Renal replacement therapy (RRT) remains a cornerstone for the management of patients with severe acute kidney injury (AKI). The efficacy of RRT depends on a reliable vascular access.

In critically ill patients, continuous renal replacement therapy (CRRT) is usually performed with a temporary dialysis catheter (TDC), which can be employed in any patient, easily inserted at the bedside, and used immediately after insertion. Malfunction of the catheter is frequently due to insufficient blood flow rates, repeated clotting of the extracorporeal circuit, and shortened dialysis time.
