title: An unusual case of foreign body pulmonary embolus: case report and review of penetrating trauma at a pediatric trauma center.
abstract: OBJECTIVE
  Penetrating thoracic trauma is relatively rare in the pediatric population. Embolization of foreign bodies from penetrating trauma is very uncommon. We present a case of a 6-year-old boy with a penetrating foreign body from a projectile dislodged from a lawn mower. Imaging demonstrated a foreign body that embolized to the left pulmonary artery, which was successfully treated non-operatively.
  
  
  METHODS
  We reviewed the penetrating thoracic trauma patients in the trauma registry at our institution between 1/1/03 and 12/31/12. Data collected included demographic data, procedures performed, complications and outcome.
  
  
  RESULTS
  Sixty-five patients were identified with a diagnosis of penetrating thoracic trauma. Fourteen of the patients had low velocity penetrating trauma and 51 had high velocity injuries. Patients with high velocity injuries were more likely to be older and less likely to be Caucasian. There were no statistically significant differences between patients with low vs. high velocity injuries regarding severity scores or length of stay. There were no statistically significant differences in procedures required between patients with low and high velocity injuries.
  
  
  CONCLUSIONS
  Penetrating thoracic trauma is rare in children. The case presented here represents the only report of cardiac foreign body embolus we could identify in a pediatric patient.
