🩸 AV Fistula (Arteriovenous Fistula)

An AV Fistula is a surgical connection made between an artery and a vein, usually in the arm, to provide vascular access for hemodialysis. It is considered the best and most durable option for patients with chronic kidney failure who need long-term dialysis.

⚙️ How is it created?

• A vascular surgeon performs a minor surgery to connect an artery to a nearby vein.

• This connection causes the vein to become larger and stronger, making it suitable for repeated needle insertions during dialysis.

• Common sites: forearm (radiocephalic fistula) or upper arm (brachiocephalic fistula).

⏱️ Maturation Time:

• The fistula takes about 4 to 8 weeks (or longer) to mature and become usable for dialysis.

• During this time, the vein enlarges and the blood flow increases.

✅ Advantages of AV Fistula:

• Longest lifespan among dialysis access types

• Lower risk of infection

• Better blood flow, which leads to more effective dialysis

• Fewer complications compared to catheters or grafts
