What happens during the fat purification process for a BBL fat transfer?

Question

Is the blood removed from the fat? Are damaged cells thoroughly removed? Is a significant amount of the fat lost in this process?

Vivek Bansal, MD · Answer

Thank you for your question. This removes the liquid and blood. Then, just the fat cells are left. They survive better free of old blood. Very little fat is lost. I hope this helps!

I use gravity sedimentation protocol to allow only the fat to be injected.  This process also causes the least amount of damage to the fat cells. Find an

Indeed, there are various ways of
"processing" the fat after it is harvested. Basically, time is needed
for the liquid portion of the aspirate to separate, and I think a gentle
antibiotic washing is helpful. However, in my opinion, the critical part of fat
survival depends on the injection technique. One must inject with many passes
through a small cannula so the cells are deposited in very small aliquots. 
This allows the surrounding tissue's blood supply to grow in which determines
the percent of fat survival.

Most of the obvious blood and saline is removed from the fat mixture prior to injection. Each surgeon has a slightly different protocol for handling the fat, some will wash it with saline, some will dry it on gauze and some will re-inject everything they removed from the liposuction. Some will also centrifuge (spin) the fat to removed some more blood and oil. For fat transfer to the buttock, most of the visible blood and saline is removed prior to straining the fat. Roughly about 60% or so of the fat will survive if strained and injected properly. Consult with a plastic surgeon in person to see if you are a good candidate for this procedure.Best wishes,Dr.Bruno

I use gravity filtration.  I use tumescent liposuction to harvest the fat.  I feel I get good results that way and I think it minimizes damage to the fat cells.  The harvested fat is placed in a special container that allows us to separate the liquid from the fat.  The fat is then removed and injected into the areas to be treated.

Barry L. Eppley, MD, DMD · Answer

Most surgeons that perform BBL process the harvest fat is some manner which you are calling 'fat purification'. There numerous methods to do it and none have been shown to be necessarily better than another. It is just important some processing method of the lipo aspirate is used so excess liquids and blood is eliminated from the eventual injectate.

Thanks for writing,I agree with my colleagues, this operation is all about experience, and technique. Please find a Board Certified Plastic Surgeon who has a lot of experience with this operation. Good LuckStephen M. Dvais, MD, FACSGreen Hills Plastic Surgery

That's a great question! Just like in most of plastic surgery, there are many different techniques that we use. So first and foremost, when considering a fat grafting procedure, make sure your surgeon is board certified in plastic surgery and that he or she performs buttock augmentation regularly. Personally, I think buttock augmentation with fat grafting is a great procedure. Once fat is harvested (with liposuction), it is prepared on the back sterile table in the OR. The majority of oils, dead fat cells, serum and blood is removed gently, leaving behind healthy fat and fat stem cells. This fat is then grafted (injected) into the buttocks. For the fat to survice, it must be grafted with a meticulous technique to maximize survival. Some of the fat will not survive, but the presence of the stem cells will cause new fat to grow, enhancing the grafting success. There us no exact percentage of fat survival, but it likely around 70 - 80%. Fat that survives within the first 3-6 months will likely be permanent. Thanks!
