Intraoperative Extracorporeal Membrane Oxygenation Rescue of a Polytrauma Patient With a Complete Right Mainstem Bronchus Avulsion: A Pediatric Case Report.

In pediatric patients experiencing blunt chest trauma, tracheobronchial avulsion injuries are rare but frequently fatal. We report the case of a 13-year-old boy who presented to our trauma center following a semitruck versus pedestrian collision. During his operative course, he developed refractory hypoxemia requiring emergency venovenous (VV) extracorporeal membrane oxygenation (ECMO) support. After stabilization, a complete right mainstem bronchus avulsion was identified and treated.
