Society for Vascular Surgery limb stage and patient risk correlate with outcomes in an amputation prevention program

Among patients hospitalized with limb-threatening conditions and treated by a multidisciplinary amputation prevention team, PIII risk correlates with mortality whereas WIfI stage strongly predicts initial hospital duration of stay, and key mid-term limb outcomes. Surgical revascularization performed best in the limbs at greatest risk (WIfI stage 4), and autogenous vein bypass was the preferred conduit for open bypass. These data support the use of WIfI and PIII as complementary staging tools in the management of chronic limb-threatening ischemia.
