Innominate artery injury: a catastrophic complication of tracheostomy, operative procedure revisited.

A patient presented with profuse bleeding from the oronasal cavity following orofaciomaxillary trauma associated with tracheolaryngeal injury and suspected cervical-spine injury due to collapse of a wall on the face, neck and upper chest. The patient was gasping, coughing blood and was unable to speak. Threatened airway was diagnosed. Inability to maintain oxygenation on cricothyroidotomy, forced emergency department surgeons to shift the patient to the operating room for definitive airway. During tracheostomy a major vessel was injured. Application of vascular clamp in the event of achieving haemostasis resulted in disappearance of saturation and pulse in the right upper limb, thus we suspected innominate artery (IA) injury. High tracheostomy performed and endotracheal tube passed into the trachea after removing clot and overcoming compromised narrow tracheal lumen. The injured IA was repaired and the patient survived for 14 days. On postoperative day 14 he died following profound bleeding into the tracheobronchial tree and asphyxia/apnoea. Tracheoinnominate artery fistula was detected at autopsy.
