SVF-assisted Fat Grafting
يعرف أيضا باسم: الجزء الوعائي اللحمي, الكسر الوعائي اللحمي, حقن الدهون المدعم بالخلايا الجذعية, نقل الدهون المعزز بالخلايا الجذعية, اس في اف, SVF
SVF-assisted fat grafting (a form of cell-assisted lipotransfer) enriches the fat graft with stromal vascular fraction isolated from part of the harvested fat, with the aim of improving graft survival.
Is SVF fat grafting safe?
A 2026 literature review of autologous adipose-derived SVF in clinical use examined its safety profile across published studies. Reported adverse events are mostly those of liposuction and fat grafting themselves. Safety depends on sterile processing in a licensed facility and appropriate patient selection. Regulators warn against unapproved stem cell products, so verify the clinic's processing approvals.

نظرة عامة
Part of the liposuctioned fat is processed into SVF, which is mixed with the remaining fat before injection. Systematic reviews of cell-assisted lipotransfer report generally higher retention than conventional grafting in pooled analyses, but study quality, cell dose and measurement methods vary, and regulatory status of SVF processing differs by country. It is not a stem cell therapy in the sense of culture-expanded cells.
