Complications can occur after all surgery and liposuction is no exception. This is a list of some of the possible problems.
Contour or surface irregularities: these may be indentations or fine pitting like a cellulite pattern. Cellulite is not usually improved by traditional liposuction and may be made worse.
Pigmentation change: the skin above the area of fat removal may develop a brownish discoloration.
Loss of skin: extensive liposuction can damage the blood supply to the skin leading to loss of skin.
Bleeding: traditional liposuction can cause bleeding which may be severe. In some cases this may collect as a blood clot called a hematoma under the skin. This may require surgery to remove.
Seroma: especially when large volumes of fat are removed a space is formed between the skin and the underlying muscle. This may become filled with serum producing a seroma. Drainage may be required to correct this. It may be more common with ultrasonic liposuction.
Swelling or Edema: persistent swelling may occur especially in the lower leg and when suctioning extends circumferentially around the leg.
