What is a fistula in the context of hemodialysis?

A fistula, within the context of hemodialysis, refers to a surgically created connection between an artery and a vein. This procedure is essential for patients requiring regular hemodialysis, as it provides a reliable access point to the bloodstream. The fistula allows for high blood flow rates necessary during dialysis treatments, facilitating the removal of waste products and excess fluids from the blood.

This access point is preferred over other methods, such as implanted catheters, because it generally results in better outcomes. Patients with a fistula experience fewer complications, such as infections or blood clots, and the fistula typically matures over time, improving its functionality. Understanding this surgical connection is critical for those involved in the care of patients undergoing dialysis, as it highlights the importance of preparing suitable access points that support effective treatment.
