耳介巨大化を伴った耳介動静脈奇形例

抄録

A 22-year-old male visited our outpatient clinic with a complaint of bleeding from the left auricle. The left auricle measured 80 by 50mm and the right 55 by 35mm. Engorgement vessels with pulsation was noted inside the helix and in the upper half of the auricle. CTscan, MRI, thermographic examination and angiography were performed, and arteriovenous malformation of the auricle was diagnosed. The main feeding arteries were the superficial temporal artery and the posterior auricular artery, as demonstrated by angiography via the left external carotid artery. Lingation of the superficial temporal artery and the posterior auricular artery was performed under local anesthesia. After a relapse, lingation of the external carotid artery was performed under general anesthesia. The post-operative course was good, and pulsation in the helix disappeared. Two months after surgery, plastic surgery of the left auricle was performed at the patient's request.
