    • Intrathoracic Breast Transposition: A New Method in the Treatment of Bronchopleural Fistula and Empyema 

      de Weerd, Louis; Endresen, Petter Cappelen; Numan, Anmar; Weum, Sven (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      A bronchopleural fistula (BF) is a life-threatening complication. Optimal management of a BF is still debated although surgery remains the preferred treatment. Usually, the fistula is a result of inadequate healing at the bronchial stump after pneumonectomy. Successful closure of a BF after pneumonectomy depends on evacuation of empyema, coverage of the suture line after fistula closure with ...
