What complication can arise from not rotating needle sites in grafts?

Thrombosis
Pseudoaneurysm
Infection
Hematoma

The correct answer is: Pseudoaneurysm

Not rotating needle sites in grafts can lead to the formation of a pseudoaneurysm. A pseudoaneurysm occurs when there is a disruption in the vessel wall, leading to a bulging of the vessel due to the pressure of blood within the tissue layers. Consistent needle placement at the same site can cause trauma to the vessel wall, increasing the risk of this condition. When needles are repeatedly placed in the same area, it can create localized stresses and weaken the arterial wall, potentially resulting in a pseudoaneurysm that compromises the integrity of the vascular access and can lead to further complications, such as rupture or infection. Proper rotation of needle sites helps distribute the stress on the vessel, reducing the chances of this significant complication arising.
