Brief summary

Whether intensive monitoring and preemptive intervention has an positive clinical effect on arterio-venous fistula (AVF) maintenance is a new issue in hemodialysis (HD) patient management. This study aims to explore the clinical value of intensive monitoring and preemptive intervention on AVF, so to decide the best follow-up items and frequency.

Interventions

OTHERIntensified Monitoring

Apart from clinical assessment, use non-invasive devices to check for the haemodynamic consequences of stenosis by measuring Qa, using either indicator dilution techniques or duplex ultrasound every month.
