Liposuction to Inner and Outer Thighs, Knees, or Ankles - Is liposuction considered a major surgery?

Liposuction is not as serious as heart surgery but the same basic risks are present, such as formation of blood clots in the legs while lying on the operating room table or risks associated with infection or anesthesia. Additionally, liposuction, in rare instances, can cause particles of fat to enter the blood stream and travel to the lungs which can lead to shortness of breath but this is exceedingly rare.
