[Cryoanalgesia of the nerves of the feet in distal arteritis in the elderly].

Fifty limb salvages were attempted by using phenol sympathectomy combined with cryo-analgesia of foot nerves in patients with distal lesions. Cryo-analgesia does not interfere with walking and exercising and avoids oedema. Results were gratifying in patients with rest pain, and no gangrenous involvement: 80% of salvages. Very old patients (over 90 years) experienced satisfactory results in 60% of the cases. Even when a reconstructive procedure had failed previously, we achieved a 25% limb salvage rate. Thus cryo-analgesia under local anesthesia appears as a useful therapy for elderly patients with distal arterial disease.
