“…TIF often occurred within the first 3 weeks of tracheostomy creation, 4,5) but has been reported to occur long after the procedure, especially in patients with neuromuscular disorders. [6][7][8] Identified risk factors included tracheostomy below the fourth tracheal ring, 9) high located innominate artery, pressure necrosis of tracheal wall related to overinflated tracheostomy tube cuff, local infections, prolonged positive pressure ventilation, and spinal deformity. 10,11) Our patient developed TIF more than 12 years after tracheostomy; the slide tracheoplasty performed 2 years ago might have changed the anatomy of innominate artery relative to trachea and the chronic mycobacterial tracheobronchitis might have contributed to the gradual necrosis and structural change of trachea, eventually led to this episode of near fatal event.…”
