The Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) threatened limb classification more comprehensively describes the extent of limb threat in patients with chronic limb-threatening ischemia than many previous classification systems. Several centers have published 1-year amputation rates stratified by WIfI clinical stage. Stage 1 limbs have the lowest amputation risk, Stage 4 limbs have the highest, and Stages 2 and 3 have an intermediate risk. As WIfI clinical stage increases, wound healing time is longer, 1-year wound healing rate is lower, and reintervention rate, hospital costs, length of stay, and readmission rate all increase.
