Summary
This study introduces a new method for reconstructing traumatic soft tissue defects using mechanically processed microfat enriched with stromal vascular fraction (SVF). The technique shows promise for wound healing and defect closure.
Area of Science:
- Regenerative Medicine
- Plastic Surgery
- Tissue Engineering
Background:
- Traumatic soft tissue defects present reconstruction challenges due to tissue loss and poor vascularity.
- Adipose tissue is a viable autologous source, and stromal vascular fraction (SVF)-enriched microfat can be prepared intraoperatively without enzymes.
- Current methods for managing these defects are often complex and require specialized facilities.
Purpose of the Study:
- To present a standardized clinical protocol for processing autologous adipose tissue into SVF-enriched microfat for injection into traumatic soft tissue defects.
- To evaluate the feasibility and preliminary outcomes of this minimally manipulated microfat grafting technique.
- To offer a practical solution for defect reconstruction in settings lacking advanced laboratory capabilities.
Main Methods:
- Manual harvesting of adipose tissue from the thigh or abdomen under low negative pressure.
- Mechanical processing including fragmentation, syringe-to-syringe emulsification, filtration, and centrifugation to obtain SVF-enriched microfat.
- Intraoperative injection of microfat into wound cavities in a multilayered pattern, followed by serial clinical evaluation and photographic documentation.
Main Results:
- The protocol demonstrated progressive wound contraction and complete epithelialization within 4-8 weeks in a small patient cohort.
- The technique was associated with no major complications.
- The method proved to be a feasible intraoperative approach, suitable for various clinical settings.
Conclusions:
- Mechanically processed SVF-enriched microfat offers a practical, minimally manipulated option for managing traumatic cavity-type soft tissue defects.
- This protocol provides a foundation for further controlled studies on microfat grafting for reconstructive purposes.
- The technique is particularly valuable for resource-limited settings or when enzymatic processing is unavailable.
