Dialysis access refers to a surgical procedure that creates a pathway for blood to flow from the body to a dialysis machine and back. This access point serves as a connection that allows the artificial kidney machine to filter waste products and excess fluid from the blood. For patients with kidney failure, dialysis access represents a lifeline that makes regular dialysis treatments possible. Understanding the different types of access and what the procedure involves helps patients prepare for this step in their kidney care journey.

What Is Dialysis Access?

Dialysis access creates a connection point where needles can be inserted to remove blood for filtering and return clean blood to the body. Two types of dialysis access include a fistula and a graft. Each type serves the same basic function but differs in construction and longevity.

A fistula connects an artery directly to a vein. This connection allows the vein to enlarge and strengthen over time, creating a robust access point for dialysis needles. A graft uses a synthetic tube to connect an artery to a vein when a direct connection is not possible. The graft provides an alternative when blood vessels are too small or damaged for fistula creation.

Why Is It Performed?

Dialysis access becomes necessary when kidney function declines to the point where dialysis treatments are required. Chronic kidney disease progresses through five stages, with stage 5 requiring either dialysis or a kidney transplant. At this stage, the kidneys can no longer remove waste products and excess fluid effectively.

Early planning allows time for the access to mature and become ready for use before dialysis becomes urgent. This proactive approach prevents the need for emergency procedures or temporary access methods. The procedure also becomes necessary when existing access sites fail or develop complications. In these cases, new access must be created to continue dialysis treatments without interruption.

What Are the Benefits?

Properly functioning dialysis access provides reliable, long-term access to the bloodstream for dialysis treatments. A mature fistula can last for many years with proper care, reducing the need for additional surgical procedures. This longevity makes fistulas an effective access type for patients requiring long-term dialysis.

The access allows for adequate blood flow rates during dialysis, making treatments more efficient. Higher blood flow rates mean better clearance of waste products and toxins from the blood. This improved efficiency can lead to better overall health outcomes for patients undergoing dialysis.

Permanent access types, such as fistulas and grafts, may reduce the risk of infection compared to temporary catheters. The skin barrier remains intact except during needle insertion, providing natural protection against bacteria. Consulting a specialist helps determine if this procedure is suitable for your situation.

Consult a Vascular Surgeon

Dialysis access creation requires specialized surgical expertise to achieve the desired outcomes. A qualified vascular surgeon can evaluate your blood vessels and recommend the most appropriate type of access for your specific situation. Early consultation allows for proper planning and timing of the procedure.

Success depends on several factors, including the quality of the blood vessels, overall health status, and the timing of the procedure. Working with an experienced surgical team maximizes the chances of creating durable, well-functioning access. Schedule a consultation with a vascular surgeon to discuss your options and develop a comprehensive treatment plan.
