Liposuction Gone Awry
A 54-year-old man with HIV was referred to a
plastic surgeon for cosmetic surgery. In the plastic
surgeon’s office, he underwent neck and facial liposuction
with eyelid tightening under local anesthesia. There were no
complications at the time of the procedure and the patient was sent
After arriving home, the patient noticed an
expanding neck mass near the incision site and progressive
shortness of breath. He contacted the plastic surgeon, who directed
him to the nearest emergency department. Upon arrival, the patient
was in severe respiratory distress and needed an emergent
tracheostomy, secondary to neck swelling and edema. He was taken to
the operating room, where he was found to have a laceration of the
external jugular vein. The vessel was repaired and the patient
required a prolonged stay in the intensive care unit. He eventually
was discharged to home.
Location, location, location—this is the
mantra of the real estate market. But is location a factor in the
occurrence of the complication reported in the aforementioned case?
Is patient safety better assured if surgery is performed in a
hospital outpatient facility versus an ambulatory or office
surgical facility setting? This question has generated considerable
controversy, with proponents on both sides of the argument. The
case presentation lacks many details and leaves several unanswered
questions. Although the temptation is to see only operator-related
complications, several additional causative factors may have been
at play in this case:
Facility accreditation. Was the
facility accredited by any of the three nationally known
accrediting organizations: American Association for Accreditation
of Ambulatory Surgical Facilities (AAAASF), Joint Commission on
Accreditation of Healthcare Organizations (JCAHO), or Accreditation
Association for Ambulatory Health Care (AAAHC)? Was there state
licensure or Medicare certification? Such accreditation generally
ensures that the facility has all the equipment, staff, and
medications needed to manage on-site adverse events and
Patient status. What was the
patient’s American Society of Anesthesiologists (ASA) status?
In addition to his known HIV, could other comorbid conditions have
made him a poor candidate for an office surgical procedure? A
recent study (1)
found that men have a two times greater risk of hematoma than women
in cosmetic procedures, possibly due to higher rates of
Surgical site marking. Did the
surgeon mark the skin externally to identify the location of the
external jugular vein prior to injecting the site? Safe and sound
practice requires such identification of all potential high-risk
areas, such as blood vessels, nerves, or areas of unstable skin due
to radiation or other prior trauma.
Techniques used. What liposuction
techniques were employed (dry, wet, superwet, tumescent,
Currently, all of the “wet” methods appear to provide
much easier “passes” of the cannulae for the operating
surgeon; when lidocaine is used as part of the wetting solution, it
also seems to reduce post-operative pain. Additionally, bleeding
and post-operative bruising are far better controlled when
epinephrine is part of the solution being instilled.
Cannulae. What size cannulae were
used? Were they sharp or blunt? The sharp and larger
diameter–tipped cannulae have, for the most part, faded out
of use primarily because of the risks of nerve, vessel, skin, and
Post-operative wound management.
Were pressure dressings or ice packs applied to the treated areas?
Using these modalities as part of the post-operative wound
management has been shown to be moderately effective in controlling
swelling, edema, and, to some degree, hematomas.(3,4) These possible benefits and their minimal expense
should prompt their general use.
Post-operative observation. In
this case, given the type of vessel lacerated and its size, it is
surprising that marked swelling was not immediately observed prior
to the patient’s discharge. Was there a planned and
implemented period of post-operative observation for possible
immediate complications? The period for evaluation prior to
discharge on any patient should be based on a validated scoring
system. The most widely used is the Aldrete method, which estimates
the adequacy of recovery based on the patient’s level of
consciousness, activity, respiration, circulation, and color
(similar to an Apgar score).(5)
Patients should only be considered for discharge when all the
parameters in this 10-point scale have been achieved. The method is
not entirely prescriptive, however, since it does not define the
time frame to meet the discharge parameters, and so the recovery
time could be very short (eg, 30 minutes) to as long as several
hours. Much is also dependent on procedure performed, ASA levels,
and age of patient.
Post-operative instructions. Were
written post-operative instructions given to alert the patient of
any possible complications that could necessitate immediate
One must be careful not to use any of the above
as an indictment of office surgery procedures, since similar cases
have occurred in other settings. For example, I know a case in
which a patient died after an uncomplicated facelift performed
under general anesthesia. The patient strangled from a hematoma
under her dressing. This case took place in a community
hospital’s outpatient department, not an ambulatory
That said, office-based facilities have been the
site of many reports of serious complications and deaths. These
reports have received tremendous media attention, especially in
Florida. Between 2000 and 2002, Florida reported a ten-fold
increase in adverse events in procedures done in office-based
facilities versus freestanding ambulatory surgery
However, when these cases were reevaluated with more rigorous
techniques, the concerns were unfounded, with fewer than 1 adverse
event in 10,000 cases.(6) In
January 2002, a multi-disciplinary meeting convened by the National
Institutes of Health also found a low degree of adverse events in
office-based surgical procedures. These results mirrored similar
studies (involving voluntary reporting) by the AAAASF (7),
which found that the safety in accredited office-based surgery
facilities was equivalent to that in hospital outpatient
In 1999, the American Society of Plastic Surgeons
(ASPS) and the American Society of Aesthetic Plastic Surgery
(ASAPS) mandated that to maintain membership in either society one
must perform outpatient procedures only in an accredited facility
(by JCAHO, AAAHC, or AAAASF) or in a state-licensed unit.
Accreditation tells the potential patient that a certain standard
of patient safety has been achieved and evaluated and assures the
facility’s staff that they are working in a safe
Despite the above data, adverse events in
office-based facilities continue to be intensely reported by the
media. In view of this, the ASPS convened a task force on patient
safety in office-based facilities. One of its first advisories
concerned liposuction (8) and
incorporated many of the above concerns regarding cannula type,
safe amounts of wetting solutions, amounts of fat extracted, and
fluid replacement requirements.
This task force is developing additional
guidelines, partly trying to fill an information void, since there
are presently no reporting systems for office-based surgeries. One
recent study used an internet and peer review reporting system to
analyze 400,000 cases (since the report, the database has grown to
more than 800,000 cases) performed in roughly 1200 accredited
AAAASF facilities.(9) Of
the 2,597 reported unanticipated sequelae, hematoma was the most
common problem, reported in 0.18% of cases. Such hematomas
represented nearly one-third of reported sequelae. Other lesser
complications included infection, with an incidence of 0.09% of
performed procedures. Cardiac irregularities and sequelae accounted
for 0.007%. Less frequent complications were blood pressure
alterations, deep venous thrombosis, and pulmonary embolism (each
approximately 0.01%). A related study (10) of liposuction of the neck and jowls also found an
extremely low risk of voluntarily reported complications.
It is estimated that 10 million procedures were
performed in office-based facilities in the US in 2005 (11), a
remarkable volume. Patients appear to value the convenience,
privacy, staff consistency, and efficiency of such facilities.
Nevertheless, the fact that only 1200 of 40,000 office-based
facilities in the United States are currently accredited by the
AAAASF is a concern (12);
it should be noted that some other office-based practices are
accredited through JCAHO (13)
and AAAHC. All these organizations have fairly similar bases for
evaluation of the facilities (Table) (14),
scrutinizing all areas of the facilities carefully for possible
Overall, our organization believes that the
accreditation process is needed to ensure that office-based
practices are as safe as hospital-based practices. Present evidence
clearly demonstrates that the accredited office facility, staffed
by appropriately trained and credentialed providers, is as safe as
any other environment for care today.(16) To date, there have been no studies to the contrary.
Additionally, for surgeries in office-based facilities, the length
of the surgical procedures has no bearing on the frequency of safe
- If performed in an accredited facility,
office-based surgery is as safe as hospital-based surgery.
- All office-based surgical facilities
should be accredited by AAAASF, JCAHO, AAAHC, or the

employed in outpatient plastic surgery to reduce the risk of
- Validated scoring systems should be used
to assess adequacy of recovery from surgery prior to discharge
post-operatively in office-based procedures.
