[A case of spontaneous hemopneumothorax occurred after thoracocentesis]

A 41-year-old man was admitted to our hospital complaining of severe right chest pain and dyspnea. Soon after, right thoracocentesis was done and pleural free air was aspirated. Twenty minutes later he fell into a shock status. Chest roentgenogram showed massive right pleural fluid collection. Chest drainage revealed that massive bleeding continued. Therefore, emergent thoracotomy was performed. Bleeding point was a ruptured stump of pleural adhesion of the apical parietal pleura. His postoperative course was almost good, and discharged on the tenth postoperative day. Careful observation after thoracic aspiration is necessary in the treatment of spontaneous pneumothorax.
