Preoperative vascular mapping: Minimal arterial requirements for fistula placement

ArteryYounger Patients (Long Life Expectancy)Older Patients (Medium or Short Life Expectancy)
Radial artery1.5–2.0 mm (if RH+)>2.0 mm (if RH−)≥2.0 mm
Brachial artery2.5–3.0 mm (if RH+)>3.0 mm (if RH−)≥3.0 mm
  • RH+, presence of arterial response at the reactive hyperemia test; RH−, absence of arterial response at the reactive hyperemia test.
