: Re-expansion pulmonary edema is a rare and potentially life-threatening complication that can occur after the rapid re-expansion of a collapsed lung due to pneumothorax or pleural effusion. It has a multifactorial pathogenesis, and risk factors for re-expansion pulmonary edema, such as chronic lung collapse, rapid re-expansion, and changes in pulmonary vascular permeability, have been identified. Clinical manifestations vary, ranging from almost asymptomatic to a rapidly fatal condition, and its incidence may be more common and less fatal than previously believed. The literature emphasizes the importance of early recognition and management to ensure favorable outcomes. However, there is ongoing debate regarding the indications for ventilatory support and the timing of non-invasive or invasive ventilation. Herein, we report a case series of three paradigmatic examples of massive re-expansion pulmonary edema occurring over a period of 10 years in our institution among a population of 815 patients with spontaneous pneumothorax. We also conducted a literature review on re-expansion pulmonary edema, with a particular focus on diagnosis and management. In each case, despite initially normal clinical parameters, severe respiratory distress developed following the insertion of a thoracic drainage tube for a massive spontaneous pneumothorax. Two patients required High-Flow Nasal Oxygen, and one was addressed to intensive management, including CPAP. In all cases, the patient's outcome was optimal.

Abstract
: Re-expansion pulmonary edema is a rare and potentially life-threatening complication that can occur after the rapid re-expansion of a collapsed lung due to pneumothorax or pleural effusion. It has a multifactorial pathogenesis, and risk factors for re-expansion pulmonary edema, such as chronic lung collapse, rapid re-expansion, and changes in pulmonary vascular permeability, have been identified. Clinical manifestations vary, ranging from almost asymptomatic to a rapidly fatal condition, and its incidence may be more common and less fatal than previously believed. The literature emphasizes the importance of early recognition and management to ensure favorable outcomes. However, there is ongoing debate regarding the indications for ventilatory support and the timing of non-invasive or invasive ventilation. Herein, we report a case series of three paradigmatic examples of massive re-expansion pulmonary edema occurring over a period of 10 years in our institution among a population of 815 patients with spontaneous pneumothorax. We also conducted a literature review on re-expansion pulmonary edema, with a particular focus on diagnosis and management. In each case, despite initially normal clinical parameters, severe respiratory distress developed following the insertion of a thoracic drainage tube for a massive spontaneous pneumothorax. Two patients required High-Flow Nasal Oxygen, and one was addressed to intensive management, including CPAP. In all cases, the patient's outcome was optimal.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
