To begin, we need
to understand what AV fistulas and AV grafts are. The two are similar in that they create a new
pathway for blood flow between an artery and a vein and are often performed
when a patient has end-stage renal disease (ESRD) and is in need of dialysis. When an AV fistula is created a direct
anastomosis occurs between the artery and vein as illustrated in the picture
below.

This is different than the creation of an AV
graft which requires the use of some type of conduit, such as autologous or
synthetic material, to make the connection between the artery and vein as shown
below.
