Study Shows Fat Removed with Vaser is Viable in Fat Transfer


Fat removed with Vaser shown to have a nearly 80% survival rate.

A new study from the University of Pittsburgh has found that fat removed with the Vaser Lipo device can be used in fat transfer surgeries. The study found that patients have nearly 80% volume retention, which is great news for patients who want to remove fat from one area of their body and move it to another such as the buttocks or breasts.

In fat transfer procedures, fat is removed from one part of the body such as the thighs or stomach. It's then filtered and injected back into another area for added volume. It's a popular procedure amongst patients who seek a natural alternative to fillers and implants, and also those who want both liposuction and volume enhancement.

One of the problems many have found with fat transfer is that the fat doesn't survive and is flushed out of the body. Physicians began using special methods to remove fat that is to be used for transfer so that it is well preserved and the cells are still viable. Since Vaser uses ultrasound technology to break fat cells loose from surrounding tissues so they can be easily suctioned out, many felt that the damage to the cells would leave them ill-suited for use in transfer procedures.

Fat Transfer with Vaser Results of Dr. David Broadway

Many physicians were already using Vaser for fat transfer, and Denver Vaser provider and board certified cosmetic surgeon Dr. David Broadway was quoted in the THE Aesthetic Guide earlier this year saying, "Fat harvested mechanically has a clumpier, lumpier consistency, but fat harvested with Vaser has the consistency of a milkshake, which facilitates an even flow during re-injection.... This allows me to be more precise with my technique so I can sculpt more effectively."

Researchers looked at tissue samples from a patient who underwent a body contouring procedure to remove fat from the thighs and flanks with Vaser and suction-assisted liposuction (SAL). They then investigated the samples to find that there was little to no difference at the cellular level between the fat removed with Vaser and the fat removed with SAL. Results at six weeks showed approximately 80% of the filtered fat survived by volume, regardless of how it was removed. According to a press release from Sound Surgical Technologies, manufacturers of Vaser, "As a point of comparison, other studies have shown less than 5% of the water-jet assisted liposuction fat survived."
