SVF Breast Augmentation
別名: SVF豊胸術, SVF脂肪注入豊胸, エスブイエフ豊胸
SVF breast augmentation is breast fat grafting in which the injected fat is enriched with the patient's own stromal vascular fraction.
What does the 77.48% retention rate for SVF breast augmentation mean?
The 77.48% figure comes from a 2023 study in Annals of Plastic Surgery authored by SC301's representative director: among 384 women who had SVF-enriched breast fat grafting, the average retention measured in the left breast was 77.48% in the 102 patients followed to 18 months. It is a single-center, provider-authored result, not a general average for all SVF fat grafting, and should be read with its study design.

概要
The procedure combines liposuction, SVF isolation and fat injection in one operation. Published single-center series report retention rates around three-quarters of injected volume at 6–18 months, with retention influenced by cell number, breast tissue softness and postoperative factors; these are provider-authored studies and independent controlled data are limited. Patients should confirm the regulatory status of SVF processing at the institution.
