Long-Term Clinical and Radiologic Results with Autologous Fat Transplantation for Breast Augmentation: Case Reports and Review of the Literature

THE BREAST JOURNAL, Issue 1 2006
Srinivas R. Pulagam MD
Abstract: Autologous fat transplantation was initially performed by plastic surgeons for improving facial and body contour depressions and scars. There has been long-standing interest in breast augmentation for cosmetic purposes and for the filling of defects from partial breast resection for breast cancer. In the 1980s, autologous fat transplantation for breast augmentation and symmetry gained popularity. We present two cases of autologous fat transplantation into the breast parenchyma that demonstrate the long-term clinical and radiologic results of this approach and to illustrate the potential caveats regarding breast cancer diagnosis in these patients. We also review the existing literature on the subject as it relates to long-term effects and complications., [source]

Viability of Preadipocytes In Vitro: The Influence of Local Anesthetics and pH

DERMATOLOGIC SURGERY, Issue 8 2009
MAIKE KECK MD
BACKGROUND Autogenous fat transfer with lipoinjection for soft tissue augmentation is a commonly used surgical technique. Abundant donor tissue availability and relative ease of harvesting have made autologous fat an attractive soft tissue filler. The overall reliability of this technique is often disputed, and different authors describe different results after autologous fat transplantation despite using similar techniques. In this study, we examined the influence of different local anesthetics commonly used in fat harvest and the pH of the anesthetic solution on the viability of harvested preadipocytes. METHODS AND MATERIALS Preadipocytes were incubated with 1% lidocaine, 1% articaine plus epinephrine 1:200,000, 0.75% ropivacaine, and 1% prilocaine or our standardized tumescent solution (1 L of 0.9% sodium chloride solution plus 25 mL of 1% articaine plus epinephrine 1:200,000 plus 25 mL of bicarbonate) for 30 minutes. Additionally, we incubated cells with the local anesthetics as described above but diluted 1:2 with phosphate buffered saline (pH 7.4). Viability was measured using trypan blue dying as well as propidium iodine staining and fluorescence-activated cell sorting analysis. RESULTS There are significant differences in the viability of preadipocytes under the influence of various local anesthetics. DISCUSSION Our data could partially explain the varying results after autogenous fat transfer. [source]
