Abstract:
Traumatic rupture of the right main bronchus with pulmonary artery injury is exceptionally rare and often fatal when pneumonectomy is required. An 18-year-old man presented with bronchial transection and pulmonary artery rupture after chest trauma. Venovenous extracorporeal membrane oxygenation enabled oxygenation during controlled thoracotomy. A parenchyma-sparing strategy was adopted: right upper lobectomy, pulmonary artery repair, and end-to-end bronchial anastomosis, avoiding pneumonectomy. Secondary bronchial dehiscence with bronchovascular fistula was successfully managed by omental flap repair. This case demonstrates that early recognition, extracorporeal membrane oxygenation support, and lung-preserving reconstruction are key to survival in catastrophic bronchovascular trauma.
