Fat Graft Harvested via VASER liposuction is Suitable for Brazilian Butt Lift

Fat Graft Harvested via VASER Liposuction is Viable and Suitable for Fat Transfer in Brazilian Butt Lift Patients

Although there's clinical evidence of successful autologous fat transfer (AFT), such as in Brazilian Butt Lift, using VASER liposuction is readily available, no study has quantified adipocyte viability using standardized methods until recently.
  • The UAL system (VASER; Sound Surgical Technologies, Inc, Louisville, Colorado) was set at 60% amplitude in pulsed mode with vacuum aspiration of 15 in Hg or less.
  • Laboratory analysis included free lipid volume, viability via lipolysis and propidium iodide staining, and cytological analysis, including cell surface protein examination and hematoxylin and eosin staining.
  • The lipolysis assay revealed metabolically active adipocytes with a mean (SD) correlative viability of 85.1%
  • Direct measures of acute viability via propidium iodide staining resulted in a mean (SD) viability measure of 88.7%
  • Adipose tissue acquired via VASER liposuction is viable at harvest and isa suitable source for autologous fat grafts, especially for Brazilian Butt Lift.
  • Adiposed-derived stem cells (fat for fat transfer) obtained via VASER liposuction were of equal quality when directly compared with the current gold standard harvest method according to a study conducted by Duscher.   "UAL- and SAL-derived samples demonstrated equivalent ASC yield and viability, and UAL ASCs were not impaired in their osteogenic, adipogenic, or chondrogenic differentiation capacity."

Improvement of Diabetes after VASER Liposuction

Improvement of Diabetes after a VASER Liposuction

Recently, there has been a study conducted to examine the liposuction-induced metabolic changes with regard to release of major adipokines and insulin sensitivity in overweight male patients.

  • "To eliminate the confounding effects of postsurgical inflammation and to evaluate delayed metabolic effects, fasting blood was collected on the day of liposuction, within 1 to 2 months and more than 6 months after surgery."
  • "Both treatment groups (diabetic and nondiabetic patients) experienced similar postsurgical weight reduction with concomitant lowering of body mass index value at 1 to 2 months follow-up, which was sustained after 6 months from surgery."
  • "Improvement in insulin sensitivity at 1 to 2 months follow-up was observed ( p = .017 and p = .002, for diabetics and nondiabetics, respectively) and this change persisted over the next 4 months."
This study shows that there may be beneficial effects of VASER Liposuction in overweight diabetic and non-diabetic males by improving their insulin sensitivity.

Skin Retraction after VASER Liposuction

Skin Retraction After VASER Liposuction

A recent randomized clinical trial had shown that the VASER liposuction produced clinical significant skin retraction. 
  • "Regarding skin retraction, the VASER-assisted lipoplasty-treated side resulted in a statistically significant improvement in skin retraction of 53 percent relative to suction-assisted lipoplasty (17 percent per liter versus 11 percent per liter, p = 0.003) with 33 paired sites using a two-tailed t test. "
