Effect of Salvia Miltiorrhiza Injection in Patients With Autologous Fat Grafting to the Breast: A Preliminary Comparative Study.

[BACKGROUND] Salvia miltiorrhiza (SM) is an herb used in Chinese medicine formulations for promoting blood circulation and minimizing vascular stasis. It has been successfully utilized in treating cardiovascular diseases, such as atherosclerosis, thromboembolism, and angina.

[OBJECTIVES] The authors sought to study the effect of SM injections in autologous fat grafting to the breast.

[METHODS] Fifteen women who elected to undergo breast augmentation with autologous fat grafting were included in this study. Of these, 10 were given intravenous infusions of SM for 4 weeks perioperatively, and the remaining 5 did not receive herbal infusion. The increase in breast volume after fat grafting was measured in both the groups using a three-dimensional scanner. Breast tissue specimens were harvested just before the second fat injection procedure and were analyzed by the immunofluorescence staining test.

[RESULTS] All of the patients showed improvement in breast volume after fat grafting. The fat graft retention rate in the SM group was 60.06 ± 16.12%, whereas that in the non-SM group was 34.04 ± 11.15%. In addition, the SMG showed good breast morphology and absence of cyst formation.

[CONCLUSIONS] SM has the potential to increase the retention rate of fat grafts in breast augmentation.
