Introduction: the peripheral arterial disease of lower limbs is a common syndrome that affects a high percentage of world adult population and is associated to a decrease of the functional capacity. Objective: to determine the behavior of hematopoietic stem cells implantation in patients with chronic leg ischemia. Methods: a quasi-experimental prospective study was conducted in a sample of 159 patients aged over 40 years, who suffered from chronic leg ischemia. All of them had been treated at the angiology service of "Arnaldo Milián Castro" hospital and had undergone hematopoietic stem cells implantation. The study variables were age, sex, risk factors, pain at rest, pain-free time of walking, improvement of ischemic lesions, post-transplant major amputation and reoccurrence of severe ischemic manifestations. The evaluation criteria of the treatment were primary response (four weeks) and advanced (24 weeks), relapse and therapeutic failure Results: the most frequent symptoms before the implantation was the intermittent arterial claudication in less than 200 meter distance (IIb) and ischemic lesions (IV). After the implantation, an increase in the distance of intermittent arterial claudication was observed in more than 200 meter (IIa) distance. Therapeutic failure was just observed in patients who required a major amputation. Conclusions: the hematopoietic stem cells implantation in patients with chronic leg ischemia proved to be a good therapeutic alternative for the treatment of peripheral arterial disease, thus reducing index of amputations.
