Thoracic Aortic Aneurysm

Thoracic Aortic Aneurysm Treatment Program

Thoracic Aortic Aneursyms have a modern approach to their management with endovascular stent grafting. Intervention through bilateral groin regions allows for deployment of stent grafts with minimal recovery time.

The aorta is a large artery that carries blood from the heart through the abdomen to the legs. The thoracic aorta is located in the chest and is made up of three segments:  the ascending aorta, aortic arch, and descending aorta. A thoracic aortic aneurysm is a bulging or ballooning of any of these segments of the aorta. Similar to a balloon, as an aneurysm continues to enlarge, the walls of the aorta stretch making them much thinner. The aortic aneurysm eventually reaches a point where it loses its ability to stretch any further.  At this point, without any treatment it may rupture, causing potentially fatal bleeding.

There are many factors that can put you at risk of developing a thoracic aortic aneurysm. They may vary significantly depending on the location of the aneurysm itself:

  • Cystic medial degeneration
  • Inherited connective tissue disorders: Marfan syndrome or Ehler-Danlos syndrome
  • Family history of thoracic aortic aneurysm
  • Coronary artery or heart disease; including associated risk factors such as high blood pressure, high cholesterol, diabetes, smoking, age greater than 55, and male gender
  • Infection or syphilis
  • Takayasu’s arteritis
  • Trauma

How is it diagnosed?

There may be no symptoms until the aneurysm has enlarged significantly, is leaking, or has ruptured. In this instance, symptoms that may be reported include neck, chest, or back pain; swelling of the head, neck, or arms; and wheezing, coughing, or shortness of breath.

Tests that may confirm diagnosis:

  • Computed tomography scan (CT)
  • Magnetic resonance imaging (MRI)
  • Echocardiogram
  • Transesophageal echocardiogram (TEE)
  • Chest x-ray

What are my treatment options for a Thoracic Aortic Aneurysm?

If your aneurysm has been discovered early, is still small (less than 5.5 centimeters), and you have no symptoms, surgery may not yet be necessary. In this case, your vascular surgeon will closely monitor the growth of your aneurysm every 6-12 months by obtaining CT scans. Additionally, it is important to quit smoking and control your risk factors, such as keeping your blood pressure or high cholesterol under control with medication.

Once your aneurysm has reached 5.5-6 centimeters, the risk of rupture is much higher and surgery is recommended. Your vascular surgeon will decide what the best options are for you at that time and discuss complications and risks. There are two choices for treatment:

  • Traditional Open Repair of TAA:  An incision is made into your chest or just under the breastbone to visualize the area of the aneurysm. The aneurysm is opened and a cylinder-like tube called a graft is placed within the aorta to repair it.  Ultimately, the weakened area of the artery is relined with a sleeve of material to strengthen it and prevent rupture of the aneurysm. At times, there is also involvement of the aorta adjacent to the heart. If this is the case, sometimes heart surgery may be required at the same time. Hospital stay with this procedure is about 7-10 days, with full recovery depending on other conditions present.
  • Endovascular Repair of TAA: This repair may only be used if the location and shape of the aneurysm is suitable to allow for correct deployment of the graft. It is a less invasive approach than traditional surgery, with this repair involving only a small incision in the groin. Endovascular means that the procedure uses long thin tubes inside your body called catheters. Under guidance of an x-ray, a small catheter is placed through the groin incision and used to pass a cylinder-like tube called a graft up into the aneurysm. This graft is placed so that the ends fit neatly into the non-diseased portion of the artery at the opposite ends of the aneurysm. This is relining the weakened area of the aorta with a strong sleeve of material, thus preventing rupture of the aneurysm. Hospital stay for this procedure is 2-3 days, with full recovery about 1 week.
