This is a 65-year-old patient who has been on hemodialysis for 5 years with a left humeral-basilic arteriovenous fistula. This fistula is currently in hyper flow estimated at 2300 ml/min associated with three uncomplicated false-aneurysms. There was no thrombosis in the arteries and veins of the upper limb. In order to perform another replacement fistula on the right upper limb, the patient was referred to us for vascular mapping of the right upper limb. This vascular mapping was not favorable to the realization of a native arteriovenous fistula, due to the insufficient caliber of the superficial veins. In addition, exploration of the neck vessels revealed a left jugular thrombosis. The thrombus was hypoechoic oval, measuring 32x8x12mm, floating in the lumen of the internal jugular vein without parietal contact and giving the appearance of a "floating boat" in longitudinal view (A,B). The patient had no other signs of thrombosis and received anticoagulant therapy to prevent the occurrence of another thromboembolic event that could be more deleterious. This case illustrates the importance of scanning the neck vessels during upper extremity vessel ultrasound to look for any abnormalities at this level.
