Häufigkeit abnormer Ultraschallbefunde an der Lunge von 129 Kälbern mit Bronchopneumonie

Abstract

The goal of this study was to analyse the frequency of ultrasonographic findings in 129 calves with bronchopneumonia and to determine how often multiple abnormalities occur in individual calves. The frequency of abnormal ultrasonographic findings ranged from 4 to 88%. Comet-tail artifacts were the most common finding (88%) followed in decreasing order by scattered echogenic foci (69%), air bronchograms (44%), superficial alveolograms (29%), pleural effusion (26%), hepatisation (23%), pleural lesions (18%), fluid bronchograms (14%), lung abscesses (6%) and fibrin deposits or fibrin strands (4%). Thoracic ultrasonography yielded a mean of 3.3 ± 1.55 abnormal findings (range, 1-6) per calf. Ultrasonography of the lungs in calves with bronchopneumonia is a useful adjunct to clinical examination and allows the determination of the type and severity of lesions.
