Fat Embolism After Autologous Facial Fat Grafting
Abstract Background Autologous facial fat grafting has gained popularity in recent years and is considered to be safe. We present the case of a patient who died due to massive cerebral micro fat embolism after facial fat grafting. Objectives Raising awareness and providing more evidence on prevention and treatment of this potentially lethal complication of facial fat grafting. Methods A detailed report was made of the case. Two online databases were searched for similar cases of facial fat embolism resulting in neurological and/or visual symptoms. Thereafter a literature search was conducted to verify the etiology, current treatment options, and preventive measures. Results Forty-nine cases with similar events were found in the literature. The most common injected area was the glabella (36.1%), and an average of 16.7 ml fat was injected. The main complications are visual impairment, of which 88.5 % remained blind, and neurological symptoms, who never fully recover. Seven cases were fatal. Fat embolism can occur in veins and arteries of the face. Two possible pathways for fat embolism exist: the macroscopic, mechanical pathway with immediate signs and the microscopic, biochemical pathway with delayed symptoms. Mechanical embolectomy and corticosteroids are suggested treatment options but lack evidence. Several different preventive measures are described. Conclusions Although facial fat grafting is considered a safe procedure, one should be aware of the risk for fat embolism. Underreporting of this adverse event is likely. With no effective treatment and often detrimental outcome, preventive measures are of utmost importance to improve patient safety.
