AV Fistula Creation
It is a surgical procedure performed to provide long-term and reliable vascular access in patients who will undergo hemodialysis treatment.
45 - 60 min
What Is an AV Fistula?
An AV fistula is an artificial vascular connection created by surgically joining an artery and a vein. Through this connection, the vein enlarges, its wall thickens, and it becomes suitable for dialysis needles.
Why Is an AV Fistula Preferred?
- Long-term usability
- Lowest risk of infection
- High blood flow capacity
- Fewer complications compared to catheters
- Higher dialysis efficiency
How Is an AV Fistula Created?
Before the procedure, vascular mapping is performed with Doppler ultrasonography to identify the most suitable vessels. An AV fistula is usually created in the arm (at the wrist or elbow level) under local anesthesia. The procedure typically takes about 45–60 minutes.

- Patients with chronic kidney failure who are planned to undergo hemodialysis
- Cases expected to require dialysis in the near future
- Patients with a high risk of complications related to catheter use
After the fistula is created, it is not used immediately. A maturation period of 4–8 weeks is required for the vein to become suitable for dialysis. During this period, the fistula is monitored regularly.
- Long-lasting vascular access
- Low risk of thrombosis and infection
- More stable blood flow during dialysis
- Improved quality of life for the patient
AV fistula creation is the first-line method that should be preferred in all hemodialysis patients whose general condition is suitable and whose vascular structure is appropriate.
