Ultrasound Monitoring to Detect Access Stenosis in Hemodialysis Patients: A Systematic Review

There was no evidence that screening with access blood flow measurements or Doppler ultrasound is of benefit to patients with grafts. Access blood flow screening may prevent access thrombosis in arteriovenous fistulas, but may not reduce the risk of access loss or extent of resource use. These findings have implications for clinical practice guidelines and for future research.
