Imaging analysis of pulmonary air leak in neonates / 实用放射学杂志

ABSTRACT

Objective To discuss the X-ray and CT findings of pulmonary air leak in neonates and to improve the early diagnostic ability.Methods The supine anteroposterior chest films of 33 neonates with pulmonary air leak were retrospectively analyzed.A-mong them,spiral CT scanning was performed in 5 cases.Radiographic follow-up was made in 30 cases.Results Pulmonary intersti-tial emphysema was found in 2 cases,pneumomediastinum in 4 cases,simple pneumothorax in 14 cases.Pulmonary interstitial em-physema combined with pneumomediasfinum was detected in 2 cases,with pneumothorax in 4 cases.Pneumomediastinum combined with pneumothorax was displayed in 3 cases.Pulmonary interstitial emphysema combined with pneumomediastinum and pneumotho-rax was found in 4 cases.Among them,medial pneumothorax was shown in 26 side,lateral pneumothorax in 9 side.Conclusion X-ray radiography is the main method for the diagnosis of pulmonary air leak in neonates,and CT can further define the location,range and extent of the disease.
