Is That Innocent to Touch the Adipose Tissue?: An Autopsy Case Series of Fat Embolism Syndrome.

Abstract

Although fat embolism in the pulmonary or systemic circulation is usually associated with long bone fractures, it can also occur less frequently during surgical operations, such as liposuction, fat grafting, and joint repair. This study aims to present cases of macro fat embolism resulting in sudden death during the perioperative period. Three cases with a history of sudden death during the perioperative period were included in this study. The surgical operation histories, autopsy findings, and histopathological findings of the cases were evaluated. Fat globules were detected in the medium-sized vessel lumens in the lungs of the cases who died suddenly during surgery. Grade 4 fat embolism was observed in the capillaries, which stained positively with Oil-Red-O in all three cases. Fat embolism syndrome is a rare but life-threatening condition that should be considered in patients with respiratory distress and impaired neurological status in the postoperative period.
