Effectiveness of Decompressive Hemicraniectomy to Treat a Life-Threatening Cerebral Fat Embolism

Abstract EN

Background and Importance.

Cerebral fat embolism (CFE) occurs mainly after long-bone fractures.

Often reducing to minor neurological disorders as confusion, it can sometimes cause more severe consequences such as coma or even death.

While CFE has been described for several years, there is no consensual treatment.

Clinical Presentation.

We report the case of a 15-year-old girl with a severe cerebral fat embolism secondary to a longboard fall with a femur fracture.

She developed in less than 4 hours a coma.

On day 4, she lost her brainstem reflexes with a clinical condition close to brain death, with a very high intracranial pressure (ICP) value above 75 mmgH at worst.

She was treated as having a trauma brain injury based on ICP control with a decompressive hemicraniectomy.

She recovered in some weeks, allowing discharge to a post ICU rehabilitation center, one month after admission.

Conclusion.

We report a severe case of cerebral fat embolism with good outcome.

It was managed as a trauma brain injury.

We emphasize the neurological management based on ICP and discuss the position of hemicraniectomy.
