What is an AV Fistula for Hemodialysis?

In order for a dialysis machine to clean excess fluid or waste material from a person's blood, the patient needs to be connected to the machine, usually for several hours, three times a week. This connection, or fistula, is often made in the patient's arm, where an artery is surgically connected to a vein.
