Abstract: The article reports a rare case of isolated persistent left superior vena cava (PLSVC) found during the catheterization of a dialysis catheter in an end-stage renal disease patient and the occurrence of guidewire entrapment in Chiari net. The patient was scheduled to have emergency dialysis due to end-stage renal disease and acute left heart failure. And a tunnel-cuffed catheter (TCC) for dialysis insertion was planned. Isolated PLSVC was found firstly by the imaging process. Then the guidewire was entrapped at the right atrium in the further operation. During the operation of the guidewire, the guidewire loosened and withdrawn with a fine fiber, which was considered a possibility of Chiari net. In the follow-up after one week, the TCC worked well, and the heart function improved after dialysis.
