What are aneurysms often caused by in dialysis patients?

Aneurysms in dialysis patients are often caused by insufficient healing time at insertion sites. When patients receive hemodialysis, access is typically created through arteriovenous (AV) fistulas or grafts. If the insertion sites for needles are not given adequate time to heal between treatments, the repeated trauma and disruption can compromise the integrity of the blood vessels, leading to weakened areas that may subsequently bulge or form aneurysms. Proper care and management of access sites are crucial to allow for sufficient healing, thereby reducing the risk of complications such as aneurysms.

Other factors, such as high blood flow rates or excessive needle gauges, may contribute to access-related complications, but insufficient healing time directly correlates to the physical stress placed on the vessel due to repeated needle punctures without allowing adequate recovery. Properly assessing and managing the healing process is essential in preventing these adverse outcomes.
