Figure 10. Preferred initial revascularization strategy for
infrainguinal disease in average-risk patients with
suitable autologous vein conduit available for
bypass
Revascularization is considered rarely indicated in limbs at low risk (Wound, Ischemia, and
foot Infection [WIf I] stage 1). Anatomic stage (y-axis) is determined by the Global Limb
Anatomic Staging System (GLASS); limb risk (x-axis) is determined by WIf I staging. e
dark gray shading indicates scenarios with least consensus (assumptions – inflow disease
either is not significant or is corrected; absence of severe pedal disease, ie, no GLASS P2
modifier).
Average risk is defined as estimated perioperative mortality <5% and estimated 2 yr
survival >50%.
