Severe limb ischemia represents a critical condition, being associated with high morbidity and mortality rates. Patients with critical limb ischemia (CLI) require urgent initiation of interventional or surgical treatment, as restoration of the blood flow is the only way to ensure limb salvage in these critical cases.
