| Abstract |
Purpose
: Early diagnosis of foreign body aspiration and removal of the inhaled material may
save the patient from chronic illness and may prevent serious complications. At present the
diagnostic problems of bronchial foreign bodies are being solved by using the lung scanning
technique. Therefore, we investigated the clinical study and diagnositic value of the lung perfusion
scan in foreign body aspiration.
Methods
: Eighteen cases of airway obstruction due to foreign bodies were treated in the
department of pediatrics, Kyung Hee University Hospital. We retrospectively, reviewed patient
records to determine the clinical findings, radiologic findings, and findings of the perfusion lung
scan.
Results
: Fifteen cases(83.2%) out of 18 were less than 2 years of age, and the male to female
ratio was 1.3:1. Vegetables, especially peanuts were the most common aspirated foreign bodies,
and accounted for 72.2% of the cases. Of all foreign body obstructions, 61% were lodged in the
main bronchi and there was no significant difference between the right and left main bronchus. In
radiologic findings, obstructive emphysema(50%) was most common, followed by atelectasis(33%),
mediastinal shifting(23.3%) and pneumonia(22.2%), respectively. There were more severe defects
and a higher incidence of abnormalities in cases with prolonged periods after inhalation than that
of shorter duration cases.
Conclusion
: Lung perfusion scanning is useful in the diagnosis of foreign body aspiration which
presents a vague history of aspiration, insufficient clinical manifestation and normal chest
radiologic findings. Our results show that perfusion scan can be helpful particularly in cases of
long duration foreign body obstruction. |
