Aneurysm of the inner border of the aortic arch is usually a more dangerous disease, which may rupture. Once the aortic arch aneurysm ruptures and leads to hemorrhage, it is easy to induce death, aortic valve closure insufficiency, obstruction of the blood supply to the tissues and organs, and other serious consequences, and it should be treated by surgery as early as possible, and medication-assisted treatment and so on. Aortic arch aneurysms are generally caused by atherosclerosis, infection, trauma and other factors that lead to localized weakness and hypotonia of the aortic arch wall, which produces aneurysmal dilatation under the pressure of blood flow, including aneurysms of the proximal part of the aortic arch, aneurysms of the distal part of the aortic arch, and aneurysms across the aortic arch. When aortic arch aneurysms are detected by CT, MRI, etc., surgical treatment is usually preferred, with the aim of stopping the progression of aortic coarctation and avoiding the occurrence of organ blood supply obstruction and aortic aneurysm rupture. Medication-assisted treatment, such as irbesartan, nifedipine, propranolol hydrochloride, etc., is also prescribed to control blood pressure and minimize the chance of aortic aneurysm rupture. If an aneurysm of the inner edge of the aortic arch is detected, it should be promptly consulted and treated in accordance with medical advice to avoid delays.
