1/6. prenatal diagnosis and management of congenital lobar emphysema.

    BACKGROUND: Congenital lobar emphysema (CLE) is a rare anomaly of lung development that usually presents in the neonatal period with respiratory distress and pulmonary lobar hyperinflation. The routine use of prenatal ultrasonography has resulted in the early identification and serial evaluation of congenital lung lesions. CLE can be distinguished from other congenital lung lesions on ultrasonography by the differences in echogenicity and reflectivity. methods: Two cases of CLE diagnosed at midgestation by ultrasonography and ultrafast fetal magnetic resonance imaging (MRI), along with serial sonographic documentation of their prenatal course were reviewed. RESULTS: The CLE lesions decreased in size over the course of the pregnancy, similar to that seen with other congenital lung lesions such as cystic adenomatoid malformation and bronchopulmonary sequestration. However, these neonates with CLE showed marked air-trapping and respiratory distress requiring lobectomy in the early neonatal period. CONCLUSIONS: These cases provide insight into the prenatal course of CLE and underscore the need for continued postnatal evaluation of fetuses even those in whom the lesions appear to have resolved in utero. These patients should have ready access to postnatal surgical intervention.

2/6. lung volume reduction surgery in bronchopulmonary dysplasia.

    We report on a female preterm infant of 29 wk gestational age, who developed acquired lobar emphysema after prolonged artificial ventilation secondary to respiratory disease syndrome and bronchopulmonary dysplasia. The infant underwent atypical segmentectomy at the age of 12 mo because of life-threatening hypoxaemia with pulmonary hypertension and failure of conservative treatment. Conclusion: lung volume reduction surgery (LVRS) dramatically improved the respiratory function and resulted in adequate weight gain and psychomotor development. In selected cases LVRS can be an option for lobar emphysema in premature infants with severe bronchopulmonary dysplasia.

3/6. Partial bronchial stenosis following inadvertent right bronchial intubation in a neonate.

    This case reports difficulties encountered in weaning a premature infant with bronchopulmonary dysplasia from prolonged mechanical ventilation. On chest X-ray alternating atelectasis and hyperinflation of the right lung were observed. This resulted from a short episode of misplaced endotracheal tube that produced a traumatic bronchial stenosis. Treatment by prednisolone allowed the detubation.

4/6. Congenital intrathoracic bronchopulmonary foregut malformations in childhood.

    Bronchopulmonary foregut malformations (BPFM) are a group of related disorders. They include tracheoesophageal fistula with or without atresia, bronchopulmonary sequestration, intestinal duplication cyst, bronchogenic cyst, aberrant systemic arterial supply to the lung, and bronchial mucosal rests in the esophagus. This paper describes 12 cases which illustrate the spectrum of clinical and radiographic features of these anomalies. The embryogenesis of these malformations is reviewed and appropriate radiographic investigation is discussed.

5/6. Progressive interstitial pulmonary lobar emphysema.

    Progressive pulmonary interstitial lobar emphysema is a complication of artificial ventilation in premature infants with RDS. Three cases are presented who developed a progressive form of PIPE. It is demonstrated that PIPE is caused by air escaping through alveolar leaks into the pulmonary lymphatic capillary system causing dilation of lymphatic channels. Because of its increasing compressive effect on adjacent lung areas PIPE requires rapid and effective therapy. Although several types of conservative approach are suggested, lobectomy is not indicated when prolonged ventilation with high pressures and high concentrations of oxygen have caused severe bronchopulmonary dysplasia.

6/6. Acquired lobar emphysema in premature infants with bronchopulmonary dysplasia: an iatrogenic disease?

    Five premature infants in whom bronchopulmonary dysplasia developed following prolonged neonatal respiratory support are presented. In all five patients, right middle and/or lower lobe emphysema related to focal obstructing endobronchial masses of granulation tissue subsequently developed. It is speculated that the granulation tissue formed in response to the repeated mechanical trauma of endotracheal tube suctioning.
