Cerebral Fat Embolism as Complication of Facial Fat Graft: Retrospective Analysis of Clinical Characteristics, Treatment, and Prognosis.

Background: Cerebral fat embolism (CFE) is a rare complication that usually occurs after trauma injury. The incidence of CFE due to aesthetic surgery is extremely rare and can lead to fatal outcome. Due to the rarity of this complication, there is still lack of knowledge and standardization of the treatment.

Case Description: Herein, we reported 6 cases of CFE that occurred in patients who underwent cosmetic surgery. Among 5 patients who had large artery occlusion, 3 patients survived and 2 patients died due to progression of the disease. One patient had the ophthalmic artery occlusion. In addition, embolectomy was performed in 5 patients and 3 patients had decompressive craniectomy following endovascular treatment due to severe brain edema.

Conclusions: CFE is associated with high morbidity and mortality, and early surgical intervention can improve the prognosis.
