Society for Vascular Surgery Wound, Ischemia, foot Infection (WIfI) score correlates with the intensity of multimodal limb treatment and patient-centered outcomes in patients with threatened limbs managed in a limb preservation center

In patients treated aggressively for limb salvage, WIfI stage correlated with intensity of multimodal limb treatment and with limb salvage and patient-centered outcomes at 1 year. Revascularization improved limb salvage in severe ischemia. These data support the Society for Vascular Surgery WIfI system as a powerful tool to risk-stratify patients with threatened limbs and guide treatment.
