  1. 13 cases of intrapleural administration of alteplase for acute empyema , Nishina Mai; Yamaki Minoru; Noriyuki Toshio , The Journal of the Japanese Association for Chest Surgery , 39 , 6 , 527 , 532 , 15, Sep. 2025
    Summary:The number of surgeries for empyema is increasing in Japan, and treatment is often difficult. Although decortication is recommended, there are often cases where it is difficult to move quickly to surgery. Although fibrinolytic agents are not recommended in the guidelines, clinically, there are many reports of their use and effectiveness, and we have seen cases in which surgery was avoided with the use of urokinase. After that, it became difficult to obtain urokinase, and the number of patients undergoing surgery has increased, so we started using alteplase as an alternative drug. Of the 19 cases diagnosed with empyema, we used alteplase in 13 cases, among which surgery was avoided in 10 cases, but performed in 3 cases due to poor efficacy. The number of surgeries, which had been on the increase, clearly decreased. One patient died of pneumonia after empyema healed. Although there is some concern about the risk of bleeding with alteplase, only one case of intraoperative and postoperative bleeding was observed at our hospital. Intrathoracic administration of alteplase is considered to be useful in the treatment of empyema.

  3. Pneumothorax caused by migration into thoracic cavity of Kirschner steel wire used to fix a humerus fracture: A case report , Harada Hiroaki; Fujiwara Makoto; Nishina Mai; Shibata Satoshi , The Journal of the Japanese Association for Chest Surgery , 35 , 4 , 292 , 296 , 15, May. 2021
    Summary:An 80-year-old man was transported to our hospital because of a pneumothorax caused by migration into the thoracic cavity of Kirschner steel wire used to fix a humerus fracture. About a month previously, fixation of a fracture of the proximal portion of the humerus by Kirschner steel wire was performed under local anesthesia. Subcutaneous emphysema appeared 4 days after removing two of the steel wires used for fixing, and a radiograph revealed that one of the remaining steel wires had migrated into the thoracic cavity. CT showed the steel wire in the right middle lobe and slight pneumothorax with subcutaneous emphysema, although neither hemothorax nor bleeding in the lung parenchyma was observed. Emergency surgery was performed on the same day, and the steel wire was removed through a thoracoscopic approach. Although intrathoracic migration of Kirschner steel wire used for fixing fractures around the collarbone or shoulder joint is rare, it has the potential to be a fatal complication; here, we report a case along with a literature review.
