Abstract

BACKGROUND: Fat Embolism Syndrome (FES) is a rare condition where circulating fat emboli can lead to life threatening multisystem dysfunction. Diagnosis of FES occurs mainly by exclusion. The aim of this study was to describe the injury, event details, and factors associated with the diagnosis of FES following trauma presenting to a Level 1 Trauma Centre in Melbourne, Australia.

METHODS: Medical records of all patients with a complication of FES between 2006 and 2018 were retrospectively reviewed. Demographics, injury factors, hospital event details, radiological procedures and length of stay were collected.

RESULTS: Thirty six patients, with median age of 26 years (IQR 19, 42) and median Injury Severity Score (ISS) of 18.5 (IQR 10, 27) were diagnosed with FES. Other associated factors included male gender (86%) and having one or more long bone fractures (97%). Of the major FES diagnostic criteria, 94% of patients experienced hypoxia, 36% had mental status changes, whereas only 11% had petechiae. Computed Tomography Pulmonary Angiogram (CTPA) was performed on 19 patients (53%) with all being negative for pulmonary embolus. Most demonstrated ground glass opacity (58%), and FES was reported as the likely cause of patient presentation in 53% of cases.

CONCLUSION: FES following trauma was rare, with its diagnosis based on clinical factors including long bone fracture and hypoxia, and the exclusion of other respiratory diagnoses. CTPA was frequently used since 2008 and further research is warranted to determine if this radiological procedure can assist with more definitive diagnosis of FES.
