[Prolonged coma due to fat embolism syndrome after fracture of the femur].
A 24-year-old male came to the emergency department with a diaphyseal fracture of the femur resulting from a motorcycle accident. Neurological deterioration was progressive, although a computed tomography scan was normal. Endotracheal intubation for mechanical ventilation was necessary. His condition progressed to sepsis and multiorgan failure before resolving. Magnetic resonance images of the brain suggested a fat embolism. The presence of a patent foramen ovale was investigated. The patient remained in a state of coma vigil for 3 months after the accident. After ruling out other more likely causes of neurological deterioration after trauma with fractures, fat embolism should be suspected. The prognosis for the neurological manifestations of fat embolism syndrome are generally good. Severe cases suggest massive (paradoxical) embolization of the brain and are associated with a patent foramen ovale. Early diagnosis will identify the patient at high surgical risk. A favorable course and outcome have been reported with preoperative closure of the foramen ovale.
