Vascular access thrombosis is a significant and common complication associated with long-term dialysis access, particularly in patients with arteriovenous (AV) fistulas or grafts. Over time, the access site can become narrowed or obstructed due to factors such as the formation of clots or stenosis, which can significantly impair blood flow. Thrombosis can lead to increased difficulty in performing dialysis and may necessitate surgical interventions to restore patency or the creation of new access sites.

In the context of long-term dialysis, monitoring and maintaining the integrity of the vascular access is critical to ensure effective treatment. Regular assessments and proactive measures, such as ensuring adequate blood flow rates and using appropriate medications like anticoagulants if indicated, are important in preventing thrombosis. Understanding this complication helps nurses and healthcare providers implement strategies aimed at reducing its occurrence, thus improving overall patient outcomes on dialysis.
