A prosthetic arteriovenous graft (AVG) represents a type of vascular access for haemodialysis (HD), employing a synthetic conduit that replaces a native vessel and permits repeated cannulation. Due to their associated complications, particularly thrombosis and infection, arteriovenous grafts (AVGs) have long been regarded as a secondary option. Current recommendations advocate an individualized approach to vascular access planning based on patient´s anatomy, life expectancy, anticipated dialysis duration, and personal preferences, leading to a broader and more flexible use of AVGs. Their key advantage is the potential for early initiation of HD, while minimizing the need for central venous catheters. However, a major disadvantage of AVGs is their tendency to develop stenotic lesions, predominantly at the venous anastomosis, which adversely affects graft patency. If left untreated, this may lead to graft thrombosis. Regular evaluation of AVG function is essential for early detection of stenosis and maintenance of graft patency. Despite its widespread use in clinical practice, the role of AVG surveillance in vascular access management remains a subject of considerable debate, as current evidence regarding its effectiveness in preventing thrombosis and prolonging graft patency is inconclusive.

Keywords: prosthetic arteriovenous grafts, haemodialysis, indications, surveillance
