Liposuction and VASER.

VASER is a fat pretreatment device based on the emission of pulsed or continuous ultrasound energy to emulsify fat before its aspiration by means of suction-assisted lipoplasty or power-assisted lipoplasty. If compared with previous generation UAL machines, it carries important technologic advances that focus on the safety and efficiency of the process. VASER is the result of improvements in surgical instrumentation and technique, proper use of wetting solutions, and knowledge about the best use of ultrasound for fat fragmentation. With its thinner cannulas and decreased use of ultrasonic energy, it allows greater emulsification of fat, creates more tunnels, diminishes the operative time, preserves vessels and nerves, and causes less pain and hematomas.

Cutis marmorata resemblance after liposuction.

Liposuction is a safe method for the treatment of lipodystrophy. It gives good results in relation to body contours, especially when the superficial and deep layers of the superficial fascia are aspirated. The authors present clinical cases of female patients who underwent liposuction of the abdomen, flanks, and back in which superficial and deep liposuction was used. In the immediate postoperative period, these patients presented a skin pattern of marbled appearance, involving rosy-purplish stains intermingled with other whitish stains on the skin in the areas subjected to surgery and resembling the cutis marmorata described in the literature. Even 1 year after the operation, the stains had not receded. The literature mentions cases of cutaneous necrosis provoked by a temperature increase induced by liposuction cannulas. This trauma said to be the determining factor for local lesions of the subdermal plexus. However, no cases involving lesions of this plexus attributable to mechanical trauma from cannulas are cited. According to several authors, it is important during superficial liposuction to maintain a strip about 1 cm thick under the deep dermis for the preservation of the arterial plexus of the skin. This would avoid the formation of a skin pattern resembling cutis marmorata.
