Why is a fistula considered the access of choice for dialysis?

A fistula is considered the access of choice for dialysis primarily because it has the lowest complication rate compared to other access types, such as catheters or grafts. This is critical for patients who require long-term dialysis, as maintaining a reliable access point significantly reduces the risk of infection and thrombosis, common complications associated with other access methods. A fistula, which is created by surgically connecting an artery and vein, typically results in improved blood flow and durability, making it possible to use it over an extended period without complications.

Additionally, because of the lower complication rates, patients with a fistula may experience fewer hospitalizations and need for invasive procedures to address issues like clotting or infection, leading to an overall better quality of life. This makes the fistula not only a preferable choice from a medical perspective but also from the standpoint of patient comfort and safety during dialysis treatments.
