Hi; re: your post and the tube.The intubation tube for anesthesia is placed either via the nose or frequently, the mouth, pass the throat and then into the TRACHEA, to aerate the lungs not the esophagus.The tube can irritate the throat. Whether or not there is any "irritation" to the aorta/esophagus is best answered by an anesthesia doc or nurse.I do follow what you're asking. Good luck. Joan.
