A congenital external carotid artery-external jugular vein arteriovenous fistula was successfully treated by coil embolization (case report and literature review).

ABSTRACT

OBJECT Congenital arteriovenous fistula involving the external carotid system is rare. METHODS: This paper reports a case of congenital external carotid artery-external jugular vein arteriovenous fistula admitted to Xuanwu Hospital, and reviews the literature. RESULTS: The patient was a boy, 9 years old, with a history of pulsatile mass and thrill in the right neck since his birth. External carotid artery-external jugular vein fistula was confirmed by the digital subtraction angio-graphy. And coil embolization was done later. Postoperative immediate angiography confirmed the complete occlusion of the fistula, and partial branch of the external carotid artery can be seen. The abnormal clinical manifestation disappeared after the procedure without any complications. CONCLUSION: This case and relevant literatures remind us that congenital external carotid artery-external jugular vein arteriovenous fistula has its unique features, and it can be treated by coil embolization safely and effectively.
