Overview
Peripheral artery disease (PAD), vascular disease of atheromatous origin, is a frequent pathology, with a steady and significant increase in prevalence over the last decades. It has various symptoms ranging from mild arterial claudication to critical limb ischemia. The critical ischaemia stage in PAD is defined by rest pain or trophic disorders and is a special situation because of the number of cardiovascular deaths at 1 year (25%), 60% at 5 years and acute ischaemic recurrence at 1 year (25%).
It is a medico-surgical pathology. A haemodynamic marker is needed to monitor patients, as it is predictive of limb progression, cardiovascular events and mortality. The Systolic Rise Time (SRT) of the plantar footpad is a recently described haemodynamic measurement of proven value in the diagnosis of PAD. The aim of this study is to show the prognostic value of the Systolic Rise Time on Major Adverse Limb Events (MALE).
Eligibility
Inclusion Criteria:
- patients at least 18 years old,

- followed or send to CHU Amiens Picardie, and eligible to chirurgical revascularization.
Exclusion Criteria:
- with non atherosclerosis arteriopathy,
- ineligible to the gold standard treatment such as the chirurgical revascularization,
