Effects of aspiration time on immediate viability of adipocyte cell in ultrasound-assisted liposuction (UAL) and in traditional suction-assisted lipectomy (SAL)

Abstract

We aimed to determine the effect of aspiration periods following liposuction procedure on vascular structures, fibrocollagenous tissues and viability of adipose cells at different minutes, respectively in UAL and SAL. Abdominoplasty materials were divided into two equal parts from middle following excusion during the operations. Traditional SAL was performed to the right part of the abdominoplasty materials therewithal. Each side of the material was then divided into five parts enumarated from one to five and aspiration procedure time for each area was defined according to this ranking. The aspiration periods for each area were as follows: the transition intervals of 30 seconds between each zone were calculated as preoperative preparation time for surgical equipment in every area, and for discharging the lipoaspirates from collecting container. Red blood cell amount, a rate of degeneration in vasculary tissues, adipocyte cell amount with nuclear conformation, a rate of septal structure loss in fibroblast cells and septal fibroblast amount were the histopatological parametres of the study which observed and analysed by the pathologists. Based on the results of statistically analysis we proved that obtaining more surviving fat graft is possible by keeping aspiration period less than 2 minute in operation zone. In case of elongation of stated period clinical accomplishment of fat graft application reduces due to the downward of viable adipocyte cell amount and accelerating injury on tissues. Consequently, keeping the aspiration duration less than two minutes in planned liposuction area in both liposuction methods is favourable for providing maximum viable autologous fat graft.
