What is a pseufoaneurysm?

A pseudoaneurysm is characterized as a bubble-like blister that forms in the graft due to a weakness in the graft wall. This occurs when there is a disruption in the vascular structure, leading to the collection of blood outside of the vessel wall but still within the surrounding tissues.

In the context of hemodialysis, pseudoaneurysms can develop around the site where the graft is created for dialysis access, typically as a result of repeated needling. The formation of a pseudoaneurysm is significant as it may lead to complications such as thrombosis or rupture, which can pose serious risks to the patient.

Understanding the formation and significance of pseudoaneurysms is crucial for healthcare providers in the dialysis setting, as this knowledge aids in monitoring vascular access sites and ensuring patient safety. The other options refer to different complications related to dialysis but do not define what a pseudoaneurysm is.
