title: Noninvasive methods to identify early vascular access dysfunction.
abstract: A functional vascular access is of critical importance to the hemodialysis patient, the patient's healthcare providers, and the hemodialysis treatment center. A poorly functioning or thrombosed vascular access can lead to increased morbidity, hospitalization, length of stay, and cost. This article reviews the increasing evidence supporting surveillance of arteriovenous (AV) hemodialysis access and the various strategies and techniques available for detection of a failing access.
