Risk of Pulmonary Embolism During Fat Transfer?

There are risks with every procedure and the removal of fat for fat injections does carry with it some risks, but the risk of a pulmonary embolus related to the procedure is very low if it is a small procedure and peformed as a sole treatment. Risks increase when multiple procedures are done together and there is a lot of fat removal, which is not the case normally with fat injections.

With large volume fat transfers in areas with large vessels such as the buttocks, there is a risk of pulmonary fat embolism. In the face, there has never been a report of a PE with fat transfer and it although I never say never, I would say the risk is extremely small and not quantifiable.

There are 2 types of embolism that you may be thinking about.

Pulmonary embolism (PE) is a blood clot that typically forms in the legs and can travel to your lungs where it may cause serious problems including death. This is a risk with almost any major surgical procedure. The risk of PE depends on the length of surgery, your age, your overall health and many other risk factors (Google: Caprini risk factors). If the fat grafting procedure involves only small volumes of fat and is done using a local anesthetic, then the risk for PE is almost zero.

Fat embolism (FE) if much less common and has been seen after significant bone fractures, liposuction, and rarely after fat grafting. We don't have enough information to know all the risk factors and overall statistics. However, based on available information, the risk is very low (less than 1 in 1000) but at least one death that followed facial fat grafts was linked to fat embolism.

Every surgical procedure carries some risk of complication. The risk of DVT and possibly a pulmonary embolus related to the deep venous thrombosis after fat grafting are quite low (but not zero). These is a phenomenon called "Fat Embolus" which can occur with injection of fat. If fat is injected into a vein, it can travel to the central circulation of the heart and lungs- possibly causing a fatal problem. That said, the risk of fat embolus, in the hands on qualified plastic surgeons should also be quite low.

I suggest that you look at the "Fat Transfer/Fat Graft and Fat Injection ASPS Guiding Principles" published by the American Society of Plastic Surgeons (and available on its web site) for more information.

All surgeries has a risk of deep venous thrombosis and pulmonary embolism. the risk is dependant on the amount of liposuction to be dine. avarage risk for large liposuction is about 1.7%. The actual transfer of fat when done with blunt canula is very rare
