Clinical use
AVF Maturation interpretation support
Ultrasound support for AV fistula maturation using flow, vein diameter, depth, and usable segment length.
- Classic Rule-of-6 support uses flow >=600 mL/min, vein diameter >=6 mm, depth <=6 mm, and a usable straight segment >=6 cm.
- If you calculate flow from diameter and time-averaged mean velocity, the estimate assumes a circular lumen and representative mean velocity sampling.
