ABSTRACT
BACKGROUND:
Tracheobronchial foreign body (TFB) aspiration is a significant cause of respiratory problems in children. The timely diagnosis of TFB is important to decrease the mortality rate and the incidence of complications. Advances in radiology have led multi-slice spiral computed tomography (MSCT) to become the best technique for diagnosing TFB.METHODS:
We performed a retrospective study over 5 years from July 2008 to June 2013. We collected information on children who were diagnosed with a TFB by bronchoscopy, and analyzed age, sex, location, type of foreign body, and various MSCT manifestations.RESULTS:
A total of 382 children were included and 68.6% of them were aged 1 to <2 years. The majority (95.8%) of aspirated foreign bodies were vegetation items, and nearly half (47.6%) of them were peanut kernels, followed by sunflower seeds (26.2%). A total of 4.7% of TFBs were in the trachea, 51.0% were in the left main bronchus, and 44.2% were in the right main bronchus. Among the TFBs, 359 (95.5%) showed a high-density shadow in the tracheal / bronchial lumen using MSCT, which could establish the presence of a foreign body directly. Emphysema, localized obstruction and pneumonia were more commonly detected in the 7-21 days and ≥21 days group compared with those in the <7 days group (all P < 0.01). Bronchiectasis was found in two children who were diagnosed at least 21 days after aspiration.CONCLUSIONS:
Multi-slice spiral computed tomography is very sensitive to TFBs. Timely diagnosis and treatment of TFB is important to prevent long-term sequelae in children.Palavras-chave
