Pulmonary interstitial emphysema: selective bronchial occlusion with a Swan-Ganz catheter.

A 26 week preterm infant ventilated for hyaline membrane disease developed severe pulmonary interstitial emphysema with extensive right sided bullous formation, mediastinal shift, and subsequent left sided atelectasis. A paediatric Swan-Ganz catheter was used for selective bronchial occlusion with dramatic improvement in the infant's clinical condition and radiographic findings.
