When Does Fluid Build-up After Liposuction Begin to Subside?

I have seen only one seroma after liposuction and it was in a very large gentleman with 4 Liter fat removal from the abdomen. The amount of "dead space" left after the removal of the fat contributed to the development of the seroma I am sure. This resolved with conservative therapy (time, pressure garment, decreased activity). This was very small and didn't even require drainage. It sounds as if yours is large enough to have required drainage. This may need to be drained a few more times and possibly would even benefit from a sclerosant injected into the cavity after aspiration. Seromas are frustrating but they tend to improve once the balance of fluid removal by lymphatics is as quick as fluid creation by your healing tissues.

It seems as if certain modalities have a higher propensity to develop seromas or fluid buildup. For example, it is more common after ultrasonic liposuction. Did you have this?
It also is more common after aggressive liposuction where an extensive cavity with raw surfaces are left.
Typically, they resolve over time. It is difficult to predict how much time but commonly you will see a drop off in the amount that is drawn off. However it may take a few weeks or even a few months.
There is not consistent method to treat other than ongoing aspirations. Other methods have been used with mixed success such as opening and closing the cavity, drain placement, instillation of a sclerosing agent quitling sutures, etc.
As you have been advised, avoid tight garments that gather and create a tourniquet effect.

Hi there,
I agree with the other surgeons that this is a problem very rarely seen. I have never had this happen in a very large number of arm cases. The important points are to maintain a constant and firm compression of the area, in conjunction with your surgeon's drainage procedures. I have also had success with use of percutaneously placed indwelling drains (drain tubes your doctor can put in in the office). The problem should take care of itself over time and your outcome should still be favorable.
