Successful hemodialysis is dependent on high unimpeded blood flow. Arteriovenous grafts are notorious for access stenosis, a precursor for access thrombosis. Access surveillance techniques are available and in observational studies have been superior to clinical monitoring for the detection of access stenosis and subsequent prevention of thrombosis in arteriovenous grafts. However, in prospective randomized controlled studies, these surveillance techniques have not been superior to clinical monitoring in reducing access thrombosis and or prolonging access survival. Presently, routine surveillance should not be performed until it can be proven to be effective at prolonging thrombosis free graft survival.
成功的血液透析依赖于高且通畅的血流量。动静脉移植物因通路狭窄而声名狼藉，通路狭窄是通路血栓形成的先兆。有可用的通路监测技术，并且在观察性研究中，这些技术在检测动静脉移植物的通路狭窄及随后预防血栓形成方面优于临床监测。然而，在前瞻性随机对照研究中，这些监测技术在减少通路血栓形成和/或延长通路存活时间方面并不优于临床监测。目前，在能够证明常规监测可有效延长无血栓移植物存活时间之前，不应进行常规监测。
