Granthamlet.co.ukadrenaline.5,6 In the late 1990s, ultrasound was introduced as a means of emulsifying fat prior to the aspiration phase, which decreased the amount of blood in the aspirate.1 First- and Second-Generation Ultrasound Devices Onelio Garcia, Jr, MD, FACSBoard-Certified Plastic Surgeon (Miami, FL) First-generation ultrasound devices utilized solid, blunt-tipped probes (4-6 mm) to deliver continuous ultrasound and fragment fat before evacuation. Second-generation ultrasound devices utilized 5 mm hollow cannulae to allow for simultaneous fat fragmentation and aspiration. However, the inner lumen of Lipoplasty is the most common cosmetic surgical procedure second-generation devices was restricted to a diameter of performed in the United States, yet ultrasound-assisted only 2 mm, limiting the aspiration function. In addition, access lipoplasty (UAL) only represents less than 20% of these incisions of up to 1 cm were required to accommodate the large procedures. Despite the well-documented advantages of UAL, instruments and skin protectors. Inadequate training and a poor concerns about complications remain a significant barrier. While understanding of these devices occasionally led to the excessive earlier iterations of internal ultrasound devices were associated application of ultrasound energy, which in some instances with blood loss, seroma, and burns, among other complications, adversely affected clinical outcomes and increased surgical third-generation devices, such as the VASER Lipo System, complications such as seromas, prolonged dysesthesias, burns, have clearly demonstrated advances in efficiency and safety, induration, contour irregularities, hyperpigmentation, cellulitis, including minimal blood loss and the safe extraction of large and prolonged swelling.5,7 While the complications associated volumes.1 The VASER Lipo System combines VASER technology with first- and second-generation devices are reportedly related refinements in energy delivery and instrumentation with to the excessive energy output associated with these devices improved clinical techniques to minimize tissue matrix trauma or to extended application, improvements made with third- and deliver the desired clinical outcome with maximum safety generation devices obviate these concerns.7 Third-generation UAL devices yield a cleaner aspirate with a higher percentage of supernatant fat.1 The VASER Lipo System: A Third-Generation Modern lipoplasty was introduced in the late 1970s by Dr. Yves-Gerard Illouz and featured the use of a blunt cannula accompanied by high-vacuum suction to promote the fat The VASER Lipo System, a third-generation UAL device, was extraction.3 In the late 1980s, Jeffrey A. Klein described the designed to improve safety and efficiency, reduce complications, tumescent technique, which added both high-volume fluid and and allow for faster patient recovery.5 VASER probes are a local anesthetic. These additions allowed the procedure to be constructed with a proprietary, solid, side-grooved design moved to an outpatient surgery setting with only intravenous that redistributes ultrasonic energy from the tip to the region sedation, rather than general anesthesia, and blood loss was reduced to 8% — 30% of total aspirate.1,4 However, concerns about the high volume of fluid required and the potential toxicity of lidocaine led to the evolution of the lower-volume, super-wet technique. Using a 1:1 ratio of infiltrating solution to estimated aspirate significantly lowered blood loss to a single digit percentage of the total aspirate.1 Some have advocated for increasing the ratio to between 3:1 and 6:1, aiming to achieve significant tissue turgor.5 However, while the appropriate use of wetting solution reduces blood loss and postoperative bruising and enhances patient comfort, overzealous use can result in systemic fluid overload, as evidenced by reported cases of pulmonary edema as well as toxic levels of local anesthetics and immediately proximal. This results in a 50% lower energy requirement as compared to older systems. The probes are blunt and pass through tissue easily with minimal trauma. Minimizing Several studies have explored the safety and efficacy of ultrasound output provides greater tissue fragmentation while lipoplasty with the VASER Lipo System as compared to traditional decreasing the probability of complications.
