Ascending Thoracic Aortic Aneurysm
Medically reviewed by Drugs.com. Last updated on Jul 7, 2024.
AMBULATORY CARE:
An ascending thoracic aortic aneurysm (ATAA)
is a bulge in the part of the aorta closest to your heart. The aorta is a large blood vessel that goes from your heart down into your abdomen. ATAA can occur if the aorta or its valve is damaged, inflamed, or not formed correctly. An ATAA may continue to grow and rupture (burst), or it may dissect (tear) suddenly. An ATAA that bursts or tears is a life-threatening emergency.

- Coughing or vomiting blood
- Being able to see your neck veins move or pulse
- A heart murmur (whooshing sound)
- Weak pulses in your arms
Call your local emergency number (911 in the US) or have someone call if:

Treatment
may include any of the following:
- Heart medicines may be given to lower your blood pressure (BP) or control how fast your heart beats. This helps prevent your ATAA from growing, tearing, or bursting.
- Cholesterol medicine lowers your cholesterol level to help prevent atherosclerosis (hard or stiff arteries).
- Surgery may be needed to repair your aorta or remove an aneurysm. You may instead need surgery to replace part of your aorta. Your aortic valve may also be replaced if it is not working properly.
Manage an ATAA:
- Manage other health conditions to help prevent your ATAA from growing or bursting. Examples are high cholesterol, high BP, and diabetes. Take medicine as directed and follow your treatment plan. Check your BP as directed if you have high BP. Your provider will show you how to do this. Check your BP 2 times, 1 minute apart. Check as often as directed each day. Keep a record of your readings and bring it to your follow-up visits.
- Follow the meal plan set by your provider. Talk to your provider or dietitian about a heart-healthy or low-sodium meal plan. Heart-healthy meal plans are low in sodium, processed sugar, and some fats. They are high in potassium, calcium, heart-healthy fats, and fiber. These can be found in vegetables, fruit, and whole-grain foods. A meal plan can help you lower your cholesterol and BP levels.
- Follow physical activity instructions. Your physical activity plan may include low-intensity activity, such as walking, yoga, or swimming. Regular physical activity can help decrease your BP and cholesterol levels. You may need to avoid intense physical activity, such as weightlifting or running. Intense activity may raise your BP or put pressure on your aorta. These increase your risk for a tear or rupture. You may also need to avoid contact sports such as football to decrease your risk for a chest injury.
- Limit or do not drink alcohol. Alcohol can increase your BP. Ask your provider if it is okay for you to drink any alcohol. Your provider can help you set limits for the number of drinks you have in 24 hours and within 1 week. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can increase the risk for your ATAA to tear or burst. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products. Avoid secondhand smoke when possible.
- Get vaccines as directed. Some viruses can worsen an ATAA. Get a flu vaccine as soon as recommended each year, usually in September or October. Get all recommended COVID-19 vaccine doses and boosters. A pneumonia vaccine may also be recommended. Your provider will tell you if you need other vaccines, and when to get them.
Follow up with your doctor or specialist as directed:
You may need to return for regular scans to check your aorta for changes. Your doctor or specialist will tell you how often to have the scans. Write down your questions so you remember to ask them during your visits.
