About AV Fistula (AVF) for Dialysis
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.
Diagnostic Tests & Evaluations Done Before AV Fistula
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:
- Physical Examination: A complete physical examination is conducted to assess the patient's overall health, evaluate the condition of the blood vessels, and identify any potential issues that may affect the AV fistula surgery.
- Blood Tests: Blood tests are performed to evaluate the patient's blood cell counts, kidney function, clotting factors, and overall health. This helps determine if the patient is at increased risk of complications during or after the surgery.
- Duplex ultrasound: Duplex ultrasound is the most effective and common way to check for an arteriovenous fistula in the legs or arms, this process involves the use of sound waves to evaluate the speed of blood flow.
- Computerized tomography (CT) angiogram: CT angiogram is an imaging test that can show if blood flow is bypassing the capillaries. The IV contrast dye helps blood vessels show up more clearly in the images.
- Magnetic resonance angiography (MRA): The MRA test is performed if the patient observes some signs of an arteriovenous fistula deep under the skin. Like an MRI, a magnetic resonance angiography (MRA) uses a magnetic field and radio waves to create pictures of the body's soft tissues.
- Cardiovascular Evaluation: Patients are suggested to undergo a cardiovascular evaluation, which may include an electrocardiogram (ECG) to assess heart function and stress tests to evaluate cardiovascular fitness.
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.
Types of AV Fistula
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:
- Radiocephalic Fistula: Radiocephalic fistula is the most common and preferred type of AV fistula. It involves connecting the radial artery in the forearm to a nearby cephalic vein. The radiocephalic fistula is often favored due to its high success rate, good blood flow, and lower risk of complications. It is generally the first and foremost choice when the patient's blood vessels are suitable.
- Brachiocephalic Fistula: A brachiocephalic fistula involves connecting the brachial artery in the upper arm to the cephalic vein in the upper arm or shoulder area. It is an alternative option when the radial artery is unsuitable or unavailable for a radiocephalic fistula. The brachiocephalic fistula provides good blood flow rates and is considered a reliable and durable option.
- Brescia-Cimino Fistula: The Brescia-Cimino fistula is a type of AV fistula that involves connecting an artery in the upper arm (usually the radial artery) to a nearby vein, typically the cephalic vein. It can be either a side-to-side or an end-to-side connection. The Brescia-Cimino fistula is similar to the radiocephalic fistula but may involve a different vein or anastomotic technique.
- Upper Arm Loop/Graft Fistula: In cases where the patient's blood vessels are not suitable for a direct AV fistula, an AV graft may be used. An AV graft involves placing a synthetic tube (graft) between an artery and vein to create the connection for dialysis. The graft is typically placed in the upper arm, forming a loop configuration. Grafts are generally used when the patient's blood vessels are small, weak, or unsuitable for a fistula.
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 AV Fistula Surgery
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:
- Medical Evaluation: Before the surgical process, you will undergo a thorough medical evaluation. This may include a review of your medical history, physical examination, and various tests, such as blood tests, imaging studies (ultrasound or angiography), and vascular mapping. These assessments help determine the suitability of your blood vessels for AV fistula creation and identify any underlying health conditions that need to be managed.
- Medication Review: The vascular surgeon will review your current medications and may make adjustments as necessary. Some medications, such as blood thinners or antiplatelet drugs, may need to be temporarily stopped or adjusted before surgery to reduce the risk of bleeding during the procedure. It is important to follow your healthcare provider's instructions regarding medication management.
- Informed Consent: It is suggested to be familiar with the detailed information about AV fistula surgery, including the risks, benefits, and alternatives. You will have an opportunity to ask questions and discuss any concerns with your healthcare provider. Once you have a clear understanding of the procedure, you will be asked to give informed consent for the surgery.
- Food intake: You will mostly be instructed to fast for a certain period of time before the surgery, usually from midnight the night before. Fasting helps minimize the risk of complications during the procedure, particularly those related to anesthesia.
- Preoperative Preparations: On the day of surgery, you may be asked to shower using an antiseptic soap to reduce the risk of infection. You will receive specific instructions regarding dressing with loose-fitting clothes, and when to arrive at the hospital or surgical center.
- Anesthesia: AV fistula surgery is usually performed under local anesthesia, which numbs the surgical area while allowing you to remain awake. In some rare cases, general anesthesia may be used, particularly if additional procedures or interventions are planned alongside the fistula creation. The type of anesthesia will be determined based on your specific case and the preference of the surgical team.
- Supportive Care: It is important to arrange for someone to accompany you to the hospital or surgical center on the day of surgery and provide support during the recovery period. They can assist with transportation, help with post-operative care, and offer emotional support.
What happens during the AV Fistula Procedure?
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:
- Anesthesia: The procedure is typically performed under local anesthesia, which numbs the surgical area while allowing the patient to remain awake. In some cases, general anesthesia may be used, particularly if additional procedures or interventions are planned alongside the fistula creation.
- Incision: The surgeon makes an incision over the selected area where the artery and vein are accessible. The most common locations for AV fistula creation are the forearm or the upper arm.
- Arterial and venous exposure: The surgeon carefully exposes the artery and vein in the surgical area. The specific artery and vein selected depend on the patient's vascular anatomy and the surgeon's preference.
- Anastomosis: The surgeon creates a connection or anastomosis between the artery and the vein. This is typically done by making a small opening in the artery and attaching it to the vein using sutures or clips. The connection allows arterial blood to flow directly into the vein.
- Blood flow evaluation: After creating the connection, the surgeon evaluates the blood flow through the fistula to ensure proper function. This may involve using Doppler ultrasound or other techniques to assess the flow rate and confirm that the fistula is functioning appropriately.
- Closure: Once the blood flow is confirmed to be satisfactory, the surgeon closes the incision with sutures or staples. Sterile dressings and bandages are applied to the surgical site.
- Post-operative Care: After the procedure, the patient is monitored in a recovery area to ensure stable vital signs and adequate pain control. The healthcare team provides instructions on wound care, limitations, and any necessary follow-up appointments. Following the AV fistula procedure, the newly created fistula requires time to mature and develop adequate blood flow. This maturation period typically takes several weeks to months. During this time, the vein enlarges and becomes stronger to accommodate the increased blood flow required for dialysis.
Benefits of AV Fistula Treatment
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:
- Longevity: AV fistulas have the capability to provide long-term access to dialysis. Compared to other types of access, such as catheters or grafts, AV fistulas have a lower risk of complications and tend to last longer. With proper care, an AV fistula can function for many years, reducing the need for frequent access placement procedures.
- Lower infection risk: AV fistulas have a lower risk of infection compared to other types of access. Infections can be a significant concern for individuals undergoing dialysis, as they can lead to serious complications. AV fistulas are created using the patient's own blood vessels, reducing the risk of infections associated with foreign materials or devices.
- Improved blood flow: AV fistulas are created by surgically connecting an artery to a vein. Over time, the increased blood flow through the vein causes it to enlarge and become stronger. This improved blood flow allows for efficient and effective dialysis treatments, as it provides adequate blood flow rates and facilitates the removal of waste products and excess fluid from the body.
- Lower risk of thrombosis: AV fistulas have a lower risk of blood clot formation (thrombosis) compared to synthetic grafts or catheters. The natural blood flow through the surgically created connection helps maintain the patency of the fistula. This reduces the need for interventions to address clotting issues and ensures uninterrupted dialysis treatments.
- Cost-effectiveness: AV fistulas are generally more cost-effective and affordable than other forms of vascular access, such as catheters or grafts. Once a fistula is established, it does not require the ongoing cost of catheter maintenance or the need for repeated access placement procedures. This can lead to cost savings over the long term.
- Better quality of dialysis: AV fistulas generally provide better dialysis outcomes in terms of clearance of waste products and fluid removal. The improved blood flow and adequate dialysis delivery achieved through an AV fistula contribute to more effective and efficient dialysis treatments.
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.
What to Expect After AV Fistula Surgery?
After AV fistula surgery, there are several things you can expect during the recovery process; here are some common aspects:
- Hospital stay: Following AV fistula surgery, you will typically stay in the hospital for a day or two for close monitoring. The length of the hospital stay may vary depending on the specific circumstances and the surgeon's preference.
- Pain and discomfort: Post-surgery, some patients might experience some pain, swelling, and discomfort around the surgical site. Your healthcare team will provide appropriate pain management to keep you comfortable during the recovery period.
- Bandages and Dressings: With the help of bandages, the surgical site is covered to protect and promote the healing process. These dressings may need to be changed regularly, and your healthcare team will provide instructions on caring for the incision site.
- Restrictions on Arm Use: To allow the AV fistula to heal properly, you may be advised to limit the use of the arm on the side of the surgery. This may involve avoiding heavy lifting, strenuous activities, or any activities that put excessive strain on the surgical site.
- Follow-up Appointments: You will need to attend regular follow-up appointments with your healthcare team to monitor the healing progress of the AV fistula. These appointments allow the healthcare provider to assess the function of the fistula and address any concerns or complications that may arise.
- Fistula Maturation: It is important to note that after the surgery, the AV fistula needs time to mature and become fully functional. This process typically takes several weeks to a few months. During this time, the vein enlarges, strengthens, and develops the necessary blood flow for dialysis or other medical procedures.
- Education and Care Instructions: Your healthcare team will provide you with instructions on how to care for your AV fistula, including proper cleaning, monitoring for signs of infection, and steps to prevent complications. They will also educate you on the signs and symptoms of potential problems, such as infection, clotting, or narrowing of the fistula.
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.
Potential Risks & Complications of AV Fistula Surgery
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:
- Infection: There is a risk of infection at the surgical site. Signs of infection may include redness, swelling, warmth, pain, or drainage from the incision. Infections should be promptly treated with antibiotics.
- Bleeding: Bleeding can occur during or after the surgery. In rare cases, it may require additional procedures or interventions to control the bleeding.
- Clotting: Blood clots (thrombosis) can form within the AV fistula, obstructing blood flow. This can lead to inadequate dialysis or poor circulation. Clotting may require intervention, such as medication or additional procedures to restore blood flow.
- Poor Maturation: Sometimes, the AV fistula fails to mature properly, meaning it does not develop adequate blood flow and strength. This can limit its effectiveness for dialysis or other medical procedures. In such cases, additional interventions may be necessary, such as angioplasty or surgical revision.
- Steal Syndrome: In rare cases, the AV fistula can cause a condition known as steal syndrome. This occurs when blood flow to the hand and fingers is compromised, leading to symptoms such as pain, numbness, or weakness. It usually arises due to excessive blood flow through the fistula, diverting blood away from the hand. Treatment may involve surgical or endovascular procedures to improve blood flow.
- Nerve Damage: During the surgery, there is a small risk of nerve damage that can lead to sensory or motor deficits in the hand or arm. This can result in numbness, weakness, or loss of function. Most cases of nerve damage are temporary, but in rare instances, permanent damage can occur.
- Abnormal Scarring: The surgical incision may heal with abnormal scarring, such as hypertrophic scars or keloids. These scars can be raised, thickened, or itchy. Various treatments, such as topical therapies or scar revision surgery, may be available to address abnormal scarring if necessary.
- Other General Surgical Risks: AV fistula surgery carries the general risks associated with any surgical procedure, such as adverse reactions to anesthesia, blood clots, respiratory problems, or cardiovascular complications.
Recovery Process after AV Fistula
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.
- Wash the incision site daily with soap and water, and avoid using creams, lotions, or oils on the incision site.
- Avoid wearing tight clothing or jewelry that can constrict the site of incision.
- Do not carry heavy objects or sleep on the side of the incision, as this can cause pressure on the fistula.
- Avoid needle sticks or blood pressure measurements on the access site.
- Avoid smoking or using tobacco products, as they can affect blood flow and increase the risk of complications.
- Keep the access site well-nourished and hydrated by eating a balanced diet and drinking plenty of fluids.
- Perform gentle exercises and movements of the arm on the side of the access site to promote blood flow and prevent clotting.
- Use a soft cushion or pillow to support the access site during dialysis treatments to prevent damage or discomfort.
- Attend regular appointments with the doctor to monitor the function of the AV fistula and detect any potential complications early.
- Look out for signs of infection, such as redness, swelling, tenderness, or discharge at the access site.
- Check the blood flow in your AV fistula regularly by placing your fingers over the access site. If you feel a buzzing sensation or hear a bruit (whooshing sound), it means the blood flow is good.
- Do not skip dialysis sessions or deviate from the treatment plan without consulting the doctor, as this can lead to complications and jeopardize the health.
By following these care tips, patients can prolong the lifespan of the arteriovenous fistula and get safer hemodialysis treatment with minimal complications.
