Multiple organ trauma are currently among the most frequent causes of death and massive chest injuries have very high mortality rate. The paper presents the model of interdisciplinary treatment of the patient who underwent the massive chest injury caused by an agricultural machine. The therapy involved the latest treatment methods, such as VAC® therapy, hydro surgery system – VersaJET and the specialist dressings. The patient was transported by the Air Rescue to the Military Institute of Medicine where he initially underwent immediate clamshell thoracotomy which allowed provisional control of the injury. Then, due to the symptoms of the septic shock and massive infection of the chest front wall soft tissues, the VAC® therapy and VersaJet system were introduced. The latter was used to remove necrosis and cleanse the infected tissues. Simultaneously, an intensive multidirectional treatment was performed in the Intensive Care Unit. This included broad‑spectrum targeted antibiotic therapy and nutritional therapy. After the patient’s condition was stabilized and the injured tissues condition improved, it was decided to perform the reconstruction of the front wall of the chest with the musculocutaneous flap from the musculus lattissimus dorsi which was used to close the large loss of the tissues in the front wall of the chest.
