Chronic limb threatening ischemia (CLTI) is defined as ischemic foot pain at rest or non-healing foot wounds that is attributable to severe peripheral arterial disease (PAD).Revascularization is the cornerstone of therapy to relieve ischemic pain, prevent limb loss and preserve patient autonomy. Revascularization procedures often involve below-the-knee arterial disease in CLTI population. Dual antiplatelet therapy (DAPT, with aspirin, and clopidogrel) is recommended for at least 1-month after peripheral angioplasty. However, the exact duration of this DAPT remains controversial. Angioplasty of below-the-knee arteries is often followed by a longer period of DAPT, 3-months to one-year, due to a high risk of arterial thrombosis/stenosis.It will be the first trial on duration of DAPT in patients with below-the-knee angioplasty for CLTI, the end-stage of PAD

Amputation-free survival at 12 months
Amputation-free survival at 12 months, defined as time from randomization until major amputation (defined as above-the-ankle amputation) or death from any cause, whichever occurs first, for all subjects.
12 months
11-months of clopidogrel 75 mg/day
11-months of placebo of clopidogrel
After inclusion and randomization at one-month, the intervention group will receive clopidogrel 75 mg/day for 11 months and the control a placebo of clopidogrel/day for 11 months
After inclusion and randomization at one-month, the control group will receive a placebo of clopidogrel/day for 11 months
