AV Fistula Creation

AV Fistula Creation is a surgical procedure that establishes a direct connection between an artery and a vein, typically in the arm, to provide access for hemodialysis in patients with end-stage renal disease (ESRD).

Purpose of AV Fistula Creation:

The main objective of AV fistula creation is to provide a reliable and durable access point for hemodialysis, a treatment required to filter the blood of patients whose kidneys are no longer functioning properly. Hemodialysis requires high blood flow, which can be achieved by connecting an artery to a vein, allowing the vein to enlarge and strengthen to support repeated needle insertions for dialysis.

Why a Cardiovascular and Thoracic Surgeon Might Perform the Procedure:

• Complex Vascular Anatomy: Some patients may have difficult vascular anatomy, such as smaller or damaged blood vessels, requiring the advanced skill set of a cardiovascular and thoracic surgeon.
• Pre-existing Cardiovascular Conditions: Patients with cardiovascular diseases (such as peripheral artery disease, or previous bypass surgeries) may require a CVTS to ensure proper blood flow through the fistula and minimize complications.
• Revisions or Redo Procedures: In some cases, patients with failed previous fistula creations or other vascular complications may require the expertise of a cardiovascular and thoracic surgeon to revise or re-create the fistula.

Advantages of AV Fistula:

• Durability: AV fistulas typically last longer than other forms of vascular access (e.g., synthetic grafts or central venous catheters).
• Low Risk of Infection: Since it uses the patient's own blood vessels, the risk of infection is significantly lower.
• Lower Risk of Clotting: The natural connection between the artery and vein reduces the likelihood of clot formation.
