What could cause the formation of aneurysms and pseudoaneurysms?

The formation of aneurysms and pseudoaneurysms is closely linked to vascular access practices in hemodialysis. Poor rotation of sites can lead to a concentration of needle insertions in one area, resulting in repeated trauma to the blood vessels. This repeated trauma can weaken the vascular wall, eventually leading to the formation of an aneurysm, where the vessel dilates, or a pseudoaneurysm, which is a false aneurysm formed by the injury to the vessel.

Proper site rotation is crucial for maintaining the health of the blood vessels used for dialysis. When needles are repeatedly placed in the same area, they can cause inflammation and vascular damage, heightening the risk of complications such as aneurysms. Therefore, consistent rotation of dialysis access sites is essential to minimize these risks and maintain the integrity of the vascular access.
