title: Vascular Access Monitoring and Surveillance: An Update.
abstract: Vascular access in dialysis patients remains both a critical link to survival and a significant source of morbidity. Currently, the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) vascular access guidelines recommend routine vascular access monitoring and encourage dedicated surveillance techniques to be used for early detection of access stenosis and prevention of thrombosis. There is a paucity of clear evidence supporting 1 surveillance technique over another. The purpose of this review is to describe the benefits and limitations of various surveillance techniques commonly used in the care of dialysis patients. Further studies in this area will be useful to determine the most appropriate combination of aggressive clinical monitoring and additional surveillance data to strike a balance between graft thrombosis and unnecessary vascular interventions.
