[Vacuum-assisted Closure Therapy for Residual Space after Open Window Thoracotomy for Pleural Empyema due to Bronchopleural Fistula].

A 73-year-old man underwent right middle-lower bilobectomy for lung adenocarcinoma. He suffered from pneumonia followed by empyema due to bronchopleural fistula. On day 19 after the operation, an open window thoracostomy was created. Then the pleural space was treated conservatively with saline irrigation and petrolatum gauze packing. Progressive formation of healthy granulation tissue was observed around the bronchopleural fistula and the adjacent pulmonary artery, resulting in a complete closure of the bronchopleural fistula. And then we applied vacuum-assisted closure (VAC) therapy to the residual pleural cavity. At 4 weeks after the initiation of VAC therapy, the pleural cavity was completely filled with granulation tissue and re-expanded residual lung. In conclusion, VAC therapy is a safe and effective treatment for residual space after open window thoracostomy for empyema due to bronchopleural fistula, if it is applied after closure of bronchopleural fistula and adequate granulation tissue formation on the great vessels.
