Objective: Autologous fat transplantation is gaining increasing importance alongside breast reconstruction using implants. It offers a viable alternative for breast reconstruction, especially in cases with complications following implants, such as capsular contracture. Until now, the unpredictable survival rate of fat tissue in lipofilling has been a challenge. We present a new method, the Cell-Enriched Lipotransfer (CELT), to address this issue.
Materials/Methods: Cell-Enriched Lipotransfer (CELT) is a simple technique for fat harvesting, processing, and reinjection. The fat tissue harvested via water-assisted liposuction (WAL) is processed using centrifugation and a shear-force-based technique to produce a highly concentrated, pure final product with a high number of adipose-derived stem cells, the Cleaned and Enriched Lipid Tissue (CELT). The fat graft survival rate was monitored pre- and postoperatively using 3D volumetric data. The follow-up period was 6 months.
Results: Over the past five years, the application of the CELT in 400 fat grafting procedures has significantly improved fat graft survival rates. The 3D volumetric data, measured preoperatively and 6 months postoperatively, showed a consistent survival rate of over 90% of the injected volume.
Conclusion: Processing the fat tissue harvested with water-assisted liposuction using the CELT technique resulted in a significantly improved fat graft survival rate. This high survival rate enables successful breast reconstruction with autologous fat following implant removal.
