[A case of pulmonary fat embolism and cardiac arrest after prosthetic replacement of the femoral stem].

We experienced a case of cardiac arrest which occurred after prosthetic replacement of the femoral stem. The patient died three hours and fifty minutes after the end of operation, following hypouresis, pulmonary edema and hypoxia. According to the autopsy, extensive and severe fat embolism was documented in the lung and kidney, and this is considered to be the cause of the death. When prosthetic replacement of the femoral head is performed, we have to keep in mind the danger of fat embolism.
