  • Limb perfusion assessment is important for the timely diagnosis of critical limb ischemia (CLI) and may help to reduce unnecessary invasive procedures in patients with adequate blood flow.
  • This statement reviews the limitations of current methods of perfusion assessment and discusses newer techniques including transcutaneous oximetry (TcPO2), near-infra-red spectroscopy, and hyperspectral imaging.
  • The importance of incorporating perfusion assessment into the care of CLI patients is also highlighted.
