Method of salvaging long-term dialysis catheters

Area of Science:

• Nephrology
• Vascular Access
• Medical Device Technology

Background:

• Hemodialysis is a critical renal replacement therapy often utilizing indwelling venous catheters.
• Catheter malfunction is a common complication, typically managed with urokinase or catheter stripping.
• Difficult vascular access presents challenges for effective hemodialysis treatment.

Purpose of the Study:

• To describe a novel, simple technique for salvaging malfunctioning indwelling hemodialysis catheters.
• To evaluate the efficacy of repositioning a dialysis catheter within a subcutaneous tunnel for flow restoration.
• To assess the safety of this technique regarding tunnel infection and catheter-related sepsis.

Main Methods:

• A straightforward technique involving repositioning the indwelling dialysis catheter into a subcutaneous tunnel was applied.
• The procedure was performed following catheter manipulation to address flow problems.
• Outcomes were assessed for restored catheter function and absence of complications.

Main Results:

• Successful restoration of function was achieved in all treated hemodialysis catheters.
• No instances of tunnel infection were observed post-procedure.
• No cases of catheter-related sepsis were reported.

Conclusions:

• The described technique offers an effective method for salvaging malfunctioning hemodialysis catheters.
• This approach is particularly beneficial for patients with difficult vascular access.
• The technique demonstrates safety by preventing tunnel infections and sepsis.
