Liposuction Safety July 17, 2020

There is no national database that tracks all complications for all procedures so any number is an estimate. Deaths may be reported to state agencies but the number of cases done is not reported anywhere so while we may have an estimated numerator, there is no accurate denominator, especially since a significant amount of liposuction cases are done by non-plastic surgeons in non-accredited facilities.

Some estimates from 20+ years ago had a death rate as high as 1 in 5000 liposuction cases, which is very high, but the methodology of the study was questionable.

The American Society of Plastic Surgeons maintains a registry of plastic surgery cases called TOPS (Tracking Operations & Outcomes for Plastic Surgeons) which is the largest database of plastic surgery cases. The American Society of Plastic Surgeons (ASPS) is the authority on patient safety and liposuction.

Based on this database, the attached papers[1] [2]did not find any deaths in about 4,500 cases done by plastic surgeons. However, non-plastic surgeons are not included in this study.

While liposuction is considered very safe, not all liposuction surgery is equal. Small volume liposuction (<1000 cc) done awake is different from large volume liposuction (>5000 cc, in some cases 10,000 cc) done with anesthesia and a hospital stay. Relative comparisons are hard to make since you have to account for other variables (ASA status, co morbidities, etc…) which is nearly impossible to do without data. The reported 1 in 10,000 death rate for liposuction is a reasonable estimate (this figure does not differentiate between reconstructive liposuction for lipedema and cosmetic liposuction).

In the (Chow I., et al., 2015) study listed above, sixty-nine of 4534 patients (1.5 percent) meeting inclusion criteria experienced a postoperative complication. Their conclusion was that: Liposuction by board-certified plastic surgeons is safe, with a low risk of life-threatening complications. Traditional liposuction volume thresholds do not accurately convey individualized risk. The authors’ risk assessment model demonstrates that volumes in excess of 100 ml per unit of body mass index confer an increased risk of complications.

Several studies support higher risks associated with higher BMI.[3] The Safety of Aesthetic Surgery in the Overweight Patient (Gupta V et al., 2016) paper concluded:

Overweight (BMI 25-29.9) and obesity (BMI ≥ 30) are both independent risk factors for post-operative infection and VTE in aesthetic surgery.[4]

Of the procedures analyzed, liposuction had the fewest number of complications.

  • Abdominoplasty                                            3.5%
  • Liposuction                                                     0.9%
  • Lower body lift                                               8.8%
  • Combined breast and body procedures    4.2%

However, for all procedures complications were significantly higher in overweight patients.

In the (Habbema L, 2009) paper on safety he concludes:

RESULTS In a series of 3,240 procedures, no deaths occurred, and no complications requiring hospitalization were experienced. In nine cases, complications developed that needed further action.

CONCLUSIONS Liposuction using exclusively TLA is a proven safe procedure provided that the existing guidelines are meticulously followed.”[5]

Note that several of the studies apply to all plastic surgeries or all aesthetic procedures, not just liposuction. However, since the majority of lipedema patients also have obesity these issues are very relevant.

Death and other complications are clearly spelled out on the ASPS Liposuction Consent document available below.

ASPS List of complications[6]

  1. Liposuction risks include:
  2. Anesthesia risks
  3. Bruising
  4. Change in skin sensation that may persist
  5. Damage to deeper structures such as nerves, blood vessels, muscles, lungs and abdominal organs
  6. Deep vein thrombosis, cardiac and pulmonary complications
  7. Fluid accumulation
  8. Infection
  9. Irregular contours or asymmetries
  10. Irregular pigmentation
  11. Need for revision surgery
  12. Persistent swelling
  13. Poor wound healing
  14. Rippling or loose skin, worsening of cellulite
  15. Swelling
  16. Thermal burn or heat injury from ultrasound with the ultrasound-assisted lipoplasty technique

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

Abstract

Background: No concrete data exist to support a specific volume at which liposuction becomes unsafe; surgeons rely on their own estimates, professional organization advisories, or institutional or government-imposed restrictions. This study represents the first attempt to quantify the comprehensive risk associated with varying liposuction volumes and its interaction with body mass index.

Methods: Suction-assisted lipectomies were identified from the Tracking Operations and Outcomes for Plastic Surgeons database. Multivariate regression models incorporating the interaction between liposuction volume and body mass index were used to assess the influence of liposuction volume on complications and to develop a tool that returns a single adjusted odds ratio for any combination of body mass index and liposuction volume. Recursive partitioning was used to determine whether exceeding a threshold in liposuction volume per body mass index unit significantly increased complications.

Results: Sixty-nine of 4534 patients (1.5 percent) meeting inclusion criteria experienced a postoperative complication. Liposuction volume and body mass index were significant independent risk factors for complications. With progressively higher volumes, increasing body mass index reduced risk (OR, 0.99; 95 percent CI, 0.98 to 0.99; p = 0.007). Liposuction volumes in excess of 100 ml per unit of body mass index were an independent predictor of complications (OR, 4.58; 95 percent CI, 2.60 to 8.05; p < 0.001).

Conclusions: Liposuction by board-certified plastic surgeons is safe, with a low risk of life-threatening complications. Traditional liposuction volume thresholds do not accurately convey individualized risk. The authors’ risk assessment model demonstrates that volumes in excess of 100 ml per unit of body mass index confer an increased risk of complications.

SAFETY ISSUES AND COMPLICATIONS

However, with liposuction being performed by untrained professionals, in non-accredited office settings, and with continually increasing lipoaspirate volumes, reports of serious complications have surfaced, prompting scrutiny into procedural safety. [7] [8] [9] [10] [11]

The reported incidence of death after liposuction varies dramatically between 2.6 and 20.6 per 100,000. [12] [13] [14]

In an American Society for Aesthetic Plastic Surgery survey, thromboembolism, abdominal/viscus perforation, fat embolism, and cardiorespiratory failure were the most common discernible causes of death.

The majority of deaths had no identifiable cause, leading to speculation that unrecognized volume overload and lidocaine toxicity may be more significant precipitants of mortality than previously thought. [15] [16]

CONCLUSIONS

Liposuction performed by board-certified plastic surgeons is safe, with an exceedingly low risk of life-threatening complications. Traditional liposuction volume thresholds do not accurately convey individualized risk. By incorporating body mass index, we demonstrate that liposuction volumes in excess of 100 ml per unit of body mass index confer an increased risk of complications.
