Acute ischemia of the lower limb (AMI) is a life-threatening emergency that threatens the functional prognosis of the limb. Depending on the clinical presentation and the anatomy of the patient, several therapeutic approaches can be considered: open surgery, endovascular surgery, hybrid surgery or amputation if revascularization is not feasible. The data in the current literature do not allow to clearly establish which therapeutic approach is the most adapted to the patient.

Inclusion Criteria:

• Age greater than 18 years, regardless of gender.
• Diagnosis of AMI defined according to the Rutherford classification (2). AMI may involve one or both lower limbs.
• Be able to understand and give free and informed consent (non-opposition) to participate in the study
• To be affiliated to the social security system
• Not to object to participating in the study (collection of non-objection)

Exclusion Criteria:

• Voluntary discharge of the patient: opposition to the use of the data (withdrawal of the non-objection)
• Termination of the study by decision of the sponsor or investigator.
