| 説明 | Persistent interstitial pulmonary emphysema (PIPE) occurs mainly in preterm infants subjected to artificial ventilation for the respiratory distress syndrome. It caused by alveolar rupture resulting in dissection of air along bronchovascular bundles and interlobular septae; dissection of air may extend into the mediastinum and/or pericardium and may disrupt the visceral pleura resulting in pneumothorax. When present for more than a week the adjective "persistent" replaces "acute" Foreign body type giant cells overlie the loose connective tissue wall of this air cyst. The present of foreign body giant cells lining the cysts separates PIPE from acute interstitial emphysema. Thee giant cells are reacting to air. Other situations in which there are giant cells reacting to air include reactive eosinophilic pleuritis associated with pneumothorax, pneumatosis intestinalis and pneumatosis vaginalis. |
