Because veins tend to have weak blood flow, doctors often connect one of the patient’s nearby arteries to the vein being accessed for dialysis.

Why is the radial artery chosen for dialysis?

Conclusions: Radial artery-perforating vein fistulas have an acceptable survival rate and do not produce circulatory complications. This method may be applicable for AVF creation in patients with forearm vein destruction/abnormalities and as a rescue procedure for an old clotted fistula after kidney transplant failure.

Why is artery used in dialysis?
