Preliminary results of alternative treatment for postmastectomy pain syndrome: stromal vascular fraction-enriched fat grafting

Postmastectomy pain syndrome (PMPS) is defined as chronic lasting more than 3 months after surgery. PMPS reduces the quality of life for patients and affects their daily life. Although pathogenesis has not been clearly elucidated, it strongly suggestive neuropathic caused by damage to intercostobrachial nerve. While previous studies have used stromal vascular fraction (SVF)-enriched fat grafts in with neuralgia, few PMPS. Therefore, present study evaluated use SVF-enriched fat, which includes adipose-derived stem cells good differentiation capacity, improve reduce pain. In three patients, was mixed concentrated SVF using a centrifuge injected into primary sites. After surgery, all cases, subjective scale score decreased significantly over time.
