Understanding the Breakdown of Surgically Created Arteriovenous Fistula
An arteriovenous fistula (AVF) is a surgical connection created between an artery and vein in the body to facilitate hemodialysis treatment for patients with kidney failure. The AVF is the preferred type of access for hemodialysis because it has fewer complications and longer lifespan than other types of access.
However, even with proper care and maintenance, an AVF can break down over time. Here are some common reasons why an AVF may break down:
- Stenosis: This is the most common cause of AVF breakdown. Stenosis is a narrowing of the blood vessels that can occur in the artery or vein that makes up the fistula. Stenosis can be caused by the buildup of scar tissue or the formation of blood clots, which can reduce blood flow.
- Thrombosis: Blood clots can form in the fistula, blocking blood flow and causing the fistula to fail.
- Aneurysm: An aneurysm is a bulge in the blood vessel wall. If an aneurysm develops in the fistula, it can disrupt blood flow and lead to fistula failure.
- Infection: Infection can occur in the fistula, leading to inflammation and scarring that can cause the fistula to fail.
- Steal syndrome: This is a rare complication of AVF. Steal syndrome occurs when blood flow is diverted from the hand to the fistula, causing the hand to become cold, numb, and painful.
If you experience any of the following symptoms, it is critical to contact your doctor immediately:
- Swelling or redness at the fistula site
- Pain or tenderness in the fistula arm
- Decreased or absent pulse in the fistula arm
- Inability to use the fistula for dialysis
If your AVF breaks down, your doctor may recommend a procedure to repair or replace the fistula. The type of procedure will depend on the cause and extent of the fistula breakdown. In some cases, a new fistula may need to be created in a different location.
To prevent AVF breakdown, it is essential to follow your doctor's instructions for care and maintenance. This may include keeping the fistula site clean, avoiding tight clothing or jewelry that can compress the fistula, and avoiding activities that can damage the fistula, such as heavy lifting or repetitive motions.
By understanding the causes and symptoms of AVF breakdown and taking steps to prevent it, you can
