What is Tunneled Hemodialysis Catheter Placement?
This procedure involves placing a flexible tube (catheter) into a large vein—usually in the chest or neck—to provide access for hemodialysis. The catheter is “tunneled” under the skin before entering the vein, which helps reduce the risk of infection and allows it to remain in place for long-term use.
This procedure helps to:
- Provide immediate vascular access for hemodialysis
- Serve as a temporary or long-term solution when fistulas or grafts are not available
- Enable efficient blood flow for dialysis treatments
- Maintain stable access for patients awaiting permanent access creation
- Support ongoing treatment in patients with chronic kidney disease
What to expect during the procedure?
- Performed under local anesthesia and mild sedation
- A small incision is made near the collarbone or chest area
- The catheter is guided into a central vein using imaging (ultrasound or X-ray)
- The external portion of the catheter exits through a small tunnel in the skin
- The procedure usually takes 30–60 minutes
- Patients can typically go home the same day after observation
