What is Dialysis Vascular Access?

Dialysis vascular access is the connection between your bloodstream and the dialysis machine, allowing for the efficient removal of waste, excess fluids, and toxins when your kidneys can no longer perform these functions. There are three main types of vascular access:

  • Arteriovenous (AV) Fistula: A surgical connection between an artery and a vein, typically in the arm, allowing for strong and reliable blood flow.

  • Arteriovenous (AV) Graft: A synthetic tube placed under the skin to connect an artery and a vein when a fistula is not feasible.
  • Central Venous Catheter (CVC): A temporary access option used in urgent situations, typically placed in a large vein in the neck or chest.

Why is Vascular Access Important?

A well-functioning vascular access is essential for effective dialysis. Without proper access, dialysis treatment may not be sufficient, leading to complications. Early planning and maintenance of vascular access improve treatment outcomes and reduce the risk of infections and clotting.

How to Care for Your Vascular Access

  • Keep the access site clean and dry.
  • Avoid heavy lifting or pressure on the access arm.
  • Monitor for signs of infection, swelling, or decreased blood flow.
  • Follow your healthcare provider’s recommendations for routine check-ups and maintenance procedures.

Dialysis Vascular Access Procedures

Our goal is to ensure that patients receive uninterrupted, high-quality dialysis treatment by addressing access-related complications promptly and effectively. Carolina Access Center is committed to providing expert care in maintaining dialysis vascular access, enhancing patient well-being, and improving overall treatment success.

Dialysis Access Maintenance and Intervention

Carolina ASC specializes in the maintenance and care of existing dialysis vascular access, including AV fistulas, AV grafts, and central venous catheters. Over time, these access sites may develop complications such as blockages, narrowing (stenosis), or clotting, which can impact dialysis treatment. Our team performs minimally invasive procedures to restore and maintain proper function, including:

  • Angiogram and Angioplasty: Imaging and balloon expansion to open narrowed access sites and restore blood flow.
  • Thrombectomy: Removal of blood clots that may form in dialysis grafts or fistulas, preventing blockages.
  • Stent Placement: Insertion of a small mesh tube to keep vessels open and improve blood flow in cases of significant narrowing.
  • Catheter Exchange and Removal: Safe and efficient exchange or removal of dialysis catheters to prevent infection and ensure proper dialysis function.
  • Coil Embolization Procedures: A minimally invasive technique used to treat vascular malformations and excessive blood flow within dialysis access. Small coils are inserted into the blood vessels to block or redirect blood flow, improving dialysis efficiency and reducing complications.
