How a Fistula for Dialysis Can Be Created Without Cuts or Scars

If you’re about to start dialysis, you’ve probably heard of something called an arteriovenous (AV) fistula. This is a special connection between an artery and a vein in your arm. It allows doctors to safely and easily access your blood for dialysis treatments.

In the past, creating a fistula required surgery. But today, there’s a new, less invasive way to do it—with no cuts or stitches.

What Is an AV Fistula?

An AV fistula connects an artery to a vein. This gives your vein higher blood flow, which helps it grow stronger and thicker. Over time, it becomes easier to access for dialysis.

There are other options like catheters or grafts, but they come with more risks. Catheters can get infected and damage your veins. Grafts are made from synthetic materials and don’t last as long.

That’s why a native AV fistula—made from your own blood vessels—is considered the best long-term option.

The Problem With Traditional Surgery

Surgical fistula creation means making an incision, cleaning the vein, and stitching it to the artery. Even though it’s a small surgery, it can be tough for patients with kidney disease who may have trouble healing. There are also risks like nerve damage, bleeding, and infection.

The New Option: Percutaneous AV Fistula

Thanks to new technology, we can now create a fistula without surgery. This method is called a percutaneous AV fistula. That means the fistula is created through a needle puncture—no cuts, no stitches, and a faster recovery.

There are two FDA-approved systems for this:

1. Ellipsys System

  • Uses a single needle puncture.
  • Guided by ultrasound.
  • A device uses heat and pressure to connect the artery and vein.

2. WavelinQ System

  • Uses two small punctures—one in the artery and one in the vein.
  • Tiny magnets bring the artery and vein together.
  • Radiofrequency energy creates the connection.

Both methods can be done in under 30 minutes and usually with light sedation. Most patients go home the same day.

After the Procedure

  • Mild soreness and bruising are normal.
  • You might feel a light vibration (called a “thrill”) in your arm.
  • Hand exercises can help the vein grow faster.
  • A second procedure may be done in a few weeks to help the fistula mature.

The goal is to reach at least 700 ml/min of blood flow, which is enough for dialysis. If it doesn’t mature, your doctor may recommend other options like surgery or a graft.

Is This Right for You?

To qualify, your veins and arteries need to be big enough—usually 2–3 mm. An ultrasound of your arm will help us decide.

“Percutaneous AV fistulas are a big step forward in dialysis care. They’re safer, less invasive, and can offer better long-term results.”
—Dr. Fabio Komlos, Interventional Radiologist

Final Thoughts

If you need dialysis, ask your doctor if a percutaneous AV fistula is right for you. It’s a safer, faster, and more comfortable option for many patients.
