What is a common cause of pseufoaneurysm?

Pseudaneurysm is often associated with complications arising from the access sites used for dialysis, particularly when needles are repeatedly placed in the same location without sufficient rotation. If the same entry point is used continuously, it can lead to trauma and damage to the blood vessel wall, potentially resulting in the formation of a pseudaneurysm. This occurs because the repeated puncturing can weaken the vessel and cause blood to leak out, accumulating outside the vessel wall while still being contained by the surrounding tissue.

Rotating needle sites helps distribute the stress and trauma across a wider area, minimizing the risk of vessel damage and subsequent complications such as pseudaneurysm. Therefore, proper site rotation is a critical best practice in dialysis care to prevent this and other access-related complications.
