Report on Mortality from Gluteal Fat Grafting: Recommendations from the ASERF Task Force.

Background: Gluteal fat grafting is among the fastest growing aesthetic procedures in the United States and around the world. Given numerous anecdotal and published reports of fatal and nonfatal pulmonary fat embolism resulting from this procedure, the Aesthetic Surgery Education and Research Foundation (ASERF) formed a Task Force to study this complication.

Objectives: To determine the incidence of fatal and nonfatal pulmonary fat embolism associated with gluteal fat grafting and provide recommendations to decrease the risks of the procedure.

Fat transfer and fatal macroembolization.

Fat embolism is usually associated with long bone fractures or other trauma. The diagnosis is usually clinical, and in most cases, emboli are not fatal and not usually seen on gross examination. At the Los Angeles County Coroner's Office, we autopsied the victim of fatal macroscopic fat embolization to the lungs.
