Creation of AV Fistula or Graft for Dialysis
An arteriovenous (AV) fistula or graft is a vital lifeline for patients requiring hemodialysis. At The Cardiac & Vascular Institute (TCAVI), we specialize in creating durable and efficient vascular access to ensure safe and effective dialysis treatments.
How Does an AV Fistula or Graft Work?
AV fistulas and grafts are surgical connections made between an artery and a vein to facilitate hemodialysis. They serve as long-term access points, enabling the efficient flow of blood during dialysis sessions.
Types of Vascular Access
Types of Vascular Access
- AV Fistula: A fistula involves directly connecting an artery to a vein, typically in the arm. This allows the vein to grow stronger and larger over time, making it suitable for repeated needle insertions during dialysis.
- AV Graft: A graft uses a synthetic tube to connect an artery and vein, creating a looped pathway for blood flow. Grafts are ideal for patients whose veins are not suitable for a fistula.
Both options are designed to provide reliable access for dialysis while minimizing complications like clotting or infection.
Risks & Benefits of AAA Stent Repair
Benefits
- Improved Dialysis Efficiency: Both fistulas and grafts allow for higher blood flow rates, leading to more effective dialysis.
- Durability: AV fistulas, in particular, offer a long-term solution that can last years with proper care.
- Enhanced Quality of Life: Reliable vascular access reduces disruptions to dialysis schedules and improves overall health management.
Risks
- Infection: There is a potential risk of infection at the surgical site or within the vascular access.
- Clotting: Grafts are more prone to clotting than fistulas, which may require additional interventions.
- Delayed Use: AV fistulas require several weeks to months to mature before they can be used for dialysis.
- Access Failure: Both fistulas and grafts can occasionally fail, necessitating revision or alternative access creation.
Our team at TCAVI prioritizes minimizing these risks with meticulous surgical techniques and personalized aftercare.
What to Expect for the Procedure
Before the Surgery
A thorough evaluation will determine the most suitable type of access for your condition. Preoperative imaging helps map your blood vessels, ensuring optimal placement of the fistula or graft. You will also receive detailed instructions to prepare for the procedure.
During the Procedure
The procedure is typically performed under local anesthesia to ensure your comfort. For an AV fistula, the surgeon carefully connects an artery to a vein to allow blood to flow directly between them. In cases where a graft is needed, a biocompatible synthetic tube is placed to bridge the artery and vein. Advanced imaging tools are used throughout to ensure precision and proper positioning. The surgery generally takes 1-2 hours, depending on the complexity.
After the Procedure

After the Procedure
- You may experience mild soreness or swelling at the surgical site, which typically resolves within a few days.
- Regular follow-up visits are crucial to monitor the access site for proper function and early signs of complications.
- For fistulas, you will be guided on exercises to promote vein maturation, ensuring it is ready for use during dialysis.
Am I a Candidate for AV Fistula and Graft Creation?
AV fistula or graft creation is essential for individuals who:
- Are preparing to start hemodialysis for end-stage renal disease.
- Require a reliable and durable vascular access point.
- Have been evaluated and found suitable for surgical access by their care team.
