Evaluation of Blood Loss in Third-Generation Internal Ultrasound-Assisted Liposuction.

Background: In large-volume liposuction procedures, one of the most important limitations of total lipoaspirate volume is blood loss. In this study, we aimed to determine the amount of blood loss in individuals who underwent a third-generation internal ultrasound-assisted liposuction (UAL).

Methods: Eleven female and eleven male participants with a mean age of 35.

Comparative analysis of blood loss in suction-assisted lipoplasty and third-generation internal ultrasound-assisted lipoplasty.

Background: Lipoplasty remains the most common cosmetic surgical procedure performed in the United States. In spite of its well documented clinical advantages, ultrasound-assisted lipoplasty (UAL) accounts for less than 20% of all lipoplasty procedures currently performed.

Objective: The purpose of this study is to determine the blood content of third-generation internal UAL aspirate and compare it to traditional lipoplasty aspirate.

Liposuction: review of the techniques, innovations and applications.

Liposuction is currently the most frequently performed aesthetic operation in the world. Despite its wide-spread popularity, it should nevertheless be stated that it is not trivial surgery, not always benign and not as safe as intimated in the glossy office brochures. Since the initial description of liposuction, numerous changes have taken place.

Ultrasound-assisted lipoplasty: a review of over 350 consecutive cases using a two-stage technique.

Ultrasound-assisted lipoplasty (UAL) was developed in Europe and South America. Its introduction into the mainstream of United States surgery in 1997 was initially received with great enthusiasm. Soon, however, anecdotal reports surfaced describing limitations and complications related to the emerging technology.

Laboratory and histopathologic comparative study of internal ultrasound-assisted lipoplasty and tumescent lipoplasty.

Despite the advantages of using internal ultrasound-assisted lipoplasty instead of the classic tumescent lipoplasty, such as reduced bleeding and tissue damage, the authors found no objective or comparative study of these techniques in humans. For this reason, they conducted a clinical study to determine the amount of bleeding and tissue damage caused by each of the techniques. A simple clinical assay was accomplished at the Jalisco Plastic Surgery Institute on seven female patients scheduled for abdominal lipectomy.

Comparative lipoplasty analysis of in vivo-treated adipose tissue.

A comparative histologic and chemical analysis was undertaken of adipose tissue treated in vivo with traditional, ultrasound-assisted, and external ultrasound-assisted lipoplasty. A series of six healthy women undergoing elective liposuction according to the superwet technique using a 1:1 infiltration ratio with the estimated quantity of fat to be removed was included in the study. Four separate regions on each patient were treated independently in vivo with traditional liposuction, internal ultrasound-assisted liposuction, or external ultrasound-assisted liposuction for 7 minutes.

External ultrasonic lipoplasty: an effective method of fat removal and skin shrinkage.

External ultrasonic lipoplasty is an effective method for the removal of localized fat and the fat due to moderate obesity. The ultrasound is externally applied and transmitted through the skin surface. The acoustic waves are selectively absorbed by previously injected tumescent fluid and fat.

Report from the conference on ultrasound-assisted liposuction safety and effects.

The authors report on the Ultrasound-Assisted Liposuction (UAL) Safety and Effects conference held in St. Louis, Missouri, in November 1998. The meeting was convened to discuss how internal UAL works (its physics and mechanisms of action), gain a basic knowledge of the interaction between acoustic energy and tissue, identify safety concerns potentially related to thermal effects and free radical production, and define future research questions.
