What is TEVAR in vascular surgery?

Thoracic endovascular aortic repair (TEVAR) is a procedure to treat an aneurysm in the upper part of your aorta. The aorta is your body’s largest artery. An aneurysm is a weak, bulging area in the aorta wall. If it bursts (ruptures), it can be deadly.

Is TEVAR heart surgery?

Thoracic Endovascular Aortic Repair (TEVAR) is a minimally invasive procedure to repair the major blood vessel in the body, called the aorta. The aorta exits the heart and carries blood to all the organs and the rest of the body.

How do you do TEVAR?

During TEVAR, our doctors fit a stent (fabric-covered, metal mesh tube) inside the damaged part of the aorta to provide reinforcement. They place the stent using a thin tube (catheter) inserted through an artery in the groin. Initially, the stent is collapsed. Once the stent is in place, the doctor expands it.

How long do aortic stents last?

What is the typical lifespan of a stent? Stents are small tubes inserted into your body to reopen a narrowed artery. They are made to be permanent — once a stent is placed, it’s there to stay. In cases when a stented coronary artery does re-narrow, it usually happens within 1 to 6 months after placement.

Who performs a TEVAR?

Background: Endovascular aneurysm repair (EVAR) and Thoracic endovascular aortic repair (TEVAR) are commonly performed by interventional radiologists, cardiologists, general surgeons, cardiothoracic surgeons, and vascular surgeons, with each specialty having differences in residency structure, operative experience, and …

How is a TAVI procedure done?

Transcatheter aortic valve implantation (TAVI) involves inserting a catheter into a blood vessel in your upper leg or chest and passing it towards your aortic valve. The catheter is then used to guide and fix a replacement valve over the top of the old one.

How long does an aortic stent last?

Current generation stent grafts correlated with significantly improved outcomes. Cumulative freedom from conversion to open repair was 93.3% at 5 through 9 years, with the need for prior reintervention (OR, 16.7; P = 0.001) its most important predictor. Cumulative survival was 52% at 5 years.
