Diagnosis / Prognosis: Platelet function testing
The investigators will test platelet reactivity at the beginning and midpoint of the first year after revascularization

Diagnosis / Prognosis: Vascular ultrasonography
The investigators will test bypass graft and stent patency at 30 days, 6 months, and 1 year.

Summary
Brief summary
The presence of foot symptoms at rest or tissue necrosis in patients with peripheral artery
disease is a medical urgency and represents a state of critical limb ischemia (CLI) where the
risk of amputation, in the absence of revascularization, is high. No trial conducted to date
in peripheral revascularization has determined the effect of diabetes on mechanism of
revascularization failure. Therefore, this trial represents a unique opportunity to
investigate the mechanisms by which diabetes affects surgical and endovascular
revascularization procedures with the long-term goal of improving outcomes in CLI.
