Evaluation of Local Capillary Blood Lactate in Chronic Critical Ischemia of Lower Limb Before and After Revascularization

Evaluation of Local Capillary Blood Lactate in Chronic Critical Ischemia of Lower Limb Before and After Revascularization.

Evaluation of a new biological criterion, the local capillary blood lactates to optimize the management of patients with chronic critical ischemia requiring revascularization fast. Potential use in terms of capillary blood lactate as a diagnostic indicator of recurrent ischemia in a limb revascularized.

Inclusion Criteria:

• Ischemia Chronic critical lower limb revascularization procedure requiring fast.
• Written consent informed patient age greater than or equal to 18

Exclusion Criteria:

• Presence of an inflammatory or infectious (erysipelas) in the ischemic member.

• Patients at risk for diabetic foot ie, as defined by the HAS (preventing diabetic foot, 2007)

  • presence of sensory neuropathy, and / or
  • foot deformities (hallux valgus, hammer toes or claw, prominence of the metatarsal heads), and / or
  • history of foot ulceration, and / or
  • antecedent of one of these factors (ie antécedant diabetic foot).

• Necrosis of the toes.

• Participation in another clinical research protocol.

• Presence of peripheral arterial disease in the bilateral upper limbs.

• Patient in shock whatever the cause.

• Presence of hepatic failure.

• Too impaired general condition (bedridden, dementia, ...)

• Refusal of the patient to participate in the study

• Protected patients
