Preparing for treatment
Before haemodialysis can start, you'll usually need to have a blood vessel called an arteriovenous fistula (AV fistula) created in your arm. This blood vessel is created by connecting an artery to a vein.

Joining a vein and an artery together makes the blood vessel larger and stronger. This makes it easier to transfer your blood into the dialysis machine and back again.

The operation to create the AV fistula is usually carried out around 4 to 8 weeks before haemodialysis begins. This allows the tissue and skin surrounding the fistula to heal.

If your blood vessels are too narrow to create an AV fistula, an alternative procedure known as an AV graft may be recommended. A piece of synthetic tubing is used to connect the artery to the vein.

As a short-term measure, or in an emergency, you may be given a neck line. This is where a small tube is inserted into a vein in your neck.
