This is one of the few such operations performed in Europe on the cardiovascular system using adult stem cells. It is now clear that it will not be necessary to amputate the woman’s leg. 

The operation was performed on September 23 on a woman who risked having her leg amputated. A lack of oxygen present in the tissues due to an ischemia that was preventing blood permeation, caused tissue degeneration and death. Normally, said the doctors, for patients with these types of problems there is no alternative to amputation because ischemia and tissue death are irreversible. The doctors decided to try a new approach, using stem cells from the same patient to restore blood circulation in the leg. During the operation, the doctors isolated progenitor cells of the blood vessels from the patient’s bone marrow, then they immediately injected them into the patient’s leg. Once injected, the cells began to multiply, generating new blood vessels that allowed oxygen to reached the tissue, avoiding cell death.

The project, approved by the Catholic University’s Ethics Committee, was financed by the university. Today, said doctors, the patient is in good condition and has returned home. She is periodically inspected as an outpatient and the results are encouraging. “She no longer has pain typical of gangrene, the temperature of her leg is normal, and she has even started to walk.” d in Europe on the cardiovascular system using adult stem cells.
