Abstract

Objectives: Foreign body aspiration (FBA) has a wide clinical spectrum, patients may be asymptomatic or present with cardiopulmonary arrest. Radiological imaging methods are used in addition to history and physical examination findings for certain diagnosis. Lung ultrasonography (LUS), whose usage area is increasing year by year, can be included in these. This study aimed to investigate ultrasonography findings in FBA and hypothesized that LUS may have a standard place in FBA diagnosis.

Methods: Patients who administered to the pediatric emergency department between August 2019-August 2021, considered according to the clinical findings and physical examination possible FBA, and who undergone rigid bronchoscopy by pediatric surgery were included in the study.

Results: Thirty-two patients were included in the study. According to the results of bronchoscopy, FBA was detected in 25 patients. The most common finding in radiography was hyperinflation on one side, while LUS findings were confluent-B lines in eight patients, barcode-sign in five patients, pleural line abnormalities in two patients, and pleural consolidation in two patients.

Conclusion: This study is the first study aiming to evaluate LUS findings in FBA to the best of our knowledge. The B-lines, barcode sign, pleural line abnormalities and consolidation are seen findings in LUS of the patients with FBA. Although it is far from replacing chest radiography in these patients, it is possible to say that it has an equivalent value with chest radiography.
