Maxillofacial Surgery(2017)
摘要
The present report describes our experience treating a patient who had an arteriovenous malformation (AVM) discovered because of abnormal bleeding during tooth extraction. The patient was a 35-year-old man who underwent extraction of the lower left third molar tooth, which was horizontally impacted. During extraction, abnormal bleeding occurred, and the patient he was transferred to our hospital because the bleeding could not be controlled. Contrast-enhanced computed tomography (CT) and 3-dimensional CT angiography revealed an AVM inside the left mandible. Transvenous embolization was performed. There was no further abnormal bleeding, the postoperative course was good, and the patient was discharged. Two months later, follow-up angiography was performed, and AVM resolution was confirmed.
