Fortunately, tracheo-arterial fistula after trach is a rare complication but can occur from erosion into the brachiocephalic trunk, especially with placement of a low lying trach below the third tracheal ring.
|Pressure necrosis from a trach tube can erode into the brachiocephalic artery which runs anterior to the trachea.|
