超選択的液体塞栓術施行後摘出した下顎骨中心性血管腫の1例

抄録

We report a case of a life-threatening central hemangioma of the mandible treated with superselective new liquid embolization technique prior to excision. A 24-yearold woman was referred by her dentist for severe hemorrhage from the buccal gingiva of the mandibular left molar region. Angiography showed a vascular lesion mostly fed by the inferior alveolar artery. Five days prior to surgery, superselective embolization was carried out using estrogen alcohol and polyvinyl acetate, which is a newly developed method. Histopathological study showed a cavernous hemangioma of the mandibular region undergoing bone destruction with complete obliteration of large vessels and small arterioles without any signs of hemorrhage. This superselective liquid embolization technique can provide a good modality for the treatment of vascular lesions of the oral and maxillofacial areas.
