Overview
An arteriovenous (AV) fistula connects an artery directly to a vein, usually in the forearm or upper arm. The increased blood flow makes the vein larger and stronger over several weeks, so it can be used for repeated dialysis needles.
Why it is done
- To prepare for long-term haemodialysis
- A fistula usually lasts longer and causes fewer infections than a dialysis catheter
Before the surgery
Your team may check the blood vessels in your arms with an ultrasound scan. Protect the veins in the chosen arm by avoiding blood tests and drips in that arm where possible.
During the surgery
The operation is usually done under local or regional anaesthesia and takes about one to two hours.
After the surgery
The fistula usually needs 6 to 12 weeks to mature before it can be used. You will be shown how to check for the buzzing feeling (thrill) that shows it is working, and how to protect the arm.
Risks
Possible risks include bleeding, infection, the fistula not maturing, clotting and, rarely, reduced blood flow to the hand.
