What Is a Percutaneous AV Fistula? A Modern Solution for Dialysis Access
If you’ve recently been told you need an arteriovenous (AV) fistula for dialysis, you might be wondering what your options are—and whether surgery is the only path forward. Fortunately, advances in vascular care have introduced a minimally invasive alternative: the percutaneous AV fistula, also known as an endoAVF.
What Is an AV Fistula?
An AV fistula is a connection made between an artery and a vein. It’s used in patients with kidney failure who need regular hemodialysis. The fistula allows for repeated access to the bloodstream, making dialysis more effective and safer over time. Traditionally, AV fistulas have been created using open surgery.
What Is a Percutaneous AV Fistula?
A percutaneous AV fistula is created without open surgery. Using advanced imaging guidance, an interventional radiologist or vascular specialist accesses the artery and vein through a tiny skin puncture and uses specialized devices to create the fistula inside the body. No surgical incision is required.
How Is It Done?
The procedure is typically done in an outpatient setting under local anesthesia with mild sedation. A catheter is inserted into a vein in the arm, and using ultrasound and X-ray guidance, the artery and vein are joined using heat or mechanical energy. The two most common systems used are:
- Ellipsys System – Uses thermal energy and pressure to create the connection
- WavelinQ System – Uses two magnetic catheters to create a channel between the vessels
The entire process usually takes less than an hour, and patients can go home the same day.
Why Choose a Percutaneous Fistula?
This modern approach offers many benefits over traditional surgical fistulas:
- Minimally invasive (no large incision)
- Faster recovery time
- Reduced risk of infection
- Improved cosmetic results (smaller scar or none at all)
- Comparable or better long-term function
Is It Right for Everyone?
Not every patient is a candidate for a percutaneous AV fistula. Your anatomy, vein size, and overall health must be evaluated. At FKMD, we perform detailed vascular imaging studies to determine if this option is right for you.
What Happens After the Procedure?
The fistula takes a few weeks to mature—this means the vein becomes stronger and larger so it can handle repeated dialysis sessions. During this time, you’ll be monitored closely. You may also receive physical therapy exercises to help the vein develop properly.
Why FKMD for Your Dialysis Access?
At FKMD, we specialize in minimally invasive, image-guided vascular procedures. Our team has extensive experience with both traditional and percutaneous AV fistulas. We’ll evaluate your case thoroughly and work with your nephrologist to provide a dialysis access plan tailored to your needs.
Take the First Step
Learning you need dialysis can be overwhelming, but you have options. If you’re interested in a less invasive approach with faster recovery, ask your doctor about a percutaneous AV fistula—or contact FKMD directly.
