Arteriovenous Fistula Creation
What is Arteriovenous Fistula Creation?
An arteriovenous fistula (AV fistula) creation is a surgical procedure that connects an artery to a vein, typically in the arm. This procedure is most commonly done for people who need hemodialysis due to kidney failure. An AV fistula provides a durable and accessible site for the repeated needle insertions required for dialysis. The increased blood flow from the artery into the vein causes the vein to grow larger and stronger, making it easier for healthcare providers to insert dialysis needles.
How to diagnose Arteriovenous Fistula Creation? When to consult a doctor?
Diagnosing the need for an AV fistula involves a comprehensive evaluation by healthcare professionals to determine if a patient requires hemodialysis and to assess the most appropriate type of vascular access.
You should consult a doctor if:
- Chronic Kidney Disease (CKD) or End-Stage Renal Disease (ESRD)
- Scheduled for Hemodialysis
- Signs of Vascular Access Issues
- Vascular Health Concerns
- Elective Dialysis Planning

Frequently Asked Questions
Keep the fistula clean, avoid putting pressure on the arm, check for the “thrill” (vibration over the fistula), and report any changes like swelling, redness, or absence of the thrill to your healthcare provider.
It typically takes 6 to 12 weeks for an AV fistula to fully mature and be ready for use in dialysis, but in some cases, it may take longer.
Risks include infection, bleeding, clotting, swelling, and in rare cases, the fistula may fail to develop properly or mature.
