Aortic herniation requires treatment. Asymptomatic patients need to control the causative factors, such as controlling blood pressure levels and lipids, and surgery if necessary. All aortic arch herniations have a clear cause, and patients may have hypertension or atherosclerosis. For asymptomatic patients who do not have severe dilatation of the aortic arch, it is important to control underlying conditions such as blood pressure and lipids to avoid further progression of the condition. Patients with aortic arch herniation are advised to undergo CTA of the aortic arch to clarify the extent of the aortic arch lesion. If the patient develops an aneurysmal dilatation of the aortic arch, the severity of the condition should be assessed, and patients with severe dilatation may require surgery, such as implantation of a stent or aortic arch replacement. Patients with a herniated aortic arch should have regular reviews and visit the cardiac surgery department regularly and be given treatment under the supervision of the doctor. If there is any discomfort, seek medical attention promptly.
