Tunneled Hemodialysis Catheter (Permcath)

A Safe, Long-Term Vascular Access for Dialysis

People with kidney failure often need hemodialysis to clean their blood. For dialysis to work, doctors need a reliable way to access your blood vessels.
A tunneled hemodialysis catheter is a soft, flexible tube placed under the skin into a large vein (usually in the neck or chest) that allows safe and repeated dialysis treatments—especially when a fistula or graft is not ready or not possible.

👉Need urgent or long-term dialysis access?

What Is a Tunneled Hemodialysis Catheter?

A tunneled hemodialysis catheter is:

  • A special double-lumen tube placed into a large central vein (usually the neck or chest)
  • The catheter is tunneled under the skin before entering the vein
  • It has a small cuff under the skin that helps prevent infection and keep it in place
  • One end stays inside the vein, and the other end stays outside the body for dialysis connection

It is used for:

  • Regular hemodialysis sessions
  • Medium- to long-term dialysis access
  • Patients who cannot use a fistula or graft immediately
  • Reliable dialysis access

  • Can be used soon after placement

  • More secure and longer-lasting than temporary catheters

Why Is a Tunneled Hemodialysis Catheter Done?

This catheter is placed when:

  • You need urgent dialysis and a fistula/graft is not ready yet
  • You are waiting for a fistula or graft to mature
  • You are not suitable for fistula or graft surgery
  • Your previous dialysis access has failed
  • You need long-term but non-permanent dialysis access

Main goals:

  • Provide safe and reliable access for dialysis
  • Avoid repeated needle pricks
  • Ensure effective blood cleaning during dialysis
  • Improve comfort and continuity of treatment

How Is Tunneled Hemodialysis Catheter Insertion Done?

The procedure is performed by a trained specialist (often an interventional radiologist or surgeon) using ultrasound and X-ray guidance.

Step-by-step:

  • You lie comfortably; local anesthesia and sometimes mild sedation are given
  • The doctor cleans and numbs the skin
  • Using ultrasound, a vein in the neck or chest is safely accessed
  • The catheter is tunneled under the skin and then placed into the vein
  • X-ray is used to confirm correct position
  • The catheter is secured and covered with a sterile dressing

The catheter can usually be used for dialysis within 24 hours (sometimes even earlier, depending on the type).

What Are the Risks?

Tunneled hemodialysis catheter placement is generally safe, but like any procedure, it has some risks. Approximate incidence includes:

  • Pain or bruising at insertion site – common (10–20%)
  • Bleeding or hematoma – uncommon (<3–5%)
  • Infection at skin or catheter site – uncommon (5–10% over time)
  • Bloodstream infection (catheter-related) – uncommon (2–5% per year)
  • Catheter blockage or poor flow – uncommon (5–15%)
  • Catheter displacement or damage – uncommon (<5%)
  • Air embolism or vein injury – rare (<1%)
  • Pneumothorax (air around lung, if neck/chest vein used) – rare (<1–2%)

What Are the Alternatives?

Your dialysis access options depend on:

  • How soon you need dialysis
  • Whether you need short-term or long-term dialysis access
  • The condition of your blood vessels and overall health

Your nephrologist and interventional radiologist will help you choose the best option.

Alternative 1: No Dialysis Catheter or Access

  • Avoids placing a tunneled catheter or any access device
  • Major risk: if you need dialysis and have no other access, your health can worsen quickly and can become life-threatening
  • Not a safe option if dialysis is urgently required

Alternative 2: Permanent Hemodialysis Access (AV Fistula or AV Graft)

  • Best for patients who need long-term hemodialysis
  • Two main types:
    • Arteriovenous (AV) fistula – a natural connection between an artery and a vein
    • Arteriovenous (AV) graft – uses a synthetic tube to connect an artery and a vein
  • Both require surgery, usually in the arm
  • Provide more durable and reliable access than catheters
  • Have a lower long-term infection risk compared to tunneled catheters
  • Need time to mature before they can be used for dialysis

Alternative 3: Peritoneal Dialysis

  • A soft tube is placed into the abdomen (belly)
  • Special dialysis fluid is put in and then drained out to clean the blood
  • Can often be done at home
  • Not suitable for all patients and requires training and strict hygiene

Choosing the Right Dialysis Access

A tunneled hemodialysis catheter provides quick, reliable access for dialysis when treatment is needed urgently or while waiting for a fistula or graft to mature. A personalized evaluation ensures the safest and most effective dialysis access plan.

📌 Whenever possible, a fistula or graft is preferred for long-term dialysis, but tunneled catheters are very useful when those are not ready or not possible.

What Happens After Your Procedure?

After catheter placement:

  • You will have a small dressing over the site
  • Mild pain or soreness may last 1–2 days
  • You can usually go home the same day
  • The catheter site must be kept clean and dry
  • Dialysis staff will use the catheter for your treatments
  • You will be taught:
    • How to protect the catheter
    • How to watch for signs of infection (redness, pain, fever, discharge)
  • Regular follow-up helps prevent complications
  • The catheter can be removed later when a fistula or graft is ready

Frequently Asked Questions (FAQs) – Tunneled Hemodialysis Catheter

A transjugular liver biopsy is a minimally invasive procedure where a small sample of liver tissue is taken through a vein in the neck, making it safer for patients who have a high risk of bleeding or ascites.

It is used when a patient:

  • Needs urgent dialysis
  • Is waiting for a fistula or graft to mature
  • Cannot have a fistula or graft
  • Has a failed dialysis access
  • Needs medium- to long-term dialysis access

No. It is usually a temporary or medium-term solution until a fistula or graft is ready, though in some patients it may be used longer.

A tunneled catheter:

  • Is placed under the skin before entering the vein
  • Has a cuff to reduce infection risk
  • Is more stable and safer for longer use than temporary catheters

The procedure is done under local anesthesia, so most patients feel only mild discomfort.

The procedure usually takes 30 to 45 minutes.

In many cases, yes. It can often be used within 24 hours, and sometimes even the same day.

It can stay for several months or longer, as long as it works well and there is no infection or blockage.

Possible risks include infection, bleeding, bruising, catheter blockage, poor blood flow, or rarely lung or vein injury. Serious complications are uncommon.

  • Keep the area clean and dry
  • Do not pull or twist the catheter
  • Follow dressing change instructions
  • Watch for signs of infection like redness, pain, swelling, or fever

You can usually shower with precautions, but the catheter site must be kept dry and protected. Your dialysis team will guide you.

  • Redness, pain, or swelling at the site
  • Discharge or pus
  • Fever or chills
  • Feeling unwell after dialysis

It is safe and widely used, but AV fistula or graft is usually better for long-term dialysis because they have lower infection risk.

It is usually inserted by a trained interventional radiologist, vascular surgeon, or surgeon using ultrasound and X-ray guidance.

Yes. It is available in most hospitals and dialysis centers across India.
