A Central Venous Catheter Line Misadventure “Doctor why do I have a humming sound in my ear?”

Abstract

We report a 32-year-old female patient who was referred to a tertiary care hospital in Muscat, Oman, in 2021 with an iatrogenic arteriovenous fistula (AVF) that presented as a neck swelling which developed few weeks after an attempt of central venous catheterisation through the right internal jugular vein. The fistula was corrected surgically with a successful outcome. AVF is an abnormal communication between an artery and vein which can occur as a congenital anomaly, after trauma or iatrogenic following central venous catheter or endovenous thermal ablation.
