Liposuction is a relatively low risk procedure from either a fat embolism or a blood clot. The relative risk of a blood clot in the leg and/or lung is about 0.8 percent for liposuction (vs. 1.2% risk with tummy tuck). Three are many things you can do to minimize this risk, including scoring your prior medical and family history for risk factors and scoring, using SCD'd (Calf Squeezers) and/or Lovenox (Blood Thinners) to decrease the risks. Regarding fat embolism, I use the VASER which is an advanced liposuction device, that minimizes connective tissue and blood vessels damage, thus reducing the risk of a fat embolism. to my knowledge there have been no fat embolisms reported with the use of the VASER in its over 14 years of use and millions of cases performed.
