A dialysis catheter is a thin, sterile tube that allows blood to be removed from the body and purified by the dialysis machine in patients with kidney failure undergoing hemodialysis.
This catheter connects the dialysis machine to the vascular system. It is typically placed in the neck (jugular vein), chest (subclavian vein), or groin (femoral vein).
The catheter is used as an emergency or temporary solution in patients where vascular access is difficult or who cannot yet undergo fistula surgery.

1. What is a Dialysis Catheter (Hemodialysis Catheter)?

A dialysis catheter is a thin, sterile tube that allows blood to be removed from the body and purified by the dialysis machine in patients with kidney failure undergoing hemodialysis.
This catheter connects the dialysis machine to the vascular system. It is typically placed in the neck (jugular vein), chest (subclavian vein), or groin (femoral vein).
The catheter is used as an emergency or temporary solution in patients where vascular access is difficult or who cannot yet undergo fistula surgery.

2. In what situations is a dialysis catheter used?

A dialysis catheter is generally preferred in the following situations:

• In patients with chronic renal failure who need urgent dialysis,
• In patients with acute renal failure or sudden kidney failure
, • In patients with fistula maturation expected,
• In cases where fistula or graft occlusion has developed,
• In people with unsuitable vascular structure,
• In patients with acute renal failure who need temporary dialysis.

A catheter is one of the most important tools for vascular access, especially in hemodialysis treatment.
The goal is to establish vascular access that provides safe and adequate blood flow. This ensures efficient dialysis sessions and maximizes patient safety.

3. Dialysis Catheter Types

➤ Where and How is a Temporary Dialysis Catheter Inserted?
A temporary dialysis catheter is for short-term use.
It is usually inserted into the jugular or femoral vein under local anesthesia.
The procedure takes approximately 10–20 minutes.
This catheter, inserted under sterile conditions, can be used for several days to several weeks.
It is easy to insert, but the risk of infection is higher than with permanent catheters.

➤ Where and How is a Permanent Dialysis Catheter Inserted?
• A permanent dialysis catheter (tunneled catheter) is preferred for long-term dialysis treatments.
This catheter is inserted through the neck or chest wall and directed into the main vein.
The tunneled portion, placed under the skin, reduces the risk of infection.
Once inserted, it can be used safely for months or years. It is used in patients who cannot have a fistula or whose vascular structure is unsuitable.

Which Type Should You Choose?
The decision is made by the specialist based on the patient's vascular condition, treatment duration, and previous interventions.
A permanent dialysis catheter is more advantageous for long-term treatments.

4. How is a Dialysis Catheter Inserted?

Dialysis catheter insertion is performed by interventional radiologists in a sterile environment and usually under ultrasound guidance.

1. The patient is placed in the appropriate position.

2. The area is cleaned with antiseptic solution.

3. Local anesthesia is applied.

4. The vein is entered with a needle and a guide wire is placed.

5. The catheter is advanced and fixed into the correct position.

6. The dressing is applied and position confirmation is provided by x-ray.

7. The procedure is completed by testing blood flow through the catheter.

The procedure takes approximately 20–60 minutes. Same-day discharge is usually possible.

5. In which department and who inserts the dialysis catheter?

Dialysis catheter insertion is performed by the Interventional Radiology Department in hospitals.
This unit visualizes the vascular access with X-ray and ultrasound to ensure safe placement of the catheter in the most appropriate location.
Magnet Hospital's Interventional Radiology team, staffed by experienced physicians, prioritizes patient safety.

6. Where is the dialysis catheter attached?

The catheter is usually inserted in the following areas:

• Neck (jugular vein)
• Chest (subclavian vein)
• Groin (femoral vein)

The choice is made according to the patient's vascular structure, current medical condition and duration of treatment.

7. Dialysis Catheter Risks

As with any medical procedure, dialysis catheters carry some risks:

• Infection
• Bleeding or hematoma formation
• Vascular occlusion
• Catheter dislodgement
• Thrombosis (clot formation)

However, these risks are minimal when the procedure is performed under sterile conditions and by experienced teams.

8. How Long Does It Take to Insert a Dialysis Catheter?

Although it varies depending on the type of catheter:

• Temporary catheter: Approximately 10–20 minutes,
• Permanent catheter: Approximately 30–45 minutes.

After the procedure, the patient is kept under observation for a short time.

9. What Should Be Considered After Dialysis Catheter Insertion?

• The catheter site should be kept clean, dry, and covered.
• The catheter line should not be pulled, kinked, or forced.
• The dressing should be changed after dialysis.
• A physician should be consulted in case of pain, redness, fever, or discharge.
• Pressure should not be applied to the area where the catheter is attached.

These precautions greatly reduce the risk of dialysis catheter infection.

10. Dialysis Catheter Infection Symptoms

Symptoms of catheter infection include:

• Redness or swelling around the catheter,
• Discharge or foul odor,
• Fever, chills,
• Pain or burning sensation during dialysis.

In these cases, a doctor or dialysis center should be consulted immediately.

11. Dialysis Catheter Care and Cleaning Recommendations

• The area around the catheter should be checked daily and cleaned with a sterile method.
• Hands should be washed and disinfected.
• Regular heparin flushes are administered to prevent blood clots or blockages in the catheter line.
• The catheter dressing should be changed after each dialysis session.
• If the skin around the catheter becomes red or tender, infection is suspected.

Regular maintenance extends catheter life and increases patient comfort.

12. Dialysis Catheter Blockage and Infection Risk

12.1. Causes of Clogging:

• Blood clot formation
• Catheter tip sticking to the vessel wall
• Catheter displacement or kinking
• Pressure imbalance or backflow problem

Symptoms include low flow, alarms, or increased pressure during dialysis.
Treatment includes heparin flush, thrombolytic therapy, or catheter exchange if necessary.

12.2. Symptoms of Infection:

• Fever, chills
• Redness, discharge, pain around the catheter
• Chills during dialysis

In this case, a catheter culture may be taken, antibiotics may be started, or the catheter may be removed.
Hygiene and regular care significantly reduce the risk of infection.

13. What to do if dialysis cannot be performed through the dialysis catheter?

• The catheter position is checked (with ultrasound or fluoroscopy).
• If there is a blockage or clot (thrombolytic therapy), the catheter is flushed.
• If the flow problem persists, interventional radiology evaluation is required.
• If necessary, the catheter is changed or fistula opening is planned.

Such situations can usually be resolved quickly, but timely intervention is crucial.

14. How to Remove a Dialysis Catheter?

Catheter removal is also performed by interventional radiology.
It's completed quickly under local anesthesia and sterile conditions.
After the procedure, a dressing is applied, and the area is kept closed for a period of time.

15. Long-Term Catheter Use and Change Process

• Indwelling catheters can be used for months, 6 months to 2 years, but they should be checked regularly.
• When the catheter's function decreases or it becomes infected, it is replaced with a new one.
• In the long term, natural vascular access such as an arteriovenous fistula (AVF) is preferred.
• In daily life, it is important to protect the catheter site and avoid contact with water.
