How do you treat a thoracic aneurysm?
Treatment for a thoracic aneurysm may include surgical repair or removal of the aneurysm, or inserting a metal mesh coil (stent) to support the blood vessel and prevent rupture. “Thoracic” refers to the part of the aorta that runs through the chest (thoracic aortic aneurysm).
What size thoracic aortic aneurysm requires surgery?
Surgery is generally recommended for thoracic aortic aneurysms about 1.9 to 2.4 inches (about 5 to 6 centimeters) and larger. Surgery may be recommended for smaller aneurysms if you have a family history of aortic dissection or a condition linked to aortic aneurysm, such as Marfan syndrome.
What should you avoid with a thoracic aortic aneurysm?
- Push, pull, bear down or lift anything heavier than 30 pounds (or 10 pounds for patients recovering from surgery).
- Get a tattoo or body piercing.
- Smoke (or be exposed to secondhand smoke) or use any other tobacco products.
- Shovel snow, chop wood, dig earth or use a sledgehammer or snow blower.
- Take illicit drugs.
How do you manage an aortic aneurysm?
For asymptomatic patients, elective repair of the aneurysm is the most effective management to prevent rupture. However, elective aortic surgery is also associated with risks, and thus, elective AAA repair is not recommended until the risk of rupture exceeds the risks associated with repair.
What size aneurysm needs surgery?
If the aneurysm is more than 5.5 centimeters in size, or if it’s rapidly getting larger, your doctor may recommend surgery to repair the aneurysm.
When is a thoracic aneurysm repaired?
Your provider uses imaging scans to decide if you need surgery for a thoracic aortic aneurysm. They often use CT scans to monitor the aneurysm size. Your provider may recommend surgery if the aneurysm is larger than 5.5 centimeters or has grown more than 0.5 centimeters in six months.
How serious is a 4 mm aneurysm?
An aneurysm’s size can also give doctors clues to its level of threat. Aneurysms that are: Less than 3 mm in size have a low risk of rupture. Larger than 3 mm have a higher risk of bursting.
How serious is a 5 cm aneurysm?
Aortic aneurysms less than 4 centimeters in size have a low chance of bursting, but an aneurysm more than 5.5 centimeters in diameter has an increasing chance of rupturing in the next year. One of the things that makes aortic aneurysms so dangerous is that many times, they go undetected until they burst.
Is walking good for aortic aneurysm?
If you have a larger aneurysm and are getting closer to repair, it’s still ok to stay active. These activities are usually safe to do, he says, even with a growing aneurysm: Moderate exercise, like walking, cycling or swimming.
How do you monitor thoracic aortic aneurysm?
If a thoracic aortic aneurysm is suspected, your physician may order the following tests:
- Chest x-ray.
- Computed tomography (CT) scan.
- Magnetic resonance imaging (MRI)
- Echocardiography (an ultrasound of the heart)
- Abdominal ultrasound (to look for associated abdominal aneurysms)
- Angiography (an x-ray of the blood vessels)
Is a 4 cm aorta normal?
A normal aorta is about 3 centimeters—or a little over 1 inch across. An aneurysm occurs when a portion of the aorta has enlarged to at least 1.5 times its normal size.
How big is a 4 cm aneurysm?
An aneurysm occurs when a portion of the aorta has enlarged to at least 1.5 times its normal size. Aortic aneurysms less than 4 centimeters in size have a low chance of bursting, but an aneurysm more than 5.5 centimeters in diameter has an increasing chance of rupturing in the next year.
How serious is thoracic aneurysm?
Complications of a thoracic aortic aneurysm include rupture of the aorta or a life-threatening tear between the layers of the aorta’s wall (aortic dissection). Rupture or dissection can lead to sudden death.
How serious is a 5 mm aneurysm?
Objective. Small unruptured aneurysms (<5 mm) are known for their very low risk of rupture, and are recommended to be treated conservatively. However, we encounter many patients with small ruptured aneurysms in the clinical practice.
At what size do aneurysms burst?
Less than 3 mm in size have a low risk of rupture. Larger than 3 mm have a higher risk of bursting.
Is a 4 cm aortic aneurysm big?
How long can you live with a thoracic aortic aneurysm?
Median survival was 6.6 years. The leading cause of death in this cohort was rupture of the thoracic aortic aneurysm, which accounted for 30% of the deaths. Cardiac events accounted for another 25%, along with pulmonary causes in 15%, cancer in 10%, stroke in 4%, and various other causes of death in 16%.
What should you avoid if you have an aneurysm?

What size aorta require surgery?
What size is considered a thoracic aneurysm?
Aneurysm is defined as dilatation of the aorta of greater than 150% of its normal diameter for a given segment. For the thoracic aorta, a diameter greater than 3.5 cm is generally considered dilated, whereas greater than 4.5 cm would be considered aneurysmal.
How long can a person live with a thoracic aneurysm?
What size does an aneurysm requires surgery?
If the aneurysm is more than 5.5 centimeters in size, or if it’s rapidly getting larger, your doctor may recommend surgery to repair the aneurysm. In many cases, doctors will run a catheter through the patient’s femoral artery in the groin to the site of the aneurysm in the aorta, then implant a stent graft.
At what size do aortic aneurysms burst?
AAA rupture risk is typically determined by size, and it has been shown that in the 5 years following AAA diagnosis, rupture occurs in approximately 2% of AAAs less than 4 cm in diameter and in more than 25% of AAAs larger than 5 cm.
