A long-term central venous catheter (CVC) for dialysis — a bridge when no fistula exists, with higher infection risk.
Tunneled catheters (e.g., Tesio, Permcath) are placed in the internal jugular vein with a subcutaneous tunnel. They are used while a fistula matures or after access failure — 'catheter-last' is the guideline principle. Catheter dysfunction and bloodstream infection are the main complications; cuff and exit-site care are critical.
The surgical connection created to allow blood to flow between the patient's circulatory system and the dialysis machine during hemodialysis sessions.
A flexible tube inserted into a large central vein (usually internal jugular) to provide temporary or permanent vascular access for hemodialysis when AV fistula or graft is unavailable.
Bloodstream infection originating from a dialysis catheter — a major preventable cause of hospitalization and death.
A medical procedure that filters waste products, excess fluids, and toxins from the blood using a dialysis machine when the kidneys can no longer perform this function adequately.
