Interventional thoracic aortic aneurysm repair is a minimally invasive treatment option for thoracic aortic aneurysms (TAA). Depending on your individual needs, your doctor may recommend either:
St. Joseph's Heart & Vascular Institute is a leader in interventional care. Our cardiologists use the latest digital technology and minimally invasive tools.
An endovascular stent graft is composed of fabric supported by a metal mesh called a stent. It can be used for a variety of conditions involving the blood vessels, but most commonly is used to reinforce an aneurysm. The stent graft is designed to seal tightly with your artery above and below the aneurysm. The graft is stronger than the weakened artery and it allows your blood to pass through it without pushing on the bulge.
Before endovascular stent graft repair:
For both open surgical and endovascular thoracic aortic aneurysm repair, you will undergo follow-up imaging tests within the first few months after the procedure to ensure that the stent is still functioning without significant problems and in the proper location.
After the first year, you will probably undergo yearly imaging tests if your aneurysm is shrinking and no problems are found. You may require more frequent imaging tests if potential problems require closer monitoring.
If your thoracic aortic aneurysm is large or causing symptoms, you need active and prompt treatment. Your doctor may recommend actively treating through open surgical aneurysm repair or endovascular stent-graft repair.
If your TAA is small and not causing symptoms, your physician may recommend "watchful waiting," which means that you will be monitored every 6 months for signs of changes in your aneurysm. Your physician may schedule you for CT or MRI scans every 6 months to watch the aneurysm.
Your doctor will advise you regarding the best option for your particular situation.
