Brief Summary:

Aim: to value the safety and efficacy of local intramuscular administration of immunoselected autologous endothelial progenitor cells in the treatment of critical limb ischemia in patients without revascularization options.

Primary goal: to value the feasibility of mobilization, harvesting, immunoselection and auto transplantation of endothelial progenitor cells.

Secondary goal: to value the efficacy of local administration of autologous endothelial progenitor cells in the treatment of critical limb ischemia

Arm Intervention/treatment
Experimental: single arm: autologous EPCs Other: Endothelial progenitor cells intramuscular implant
After marrow stimulation the CD133+ cell count was monitored daily. Each leukapheresis collection was diluted with 10% acide citrate dextrose (ACD-A)CD133 immunomagnetic cell selections were performed . After loco-regional anesthesia and below the knee cutaneous disinfection, 45-48 ml of autologous CD133+ saline solution suspension is administered intramuscularly with 1 ml deep injection through 18G needle. The injections were so allocated: 10 ml in the anterior compartment of leg, 10 ml in the superficial posterior compartment, 10 ml in the deep posterior compartment, 10 ml in the lateral compartment and the remaining part in the foot.
Other Name: Cell therapy in critical limb ischemia.

Secondary Outcome Measures :
  1. Pain relief [ Time Frame: 3-6-12 months ]
    Monitoring the use of pain killing drugs

  2. ulcer healing [ Time Frame: 3-6-12 months ]
    monitoring the healing of trophic lesions
