When the kidney's functioning is hampered, they can no longer filter or remove the toxins from the blood effectively. Thus, dialysis treatment is required, which involves taking out the blood for filtering and returning the clean blood to the body. The most common form of dialysis is hemodialysis, which requires a vascular access point to take the blood out and return it back. For dialysis, two access points are created. The first one is connected to an artery from where blood flows through a tube to the dialyzer for filtration. Then the clean blood flows back to the body through another tube which is connected to a vein. Once the AV fistula is created, the vein will become thicker and wider over time, thus, allowing better blood flow during dialysis treatment. Generally, veins are smaller than arteries and have low pressure. Naturally, veins cannot handle high-pressure blood. Thus, an artery is adjoined with the vein to enlarge it over time so that it can handle the high-pressure blood entering the body during dialysis. This allows a safe hemodialysis treatment.
Before undergoing an arteriovenous (AV) fistula, several diagnostic tests and evaluations are typically performed by the vascular surgeon to assess the suitability of the patient's blood vessels and overall health.
Here are some of the diagnostic tests performed prior to the AV Fistula treatment:
The diagnostic tests and evaluations conducted may vary depending on the individual patient's health condition and the healthcare provider's preferences. The purpose of these assessments is to ensure that the patient is a suitable candidate for AV fistula surgery and to optimize the chances of a successful outcome.
There are different types of arteriovenous (AV) fistulas that can be created for dialysis access. The choice of AV fistula type depends on various factors, including the patient's vascular anatomy and overall health, here are the different types of AV fistulas:
It is important to note that the choice of AV fistula type depends on individual patient factors, such as the condition of blood vessels, vessel size, quality, and suitability for surgery. The healthcare provider will evaluate the patient's vascular anatomy and determine the most appropriate type of AV fistula for optimal dialysis access.
Preparation for arteriovenous (AV) fistula surgery involves several steps to ensure the best possible outcome and minimize the risk of complications.
Here are some common preparation steps for AV fistula surgery:
The AV fistula procedure is a surgical intervention that involves creating a connection between an artery and a nearby vein to provide access to hemodialysis.
Here is an overview of the AV fistula procedure:
An arteriovenous (AV) fistula is considered the preferred access for hemodialysis because it offers several benefits over other forms of vascular access. Here are some of the benefits of AV fistula for dialysis:
Not all patients may be suitable candidates for AV fistula creation due to various factors such as the condition of their blood vessels or overall health. The decision to proceed with an AV fistula should be made in consultation with a healthcare provider who can assess individual circumstances and determine the most appropriate access option for dialysis.
After AV fistula surgery, there are several things you can expect during the recovery process; here are some common aspects:
It is quite important to follow your healthcare provider's instructions, take any prescribed medications, and attend all follow-up appointments to ensure a smooth recovery and optimize the long-term success of the AV fistula. If you have any concerns or experience unusual symptoms during the recovery period, it is important to contact your healthcare provider promptly.
While AV fistula surgery is generally considered safe and effective, there are some possiblerisks and complications that can arise. It is important to be aware of these possibilities before undergoing the procedure.
Here are some potential risks and complications associated with AV fistula surgery:
The recovery process after AV fistula surgery for dialysis can vary depending on the individual patient and the extent of the surgery. Generally, the surgical site heals within 10-14 days, and the fistula takes around 6 to 8 weeks approximately. The fistula will be ready for hemodialysis only when the vein enlarges enough to support dialysis treatment. During the recovery period, the patient is advised to make certain lifestyle adjustments and restrict physical activities that can put undue pressure on the surgical site.
Follow the instructions and recommendations given by the doctor and dialysis team regarding the care and use of the AV fistula.
By following these care tips, patients can prolong the lifespan of the arteriovenous fistula and get safer hemodialysis treatment with minimal complications.

On average, the cost of AV fistula surgery in India can range from Rs. 80,000 to Rs. 1,50,000. This cost generally covers the surgical procedure, location of the treatment, surgeon's fees, anesthesia, hospital stay, and basic postoperative care.
Yes, an AV fistula can be repaired if it gets damaged. The repair may involve surgical or non-surgical techniques, depending on the extent of the damage. If the fistula fails entirely, another vascular access will be created.
The lifespan of an AV fistula can vary depending on the individual patient and how well it is cared for, but it typically lasts for several years. However, if the patient is diabetic or suffers from vascular disease, the longevity of the arteriovenous fistula is reduced significantly.
Yes, AV fistula is a completely safe process, whereas just like other surgical interventions there are some minor risks such as chances of infection, bleeding, and discomfort due to anesthesia.
The AV fistula treatment is covered under insurance, however, this insurance coverage depends on the health insurance plan of the patient. It is always recommended to consult with the insurance provider regarding the policy details before undergoing the AV fistula treatment.
