What is a common disadvantage associated with AV fistulas?

A common disadvantage associated with AV fistulas is the long length of time required for them to mature and be ready for use. After surgical creation, an AV fistula does not provide immediate access for dialysis. Typically, it takes several weeks to months for the fistula to develop adequate blood flow and become suitable for dialysis procedures. During this maturation period, the fistula undergoes changes that increase the diameter and strengthen the walls of the blood vessels, allowing for optimal function and minimizing complications during dialysis.

Understanding this aspect is crucial for patient care technicians, as it highlights the need for proper patient education regarding the timeline of AV fistula availability. This timing must be factored into patient treatment plans, especially when they require ongoing dialysis.
