Case Reports of Adipose-derived Stem Cell Therapy

With the gradual increase of cases using fillers, cases of patients treated by non-medicalprofessionals or inexperienced physicians resulting in complications are also increasing. Weherein report 2 patients who experienced acute complications after receiving filler injectionsand were successfully treated with adipose-derived stem cell (ADSCs) therapy. Case 1 wasa 23-year-old female patient who received a filler (Restylane) injection in her forehead,glabella, and nose by a non-medical professional. The day after her injection, inflammationwas observed with a 3×3 cm skin necrosis. Case 2 was a 30-year-old woman who receiveda filler injection of hyaluronic acid gel (Juvederm) on her nasal dorsum and tip at a privateclinic. She developed erythema and swelling in the filler-injected area A solution containingADSCs harvested from each patient’s abdominal subcutaneous tissue was injected intothe lesion at the subcutaneous and dermis levels. The wounds healed without additionaltreatment. With continuous follow-up, both patients experienced only fine linear scars 6months postoperatively. By using adipose-derived stem cells, we successfully treated theacute complications of skin necrosis after the filler injection, resulting in much less scarring,and more satisfactory results were achieved not only in wound healing, but also in esthetics.
