Thrombus formation has been reported to occur relatively early after the insertion of non-cuffed hemodialysis catheters(NCCs). Complications arising from thrombus formation include the risk of catheter dysfunction, such as inadequate de-bleeding, pulmonary thromboembolism, severe catheter-related bloodstream infection, and vascular stenosis or occlusion. This study focused on patients who underwent ultrasonography at the time of NCC removal among those who underwent blood purification using NCCs at our center. NCCs were inserted into the right internal jugular vein in 14 patients and into the left internal jugular vein in five patients. The median(IQR)duration of NCC placement was 7(6-11)days. A high frequency of thrombus formation was observed in 17 of 19 patients(89.5%). NCCs are often utilized in emergencies when blood purification is required. However, it should be noted that a high percentage of thrombi forms in the insertion vessel during blood purification.
