Level 3 tracheal injury in acute coronary syndrome treated conservatively with extracorporeal membrane oxygenation.

Level 3 tracheal injury, characterised by complete laceration with oesophageal or mediastinal soft-tissue herniation, is conventionally indicated for surgical repair. We present the case of a woman in her 60s with level 3 tracheal injury in acute coronary syndrome who was treated successfully without surgery. Venoarterial extracorporeal membrane oxygenation (ECMO) was introduced during lung-rest management to avoid positive pressure ventilation, and percutaneous coronary angioplasty was performed. Venoarterial ECMO was switched to venovenous ECMO when the haemodynamics improved. The tracheal injury healed spontaneously in 10 days, and ECMO was withdrawn on day 15. The patient made full recovery and was discharged on day 51.
