Is the Lipoaspirate Volume Linked to an Increased Risk of Complications after Liposuction?

“…1 An odds ratio calculator that compares risk (really the seroma risk) in a patient with a body mass index of 25 or 30 versus a hypothetical patient with a body mass index of 50 is of little practical value, as extremely obese patients are not liposuction candidates. 7 Similarly, the calculation of odds ratios as high as 10,742.9 using as reference a fictitious patient with a body mass index of 15 and lipoaspirate volume of 0 is of questionable clinical usefulness. A figure plotting actual patient data would be more helpful than these calculated extrapolations.…”

“…6 When they do occur after liposuction, most hematomas and seromas are typically small and resolve spontaneously. 7 Is it possible that some patients in the authors' database had excisional procedures and the codes were not entered?…”

“…Currently, there are public misconceptions about the safety of liposuction, which has unfortunately led to state-specific regulations and even mandated limits on liposuction. [2][3][4][5][6][7][8][9] It was to address these misperceptions that we endeavored to develop an evidence-based response from our community.…”

Is There a Safe Lipoaspirate Volume? A Risk Assessment Model of Liposuction Volume as a Function of Body Mass Index

“…9,22,23 The current American Society of Plastic Surgeons guidelines defines 5000 ml of aspirate as large-volume liposuction that likely portends increased procedural risk, despite concluding that "there is no scientific data available to support a specific volume maximum at which liposuction is no longer safe." 24,25 Recently, the utility of lipoaspirate volume as a proxy for procedural risk has been questioned, as varying volumes of wetting solution may be infused with different amounts of fat removed in the same total lipoaspirate volume, depending on the technique used, a fact not adequately accounted for by simply quantifying liposuction volume. 4,9,26 Furthermore, in a prospective study of patients undergoing liposuction, Swanson described the deceptive nature of estimating blood loss based on the negligible levels of hematocrit found in lipoaspirate, which typically accounts for only 2 percent of the blood loss experienced during liposuction.…”

“…27 Nonetheless, current guidelines recommend that large-volume liposuction (>5000 ml aspirate) be performed in an acute-care hospital setting for proper monitoring. 24,25 Given limited empirical guidelines, plastic surgeons have relied on subjective estimates of the safe lipoaspirate volume based on a patient's medical condition, body mass index, concomitant procedures, and the potential physiologic consequences of liposuction. 24,25,28 The introduction and advent of individualized risk calculators such as the Breast Reconstruction Risk Assessment score underlines increased physician and patient demand for empiric and patient-centric data in an effort to capture more nuanced and quantitative measures of risk than typical population-based measures.…”
