How is an AV fistula created?

The first step in AV fistula creation is to evaluate your blood vessels (veins and arteries), to ensure they are healthy enough to support a fistula. The first step in the evaluation will be a physical examination of your arms performed by your vascular specialist. The next step will involve the use of non-invasive or minimally invasive tests such as ultrasound, and possibly an angiogram to determine the size and depth of your arteries and veins. These tests will determine whether or not your blood vessels are able to support an AV fistula. These tests are often referred to as “vessel mapping.” Once it has been determined that you are a candidate for an AV fistula, an appointment will be scheduled for the AV fistula creation.

What is an AV fistula?

An AV fistula is a surgical connection made between an artery and a vein, created by a vascular specialist. An AV fistula is typically located in your arm, however, if necessary it can be placed in the leg. With an AV fistula, blood flows from the artery directly into the vein, increasing the blood pressure and amount of blood flow through the vein. The increased flow and pressure causes the veins to enlarge. The enlarged veins will be capable of delivering the amount of blood flow necessary to provide an adequate hemodialysis treatment. AV fistulas are the preferred vascular access for long-term dialysis because they last longer than any other dialysis access types, are less prone to infection and clotting, and can be relied upon for predictable performance.

What is Azura Vascular Care?

The interventional specialists and vascular surgeons at Azura are highly skilled in dialysis access creation and management. We can perform the AV fistula creation in our centers and help you manage your fistula when needed while you are on dialysis. At Azura Vascular Care, we work every day to deliver far more than our patients expect by bringing our full range of medical capabilities and service excellence to every patient, every visit at each of our centers nationwide.

Why do you need AV fistulas?

AV fistulas are the preferred vascular access for long-term dialysis because they last longer than any other dialysis access types, are less prone to infection and clotting, and can be relied upon for predictable performance.

How does an AV fistula affect blood flow?

With an AV fistula, blood flows from the artery directly into the vein, increasing the blood pressure and amount of blood flow through the vein. The increased flow and pressure causes the veins to enlarge. The enlarged veins will be capable of delivering the amount of blood flow necessary to provide an adequate hemodialysis treatment.

How long does it take for an AV fistula to mature?

After the AV fistula has been created, it will take several weeks, in some cases a month or longer, for the fistula to mature to the point where it will be able to be used for your hemodialysis treatments.

What are the advantages of an AV fistula?

Advantages of an AV fistula. Remains functional longer than other forms of vascular access. No synthetic material implanted in your body. Provides the necessary blood flow needed for effective dialysis, which may help to decrease treatment time. Low risk of infection.

How long after dialysis can you use a fistula?

a. "The fistula can be used 5 to 7 days after the surgery for dialysis treatment."

How long is cholecystitis surgery?

A client is admitted to the unit with acute cholecystitis. The health care provider has stated that surgery will be scheduled in 4 days. The client asks why the surgery is being put off for a week when he has a "sick gallbladder." What rationale would underlie the nurse's response?

What is a HeRO graft?

HeRO (Hemodialysis Reliable Outflow) Graft is a fully subcutaneous solution used to salvage a failing fistula or AV graft by bypassing central venous stenosis.

How long does a HeRO graft last?

The patients’ HeRO Grafts have continued to function at time of publication for fourteen (14) months (AVG salvage patient) and five (5) months (AVF salvage patient).

Can a HeRO graft be removed?

Removable & Replaceable: unlike a stent, HeRO Graft’s Venous Outflow Component can be removed & replaced if necessary

Does HeRO bypass require a bridging catheter?

The HeRO Graft implants avoided the need for use of bridging catheters.

Can AVF be used after HeRO?

Arm swelling resolved and AVF could be used immediately after being connected to HeRO Graft.

What is endoAVF procedure?

The endoAVF procedure is a minimally invasive way of creating a hemodialysis fistula. Under twilight sedation, the artery and vein in the arm are accessed with a small needle and tube through which the device is introduced. Tiny magnets on the device align, bringing the target artery and vein together. An energy pulse lasting less than one second creates a channel between the artery and vein, known as a fistula. The device and small tubes in the blood vessels are then removed.

Is endoavf a replacement for open surgery?

Therefore, this procedure is not a replacement for but instead a complement to open surgical fistula creation. By adding endoAVF creation to a patient’s options, we are increasing the number of potential dialysis access creation sites and helping patients with kidney failure live longer lives.

Do fistulas work in kidney failure?

A number of fistulas, endovascular or open surgical, will either never work or stop working over the course of time and additional access sites will need to be created.
