Fig 2 The annual costs per living patient are demonstrated during the 10-year interval after the initiation of various management strategies: (A) strategy 1 (local wound care); (B) strategy 2 (primary amputation); (C) strategy 3 (surgical bypass with surgical revision); (D) strategy 4 (surgical bypass with endovascular revision); (E) strategy 5 (purely endovascular intervention); and (F) strategy 6 (endovascular intervention, surgical bypass for failure).

Fig 3 The incremental costs (in 2009 U.S. dollars) and incremental benefits (quality-adjusted life-years) are demonstrated for strategy 4 (surgical bypass with endovascular revision) compared with strategy 1 (local wound care with amputation as indicated).

Fig 4 Cost-effectiveness acceptability curves are shown for critical limb ischemia (CLI) management strategies compared with strategy 1 (local wound care). The probability of strategy 4 (surgical bypass with endovascular revision) being a cost-effective alternative increases as the willingness-to-pay threshold in U.S. dollars (USD) surpasses $39,255 per quality-adjusted life-year.
