Penetrating ulcers of the aortic arch require surgical treatment. If a penetrating ulcer of the aortic arch does exist, the exact location of the ulcer will determine the type of surgery. If the ulcer is distal to the left subclavian artery and more than 1 cm from the opening of the left subclavian artery, a thoracic aortic stent may be placed. If the ulcer opens in the middle of several branches of the aorta, surgical treatment is somewhat more complicated and requires grafting of the cephalic trunk, the left common carotid artery, and the left subclavian aorta, followed by stenting. Covering the ulcer opening and the aortic bifurcation. If the ulcer is small and away from the aortic branches in front of and behind the ulcer, it can be sealed with a blocker. Patients need to pay attention to more rest in their normal life, preventing labor and staying up late, avoiding spicy and stimulating food, and also conducting regular review.
