Arteriovenous fistula ultrasound is an ultrasound of the arm or leg where you have a fistula for dialysis.
Through a hand-held transducer and gel applied directly on your skin, ultrasound uses non-radiation sound wave technology to create an echo image of the organs and vessels in your body.
The purpose of the scan is to check the arteries and veins around the fistula site to check function and ensure patency.
Your arteriovenous fistula ultrasound results will be reviewed and the report will be sent to your referring doctor. It is best to make an appointment with them to follow up on the results.
A fistula is created surgically by a surgeon. It connects the artery to the vein. A fistula is a prominent direct connection between a vein and an artery, usually bypassing the capillary system.
AV fistulas can last for years, or they can fail in a few months. It depends on various factors, including the anatomy of your fistula, your underlying condition, and your level of activity.
Over time, your veins will thicken, and your fistula will become less visible. This can make it hard to tell if your fistula is failing. For this reason, your cardiologist may recommend an ultrasound every six months or so.

Who performs the arteriovenous fistula ultrasound?
The arteriovenous fistula ultrasound is performed by a qualified sonographer or vascular technologist. These professionals are trained to conduct the ultrasound and interpret the results to ensure proper monitoring of dialysis access.
What conditions can an AVF scan detect?
The conditions that an AVF scan can detect include stenosis, thrombosis, and other complications related to arteriovenous fistulas used for dialysis access. These assessments are crucial for ensuring optimal blood flow and dialysis efficiency.
Is there any pain during a fistula scan?
The experience of pain during a fistula scan is minimal. Most patients report only mild discomfort, similar to the sensation of a light pressure, making the procedure generally well-tolerated.
How do I book an AVF ultrasound appointment?
Booking an AVF ultrasound appointment is simple. You can schedule your appointment online through our website or by calling our office directly to speak with a representative who can assist you.
What should I wear for a fistula scan?
For a fistula scan, it is recommended to wear loose-fitting clothing that allows easy access to your arm where the fistula is located. Avoid tight sleeves or accessories that may obstruct the scan.
Can I bring someone to my AVF ultrasound?
You can bring someone to your AVF ultrasound. Having a companion can provide support and comfort during the procedure.
What is the follow-up after an arteriovenous fistula ultrasound?
The follow-up after an arteriovenous fistula ultrasound involves reviewing the results with your healthcare provider to assess the fistula's function and determine if any further action is necessary to ensure optimal dialysis access.
How does an AVF scan help in dialysis?
An AVF scan helps in dialysis by assessing the health and functionality of the arteriovenous fistula, ensuring optimal blood flow for effective dialysis treatment and early detection of any complications that may arise.
What imaging techniques are used in fistula ultrasounds?

Understanding Arteriovenous Fistulas
An arteriovenous fistula (AV fistula) is a surgically created connection between an artery and a vein, primarily used for patients requiring long-term dialysis. This connection allows for easier access to the bloodstream, facilitating the removal and return of blood during dialysis treatments.
AV fistulas are preferred over other access methods, such as grafts or catheters, due to their lower risk of infection and longer lifespan. Regular monitoring through ultrasounds is essential to ensure the fistula remains patent and functional, which is crucial for effective dialysis.
Preparation for Arteriovenous Fistula Ultrasound
Preparing for an arteriovenous fistula ultrasound is straightforward and typically requires minimal effort from the patient. It is recommended to wear loose-fitting clothing to allow easy access to the area being examined, usually the arm or leg where the fistula is located.
Patients should also inform their healthcare provider about any medications they are taking or any recent changes in their health status. This information can help the technician conduct the ultrasound more effectively and ensure accurate results.
What to Expect During the Ultrasound Procedure
During the arteriovenous fistula ultrasound, a technician will apply a gel to the skin over the fistula and use a handheld transducer to capture images. The procedure is painless and typically lasts about 30 minutes, during which the technician may ask the patient to adjust their position for optimal imaging.
Patients may hear sounds from the ultrasound machine, which are normal and indicate the flow of blood through the fistula. The technician will analyze the images to assess the fistula's condition, looking for any signs of narrowing or other complications.
Post-Ultrasound Care and Follow-Up
After the arteriovenous fistula ultrasound, patients can resume their normal activities immediately, as there are no side effects from the procedure. However, they should monitor the fistula site for any unusual changes, such as increased swelling or pain, and report these to their healthcare provider.
Follow-up appointments are typically scheduled every six months to monitor the fistula's health. These routine checks are vital for ensuring that the fistula remains functional for dialysis treatments and to catch any potential issues early.
