Intrapleural fibrinolysis in acute non‐traumatic retained haemothorax

Haemothorax is an accumulation of blood in the pleural space. Retained haemothorax refers to blood that cannot be drained from the pleural cavity and is associated with an increased risk of empyema and fibrothorax often necessitating surgical evacuation. We describe our experience of using intrapleural fibrinolytic therapy in three patients with different bleeding risk and acute non‐traumatic retained haemothorax. The first was a 41‐year‐old female with disseminated Candida guilliermondii sepsis and an iatrogenic haemothorax, second was a 48‐year‐old female with transfusion‐dependent acute myeloid leukaemia and spontaneous haemothorax, and the third was a 72‐year‐old female with spontaneous haemothorax from newly diagnosed lung cancer. All patients received one to two doses of intrapleural alteplase without any bleeding complications and resolution of retained haemothorax. This case series demonstrates the successful application and safety of this approach as an alternative to surgery in a well‐resourced environment with close monitoring and ready access to blood transfusion.
