A rare fatal cerebral fat emboli syndrome with large vessel occlusion post femur fracture plating in an older female: A case report

Introduction and importance: Cerebral fat embolism syndrome is a rare complication of long bone fractures, often overlooked and found in late stages. We present patient with a late recognition of Cerebral Fat Embolism with Large vessel occlusion post femoral internal fixation. Case presentation: An elderly female suffered right intertrochanteric fracture after falling down. Open reduction internal fixation with Interlocking plate was performed at the fifth day. Upon returning to the ward, the patient did not regain full consciousness and apparent right hemiparesis were observed. A head Computed Tomography was performed and found left hemisphere ischemia consistent with middle cerebral artery occlusion. The patient condition worsened and died 3 days postoperatively. Clinical discussion: Cases of fat embolism that occur purely isolated in the brain are rare cases that occur after internal fixation of the femur, so they are often not noticed by clinicians. Several factors can increase the risk of the event, delay in fixation and diabetes mellitus which was found in our patient could increase the risk of fat emboli syndrome. Apart from that, osteoporosis also increases the risk of fat embolism syndrome that was found in our subject. Conclusions: Cerebral Large Vessel Occlusion Fat Embolism Syndrome is rare case occur following internal fixation. There is a need for early recognition to be carried out to treat early or prevent the occurrence of fat embolism.
