Abstract:
Persistent interstitial pulmonary emphysema is a rare condition that occurs in preterm infants on mechanical ventilation, characterized by abnormal accumulation of air in the pulmonary interstitium, due to disruption of the basement membrane. Diffuse persistent interstitial pulmonary emphysema is observed when small cysts are noted in all lobes of the lung. The management of infants suffering from diffuse persistent interstitial pulmonary emphysema varies according to severity and stability of the patient, being either conservative treatment or aggressive surgical treatment by pneumonectomy. We report a case of an unstable patient with diffuse persistent interstitial pulmonary emphysema successfully treated by lobectomy as a form of conservative surgical approach.
