Treatment CLI Nonrevascularizable Lower Limb With Cell Therapy

It has been demonstrated the feasibility, safety and effectiveness of mesenchymal stem cells derived from lipoaspirate for treating various pathologies fistula. With this project we will address a study population with critical ischemia of lower limbs without possibility of revascularization, either by technical criteria (no intervention possible to compensate for the lack of irrigation of a limb) criteria or risk / benefit (intolerable surgical risk for the type of intervention required). It will almost always elderly patients with multiple comorbidities and high surgical risk who have a lower limb ischemia in critical degree, with very high probability of major amputation in the short term or immediate. Hypothesis: mesenchymal stem cells obtained by lipoaspirate expanded "ex vivo", are capable of promoting angiogenesis de novo to improve critical limb ischemia lower nonrevascularizable a safe manner
