A New Technology for Liposuction and Fat Transfer
A SUPPLEMENT TO PSP A New Technology for Liposuction and Fat Transfer Hydrasolve® Gets the Only FDA Nod for Fat Transfer BY WENDY LEWIS O ver the last few years, autologous fat transfer has experienced increasing attention globally for aesthetic and reconstructive procedures. There is significant interest among plastic surgeons in using fat for breast reconstruction, as well as for aesthetic breast augmentation and additional treatment options. Historically, however, there have been technical challenges that have made it difficult to standardize treatment protocols and outcomes. In April 2013, HydraSolve® by Andrew Technologies LLC received FDA 510 (k) clearance for Autologous Fat Transfer, so that the adipose tissue harvested during a HydraSolve® liposuction procedure can be reinjected into the same patient for rejuvenation or augmentation. No other liposuction device has been FDA cleared for this use. This marks a significant development for HydraSolve®, which may offer clinical advantages to expand treatment options for patients. As Dr. Mark S. Andrew, Chief Scientific Officer of Andrew Technologies, explains, “HydraSolve® is an energy assisted liposuction system that combines natural saline solution with low levels of pressure and thermal energy to liquefy only targeted fat tissue. Because fat tissue is liquefied, the cutting of fat by forceful thrusts of the cannula is no longer required. The specially designed HydraSolve® cannula has aperture edges that have a rounded radius of curvature that do not cut tissue. The energized saline stream inside the cannula liquefies targeted fat tissue while preserving blood vessels, nerves and connective tissue integrity.” What is HydraSolve®’s point of difference? “What makes it unique is that it is a low-energy system which achieves true target tissue specificity, allowing liposuction to be done in a totally new manner that is gentler, less traumatic and more October 2013 PlasticSurgeryPractice.com PHOTOS COURTESY OF CHRIS GODEK, MD 1 year post implant exchange, nipple reconstruction, and 6 months after 350 cc of HydraSolve fat grafted to each breast. precise. The gentleness is also beneficial for fat grafting,” says Andrew. Only available currently to select board-certified aesthetic plastic surgeons in the U.S., HydraSolve® is an innovative liposuction technology that features a gentler, more efficient and precise method of fat removal. Plastic Surgeon Chris Godek in Toms River, N.J., lead clinical investigator says, “The system combines natural saline solution with low levels of pressure and temperature to liquefy only the unwanted fat - while preserving blood vessels, nerves and other tissues. The advantages to patients are faster, smoother and more even fat removal, plus less discomfort, bruising, swelling and recovery.” FAT GRAFTING FOR BREAST SURGERY According to a recent study published in Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS), 70 percent of U.S. plastic surgeons have used fat grafting for breast operations. The study indicated that 88 percent of plastic surgeons who currently perform fat grafting to the breast use it for breast reconstruction techniques, and often apply fat grafting along with implants or flap procedures. The surgeons found fat grafting particularly useful for improving the shape of the breast, including reconstruction after lumpectomy for early-stage breast cancer. Nearly 90 percent of the surgeons use fat graft- PlasticSurgeryPractice.com ing for breast reconstruction, yet only 28 percent perform fat grafting to the breast for aesthetic augmentation. 55 percent use hand-held suction (a syringe) to harvest the fat, which is considered to be a very time-consuming process. Among the common concerns over the use of fat grafting to the breast are the lack of consistency of fat graft retention rates, and the prevalence of unreliable results. “Fat grafting to the breast, in the right hands, can achieve satisfactory results,” says Winter Park, FL Plastic Surgeon Jeffrey Hartog. For breast cancer patients seeking a natural reconstruction, HydraSolve® offers the first FDA cleared option to provide your own fat for transfer. “HydraSolve® may offer a more natural alternative for those who seek to reconstruct their breasts after cancer,” says Hartog. Hartog decided to add breast reconstruction with autologous fat into his practice when his own wife Michelle Hartog, RN was diagnosed with breast cancer. As she explains, “For me autologous fat transfer was the best choice after considering all the options.” Hartog has since performed numerous autologous fat breast reconstruction procedures. “I find fat to be simply the most natural approach to breast reconstruction, without additional scarring and significantly lower risk of complications,” he says. “HydraSolve® delivers very pure fat that is simple to process and injects easily into the breast tissue for reconstruction. We are still early in the adoption of this technology, but it appears to be a great option for fat transfer”. Fat grafting to the breast is not just about aesthetics anymore, according to Dr. Terence Myckatyn, Associate Professor in the Division of Plastic and Reconstructive Surgery, Washington University, St. Louis, MO. “We performed 180 liposuction and fat grafting combined cases in our practice last year – most are from breast defects after breast cancer,” he says. According to Dr. Bruce Van Natta of Meridian Plastic Surgeons in Indianapolis, IN, “I am fat grafting virtually everywhere I am operating. Using fat grafting post radiation reverses the changes of hard, fibrotic breasts, improves skin color, softens tissue, and some patients even get sensation back. Hands down, fat grafting is the most exciting development I’ve seen in 25 years in practice.” IMPROVED FAT HARVESTING AND PROCESSING Van Natta calls HydraSolve® a kindler, gentler form of liposuction; “I have found that HydraSolve® rapidly removes fat and produces a nearly bloodless fat layer of uniform particles that can be easily injected into breasts and other target tissues. It may be the best system I have used for autologous fat grafting.” “In our practice, the majority of cases that require liposuction also require fat grafting. One area where we use a lot of fat is in the breasts for reconstructive surgery. With fat grafting you are introducing liposuction to the reconstructive surgery population. The patients approach us for reconstruction, and liposuction is a bonus,” says Myckatyn. “When I heard that HydraSolve® is less traumatic to fat cells and more cells survive, I was interested. The big question surrounding fat grafting is that it is somewhat unpredictable – survival rates are 50-60 percent. If you are dealing with more living fat cells, you tip the balance in your favor to get more viable fat cells to survive,” Myckatyn says. “In our experience, HydraSolve® seems to be faster for large volume liposuction. October 2013 AFTER PHOTOS COURTESY OF CHRIS GODEK, MD BEFORE BEFORE AFTER PHOTOS COURTESY OF CHRIS GODEK, MD 6 months postop after HydraSolve® used to remove 250 cc from the flanks and thighs. 1 year postop after lower facelift and neck contouring performed with HydraSolve® to remove 25 cc from the neck and face. It combines viable fat cells with quicker harvesting which is beneficial for these larger volumes. The most remarkable thing is how clean and bloodless the fat looks, and how much less non-fat extraneous tissue there is. But we do not have long term data on how well the fat is retained. Early results show good retention, but the longest case we have is now four months out. So far, the harvested fat appears to be cleaner.” According to Godek who has been using HydraSolve® for over three years, “I have done 70 cases of liposuction, and 20 of those also involved fat grafting. I have used HydraSolve® everywhere, for the face, breasts, buttocks, and for contour irregularities post liposuction.” “What I like most is that it is an easier harvest, less traumatic, less bleeding and bruising. The fat comes out cleaner with less contaminants. The fat that is removed is virtually bloodless,” says Godek. Myckatyn agrees. “We don’t have vast experience yet, but it seems that patients are at least at the lower end of the spectrum of pain, bruising and swelling,” says Myckatyn. is less trauma, it is easier on the surgeon, and we see minimal blood loss. This is where I believe it will be the best fit.” Van Natta adds, “For large volumes, I wouldn’t want to use anything else. There is nothing I am aware of that can remove large volumes of fat as safely and efficiently as HydraSolve®. I also offer it to abdominoplasty patients to contour the flanks and hips. When you explain that it may save an hour in OR time and they will have a faster recovery, patients are willing to pay a premium.” Godek concurs that HydraSolve® speeds up a case. “I can extract fat twice as fast so it saves me OR time. There is less swelling, pain and bruising, and I get a better result in my opinion. I tell my patients they can be in a bathing suit in three to four weeks,” he says. In Godek’s view, the next goal would be to integrate HydraSolve® in a contained system instead of collection in a secondary sterile container. Andrew Technologies has the potential to make that happen in the not too distant future.
