A-V graft: The surgical joining of an artery and a vein with an artificial piece of material.
A-V fistula: The surgical joining of an artery and a vein directly together without an artificial piece of material.
Bruit (pronounced brew-e): The swishing sound over the fistula/graft heard through a stethoscope.
Dialysate: A solution used in the process of dialysis to aid in the removal of excess fluid and waste by way of the artificial kidney.

Edema: Swelling from excess fluid, usually seen in the ankles or lower leg areas, fingers, around eyes and, most seriously, in the lungs where it can cause shortness of breath.
Epogen™ (EPO): A synthetic hormone used as a replacement therapy to increase the number of red blood cells that the body manufactures.

Thrill: A buzzing type feeling that can be felt over the fistula/graft.
Vascular access: The surgical joining of an artery and a vein under the skin either directly (A-V fistula) or with an artificial piece of material (A-V graft) for the purpose of hemodialysis.
Vein: A blood vessel in the body that carries blood back to the heart.
