Hemodialysis (HD) remains the primary renal replacement therapy for over 80% of global end-stage kidney disease (ESKD) patients, underscoring the critical need for safe and effective vascular access. Despite the high complication rates and associated morbidity/mortality of tunneled cuffed catheters (TCCs), their use remains prevalent, particularly in aging populations. We present a case where a fractured TCC fragment migrated into the superior vena cava (SVC) during catheter exchange. The fragment was successfully retrieved using a snare device with single-sheath traction wire technique, followed by in situ TCC replacement.
