Two main types are described: Type A starts near the heart and Type B starts farther down the aorta. People typically have sudden severe chest or back pain that may be described as tearing or stabbing, and weakness or shortness of breath can occur while blood flow to organs is reduced. High blood pressure is the most common risk factor, and some connective tissue disorders or stimulant use can increase danger.","Diagnosis is usually made with imaging such as CT, MRI or echocardiography, and rapid care is essential because mortality rises quickly. Type A dissections are treated with emergency open surgery, while Type B may be managed with strong blood pressure medicines or endovascular stent grafts when needed. Initial treatment often includes fast lowering of blood pressure, usually with intravenous medications. Care in an intensive care unit is required for many patients during recovery. Early transfer to a specialized aortic center improves chances."],"wordCount":178,"readTime":2},"vocabulary":[{"word":"dissection","example":"The dissection caused severe pain.","phonetic":"/dɪˈsɛk.ʃən/","definition":"a medical split or separation in a blood vessel wall"},{"word":"echocardiography","example":"Doctors used echocardiography to check the aorta.","phonetic":"/ˌɛk.oʊ.kɑːr.diˈɒɡ.rə.fi/","definition":"a scan that uses sound waves to make images of the heart and aorta"},{"word":"endovascular","example":"An endovascular stent can repair the aorta from inside.","phonetic":"/ˌɛn.doʊˈvæs.kjʊ.lər/","definition":"a procedure done inside blood vessels using catheters or stents"},{"word":"stent graft","example":"A stent graft was placed to reinforce the weak area.","phonetic":"/stɛnt ɡræft/","definition":"a tube made of fabric and metal that supports a blood vessel"}],"quiz":[{"answer":"Type A and Type B","question":"What two types are described?"},{"answer":"with imaging such as CT, MRI or echocardiography","question":"How is diagnosis usually made?"},{"answer":"emergency open surgery","question":"What treatment is used for Type A dissections?"}],"discussion":[{"question":"Do you worry about high blood pressure in your daily life?
