Abstract:

BACKGROUND: For the etiology, pathogenesis, clinical manifestations, diagnosis, treatment and prevention of fat embolism after arthroplasty, scholars have put forward various theories and performed a large number of experiments. However, there is still no criteria and guidance about its diagnosis and treatment.

OBJECTIVE: To review the diagnosis and treatment of fat embolism, thus providing clues for the studies on fat embolism.
METHODS:PubMed database was retrieved for the literature published from 2010 to 2017 with the keywords of “fat embolism, fat embolism syndrome, total hip arthroplasty, total knee arthroplasty, joint replacement”. Finally, 38 eligible articles were included for retrospective analysis.
RESULTS AND CONCLUSION: (1) Lipid droplet formation is caused by a variety of factors, and when it appears in circulatory system, fat embolism syndrome occurs. The pathogenesis still remains unclear; and mechanical theory and chemical theories are acceptable. The manifestations of fat embolism syndrome are non-specific, from asymptomatic to sudden death, which makes its diagnosis difficult and there are no unified diagnostic criteria. (2) Physical examinations such as X-ray, CT, ultrasound, and MRI have their own merits. Until now the treatments are mainly anti-inflammatory, anticoagulant, thrombolysis cardiotonic and other supportive treatments. (3) Given this, prevention is critical, and intramedullary depressurization, intramedullary canal irrigation and glucocorticoid may be the newest direction.
