Abstract
Background Traumatic injury of the trachea is rare, especially complete transection. Its operative revision requires an interdisciplinary approach.
Case Description We hereby present a rare case of complete transection of the trachea by accident. To stabilize the patient and to allow for safe surgery, veno-venous extracorporeal support was initiated via the subclavian artery and the femoral vein. The patient was subsequently operated, and the trachea re-anastomosed with favorable outcome.
Conclusion This rare case of an accidental transection of the trachea shows the importance of a good emergency rescue chain and the ability to facilitate interdisciplinary approaches in tertiary hospitals.

Case Presentation
A 42-year-old youth worker suffered from traumatic tracheal injury during a night-time boat trip caused by a fishing line stretched across the river. He was found conscious and referred by paramedics to the nearest, primary emergency department (emergency room [ER]). After rapid hemodynamic deterioration at the primary ER, he was intubated directly through the cricotracheal wound and referred to our tertiary hospital for further treatment. At administration, the patient was sedated and cardiopulmonary impairment was regulated with moderate doses of norepinephrine and oxygen. A subsequent trauma scan using computed tomography was initiated ( Fig. 1 ).

Due to the possibility of further hemodynamic instability and especially difficult airway management during the emergent operation for trachea reconstruction, we decided to partially support the patient using extracorporeal life support (ECLS). He was placed in the operating room, where under radiographic guidance a 15-Fr (French) cannula was inserted into the left subclavian vein. An additional 23-Fr cannula was inserted into the left femoral vein and ECLS support was initiated after the application of 5,000 IE heparin at the rate of 4 L/min, SpO 2 100%. The initial borderline blood gases improved, and we were subsequently able to fully inspect the traumatic damage after the removal of wound drapings and the cervical collar used for fixation during interhospital transfer. Close inspection of the wound showed a 15-cm long, gaping wound down to the intact esophagus and with the larynx detached from the trachea ( Figs. 2 and 3 ). Despite the trauma, no vessels were injured, and bleeding was surprisingly minor. After wound debridement a surgical tracheostoma was formed followed by trachea reconstruction, which was achieved using direct, single stitched sutures. After successful reconstruction, the patient was weaned off the veno-venous-ECLS support and the cannulas were removed without complications. The patient was administered to the intensive care unit. He recovered from the trauma and was administered to the outpatient clinic, but still bearing up with tracheostoma due to paralysis of both vocal cords which is the most commonly associated injury in approximately 50% of all patients with blunt trauma. 1

Conclusion
Blunt trauma to the trachea (“clothesline injury”) is uncommon; however, several case reports have been published. 2 Sharp trauma, causing an open transection of the trachea is even rarer and requires distinct differences in patient management, especially airway management. 3 Airway management remains vital in such a case. Facilitating the 24 × 7 ECLS standby can be of utmost importance in such or a similar case. By using ECLS support, we were able to partially replace the lung function and thus we safely accessed and operated the patient without the need for rapid and possible insecure re-intubation.
