Abstract
We report the case of a 72-year-old man with a soft tissue mass that was located in the right mediastinum and compressed the tracheal lumen externally, causing airway obstruction. He presented with severe dyspnea and disturbed consciousness. Tracheal stent implantation was performed for relieving the obstructed airway. After the procedure, his breathing was assisted with a T-piece. A few minutes later, he developed oxygen desaturation, productive cough with pink foamy sputum, and bilateral basal crepitations. Therefore, acute pulmonary edema was suspected. Type Ⅱ postobstructive pulmonary edema was diagnosed after the other types of pulmonary edema were ruled out. Awareness of the cause and mechanism of type Ⅱ postobstructive pulmonary edema could facilitate timely and appropriate postoperative care such as progressively weaning the patient from mechanical ventilator by decreasing positive end-expiratory pressure gradually.
