Aortic dissection, also known as aortic coarctation, is often caused by high blood pressure or atherosclerosis, and can be treated with medications such as metoprolol to lower blood pressure, or with surgery. 1. Antihypertensive medication: Controlling blood pressure can reduce the risk of aortic dissection, and drugs such as metoprolol can lower blood pressure very well, but it should be noted that this kind of drug may cause dizziness and headache and other adverse reactions, and patients with atrioventricular block are prohibited from taking this drug. 2. Surgery: In the case of Stanford type A aortic coarctation, this type of aortic coarctation is more dangerous, and once detected, it should be aggressively treated with surgery, which mainly involves reconstruction of the arch and root of the aorta. The most common surgical procedures used are ascending aortic repair or replacement and endoluminal isolation. Since aortic coarctation is a serious cardiovascular emergency and can be life-threatening in the event of rupture, it is important to cooperate with your doctor for appropriate treatment once it is detected.
