Percutaneous AV Fistula for Dialysis Access
What is a Percutaneous AV Fistula?
A Percutaneous Arteriovenous (AV) Fistula is a minimally invasive, image-guided procedure that creates a connection between an artery and a vein—typically in the arm—to provide long-term, reliable access for dialysis. Unlike traditional surgical fistulas, this method is performed through a small puncture in the skin using catheters and ultrasound or X-ray guidance.
Percutaneous AV fistulas offer faster healing, less discomfort, and fewer complications compared to open surgery. They are a great option for patients with chronic kidney disease who need efficient and durable vascular access for hemodialysis.
How Does the Procedure Work?
During a percutaneous AV fistula procedure, Dr. Fabio Komlos uses ultrasound and X-ray guidance to access a vein and artery through a small puncture in the arm—no open surgery is required. A special device is then used to connect the artery and vein, allowing high blood flow necessary for dialysis.
The procedure typically takes less than an hour, is done under local anesthesia with light sedation, and most patients can go home the same day. Over the following weeks, the fistula naturally matures, becoming strong enough to handle regular dialysis sessions.
Who Can Benefit from a Percutaneous AV Fistula Procedure?
Patients with chronic kidney disease (CKD) or end-stage renal disease (ESRD) who need hemodialysis access can benefit from a percutaneous AV fistula. It’s especially ideal for those who may not tolerate open surgery well or want a less invasive option with faster recovery.
This procedure is also beneficial for patients with small or challenging vessels, or those who have had complications with previous surgical fistulas or grafts. With minimal discomfort and quicker healing, percutaneous AV fistulas provide a durable and reliable dialysis access for eligible patients.
What to Expect
Before the Procedure – Dr. Fabio Komlos will review your medical history, perform imaging (usually an ultrasound), and determine if you’re a good candidate for a percutaneous AV fistula.
During the Procedure – A small catheter is inserted into a vein and artery in your arm. Using real-time imaging, Dr. Komlos creates a connection between the two vessels. The procedure is minimally invasive, typically takes less than an hour, and is done under local anesthesia with mild sedation.
After the Procedure – Most patients go home the same day. You may feel mild soreness, but recovery is quick, and there are no large incisions or stitches. The fistula will begin to mature over the next few weeks until it’s ready for dialysis.
Follow-Up – Dr. Komlos will monitor your fistula with imaging to ensure it’s functioning properly and provide guidance on how to care for it at home.
"With percutaneous AV fistulas, we offer patients a safer, less invasive way to prepare for dialysis—without the need for surgery."

How long does a percutaneous AV fistula take to mature?
Most fistulas are ready for dialysis within 6 to 8 weeks, but this can vary depending on the patient’s vessel quality and overall health.
Am I a candidate for a percutaneous AV fistula?
If you have chronic kidney disease or end-stage renal failure and need hemodialysis, your doctor can evaluate your veins to see if you're a good candidate.
Is the procedure painful?
No. It’s done with local anesthesia and light sedation, so you’ll feel minimal discomfort during and after the procedure.
How long does the procedure take?
The procedure usually takes 30 to 60 minutes and most patients go home the same day.
How do I care for my new fistula?
Keep the site clean and dry, avoid heavy lifting with that arm, and follow your provider’s instructions for regular monitoring.
Can a percutaneous AV fistula be redone if it fails?
Yes. If a fistula fails or doesn’t mature properly, other options are available, including surgical creation or a different access site.
