이하선 종물을 주소로 내원한 외상성 외경동맥-내경정맥 루 1예

An arteriovenous fistula represents an abnormal communication and consists of an endothelial-lined communication between an artery and vein. Its most common cause is trauma. Superficial temporal artery was involved most often, followed by facial artery, occipital artery. But external carotid artery is rare. Frequent presenting symptom is pulsating mass, pulsating tinnitus, thrill and so on. The symptoms were related to fistula site and venous drainage. Confirmative diagnosis was angiography and treatment was surgery or interventional radiology. Excision of the fistula has been the preferred method for surgical management of these lesion however, this is not always possible because the fistula may be surgically inaccessible and excessive blood loss causing by high blood flow. Recently, with advent of transcatheter interventional techniques and new embolic agents, embolization has increased popular. We experienced that a case of infraauricular pulsating mass and tinnitus due to external carotid artery-internal jugular vein fistula was obliterated by embolization of interventional radiology.
