[Intermittent claudication and critical limb ischemia : from diagnosis to management].

In case of atheromatous disease, the practitioner should be part of a multidisciplinary decision due to the associated comorbities. The angiologic assessment is of paramount importance in the diagnosis of peripheral artery disease even when the diagnosis seems clear. Unfortunately the patient is very often straightforward sent to radiological investigations who are faster. In all stages of peripheral artery disease, the medical treatment should be tried first except in case of critical limb ischemia where an invasive approach must be performed for revascularisation. In case of lifestyle-limiting symptoms and only after failure of medical treatment a revascularisation strategy is then indicated.
