A herniated aortic arch means that an aneurysm has developed in the aortic arch. Due to the local protrusion, it can cause further damage to the intima of the artery, and there is a possibility of arterial rupture or arterial entrapment at the protruding site, which requires medication to control blood pressure after this problem is detected to prevent the protrusion of the aortic arch from increasing further. If the patient has a high suspicion of rupture of the protruding part of the aortic arch, surgical treatment is required to remove the lesion in order to prevent rupture and bleeding of the aortic arch. This is because a rupture in this area can easily cause acute hemorrhagic shock and endanger the patient’s life.
