Intravascular embolization of a congenital subclavian arteriovenous fistula.

Congenital subclavian arteriovenous fistula (AVF) is an extremely rare entity, only one case has been documented previously [1]. In general , subclavian AVFs present with a bruit, thrill, or mass lesion [2-4]. However, unusual cases can present with intracranial hypertension or congestive heart failure [1, 5]. The presentation in our patient, with venous hypertension in the head and neck, is extremely unusual and partially due to previous surgical ligation. In this case, intravascular embolization was used to successfully treat this lesion.
