An arteriovenous fistula (AV) in the left forearm is used to administer hemodialysis to an elderly patient with chronic kidney disease (CKD). When the AV fistula is being palpated, enlarged veins are a sign that it is working well.
In an AV fistula, the mixing of arterial and venous blood promotes the veins to expand (A), making cancellation for hemodialysis easier. Patients are connected to a dialysis machine via an AV fistula. Your dialysis procedure begins with the insertion of two needles by a nurse into the AV fistula. Blood is drawn using a single needle and sent to a machine where it is filtered. The blood can be safely injected back into the body using the second needle.
