A Case of Chronic Expanding Hematoma 15 Years after Breast Augmentation: Reconstructive Augmentation with Cultured Adipose-Derived Stem Cell-Enriched Fat Injection after Removal

Abstract

 Silicone breast implants (SBIs) are one of the main options for breast reconstruction and cosmetic breast augmentation; however, late complications, such as delayed hematoma, have been reported.
 We report a case of a 51-year-old woman who presented to our hospital 15 years after breast augmentation with silicone breast implants with the chief complaint of slow progressive swelling of the right breast. After examination, implant removal was performed due to implant breakage and hematoma. Thereafter, she underwent two additional cultured adipose-derived stem cell-enriched fat injections as revision breast augmentation. Postoperatively, the breast morphology was excellent, and the patient was highly satisfied with the results.
 Our findings suggest that fat injections are a treatment option for reconstruction after SBI removal because they are minimally invasive and cause little physical burden on the patient. Cultured adipose stem cell-enriched fat injections may also be an option for patients with the appropriate indications, based on their physical and social background.
