Multimodality imaging and transcatheter coil embolization of an iatrogenic subclavian artery-internal jugular vein fistula.

A 69-year-old man was found to have a loud continuous bruit in the neck. Duplex carotid ultrasound showed high-velocity turbulent flow in the dilated and pulsatile right internal jugular vein. Computed tomography angiogram demonstrated markedly enlarged right internal jugular vein with a posteriorly located arteriovenous communication.
